When and how to do a dormant seeding is a question that is often asked when sowing native seeds. By following these simple guidelines, you can be successful using a dormant seeding.
Make sure your site is prepared and there is no sign of any growing live vegetation present. An exception would be if you were planning on supplementing an existing planting to add more diversity. After the ground temperature drops below 50 degrees, you can start sowing your seed usually in the Midwest this occurs at the end of October or the first of November. Even if you have 2 inches of snowfall, the seed can be broadcast over the snow. Any time in late fall or even winter, seeds can be broadcast.
You can check your soil temperature in your state by googling for soil temperatures for instance in Iowa, you may go to: http://extension.agron.iastate.edu/NPKnowledge/soiltemphistory.html
If you have a small area, one to two acres or less, broadcast your seed by hand. In this instance the seed can be mixed with 10 to 20 parts of wet sand to 1 part seed by volume. After you have thoroughly mixed your seed with the wet sand, divide it into 2 to 4 lots and go over the entire area with each lot. The seed can then be broadcast by hand using an ice cream container under one arm and reaching in with the other hand to grab a handful of this seed matrix. Cast it in a swinging motion just as you would feed chickens. With the next lot of seed, walk in a different direction so as to get a more even distribution of the seed. This is repeated with each lot and going a different direction each time.
Since this is a dormant seeding, we are depending upon Mother Nature to achieve good seed to soil contact which is the most important element in any kind of seeding. Mother Nature will then rain, snow, freeze and thaw. This is just what we want as it will ensure the proper stratification of the seed to break the dormancy code and allow better germination in the spring. Stratification is a process whereby we can either by Mother Nature or human treatment break the dormancy of seeds to enable germination.

Two horticultural professionals took some of the most popular garden myths into the university laboratory to prove or disprove the accuracy of these myths. Dr. Linda Chalked-Scott from Washington State University and Dr. Jeff Gilliam from the University of Minnesota tested these myths under controlled conditions to determine if they really work.
For years we’ve been told that if we water plants on a hot sunny day the sun reflecting through the water droplets will burn the foliage.
We are constantly being warned in books, magazines, and various websites that if we water on a sunny day we will burn the leaves. The premise behind this is the water drops that accumulate on the leaf surfaces act as tiny magnifying glasses, focusing the sun’s energy into intense beams that burn leaves. We’re told that since water conducts heat, wet leaf surfaces are more likely to burn than dry ones. This is one of those myths that refuse to die. Although most of the university web sites dispel this myth, hundreds of other web sites keep the misinformation alive.
If your plants are showing signs of water stress in the middle of the day, by all means you should water them!
Delaying irrigation until the evening (not a good time to water anyway, as this can encourage fungal diseases or the following morning could damage your plants and open them up to diseases.
There are many causes of leaf scorch, but irrigation with fresh water is certainly not one of them.
Wet foliage is not susceptible to sunburn
Analyze site conditions to ensure optimal root and shoot health and prevent drought problems
Any time plants exhibit drought stress symptoms is the time to water them
Ideal watering time is in the early morning; watering during the day increases evaporative losses, and evening watering regimes can encourage establishment of some fungal diseases
Do not overuse fertilizers and pesticides, especially those containing sodium or other salts
If using recycled or gray water, consider running the water through a filtering system before applying it to plants.
Using nursery tags is an accurate method to determine a plant’s final size.
Fall is the ideal time to plant trees and shrubs. Selection can be a tricky practice, especially when site conditions limit size of plantings. Small landscapes require small-scale plantings.
At the nursery, one can be overwhelmed by the variety of deciduous trees and conifers, and even within a species there may be several cultivars from which to choose.
Without any prior knowledge of these plants, gardeners resort to nursery tags to determine mature heights and widths. Armed with this information, one can select those trees and shrubs whose size is appropriate to the site. But does this approach really work?
Many factors determine the mature size of any tree or shrub. The most obvious on plant size is genetic makeup – you only have to look at cultivar names like ‘Midget’ or ‘Giant Candles’ to understand this component.
Geographic location also plays a role in determining height. For instance, trees tend to grow taller in areas where temperatures are more moderate; trees in coastal areas are generally larger than these same species in more interior regions. Within a geographic area, local climate will further influence final size: rainfall and temperature can vary widely within a region. The microclimate of a site will influence tree size due to differences in environmental factors such as drainage, and soil type.
Competition for water, light, and nutrients, will affect not only growth rate but final height as well.
1. Nursery tags most likely contain species information relevant to that nursery’s geographic location
2. Genetics, geography, climate, and plant competition will all influence the maximum height any specimen will obtain
3. To determine the most likely height range for a tree in your landscape, observe how that species performs elsewhere in your area
4. If no local landscape specimens exist for a particular plant, look to the internet for plant performance information from similar climates elsewhere in the world.
Landscape fabric provides permanent weed control for landscapes
Concern over the use of herbicides has caused landscape professionals and gardeners to look closely at non-chemical methods of weed control. Mulches are increasing in popularity as weed control measures and have a number of additional benefits, including water retention and soil protection. Mulches may be organic, inorganic, or synthetic. Synthetic mulches, including geotextiles, are of interest to many consumers and professionals because they are perceived as nonbiodegradable, permanent solutions to weed control.
Developed for agricultural use, geotextiles have found their way into ornamental gardens as landscape fabrics. These fabrics, a vast improvement over the impermeable black plastics still (unfortunately) used for weed control, are woven in such a way that water and gas exchange can occur but light penetration is significantly reduced. Hence, they are effective in reducing weed seed germination in areas where soil disturbance would otherwise induce germination of weeds. Such fabrics have been so effective in reducing weeds in vegetable and ornamental crop production that they have been applied to more permanent landscape installations.
Like the dieter searching for a permanent weight loss pill, so we as gardeners continue to seek permanent weed control solutions. Unfortunately, there is no such permanent fix.
We must remain ever vigilant in our battle with weeds and cannot rely on a product to do this. The fact is that weed control fabrics are not permanent and will decompose, especially when exposed to sunlight.
For permanent landscapes, they are not a long term solution and in fact can hinder landscape plant health.
Some of these facts are listed below.
Any organic matter or soil on top of the fabrics will hasten their colonization by weeds; this precludes covering the fabric with anything but inoert mulch like pebbles. It also requires continual maintenance to keep the fabric free of debris. Weeds will eventually grow on top of and through these fabrics, making their removal difficult.
Geotextiles degrade in the landscape in as little as one year if unprotected from sunlight.
The aesthetic quality of landscape fabrics is minimal; it becomes worse as the materials begin to degrade.
Personally I had a situation where field bindweed grew some 25 feet under landscape fabric before emerging at the edge of the bed, seeking sunlight.
In closing, I expect some of you might disagree with some of these findings. However remember that this research was done in reputable university labs under controlled conditions. Each of us will draw our own conclusions.

Wildflowers are one of Mother Nature’s loveliest gifts. Their changing panorama of colors, shapes, sizes and heights provides delight throughout the seasons. Wildflowers can be used anywhere. In the home landscape they are ideal for creating colorful beds and borders, as well as offering a lower-maintenance alternative for large areas or replacing turf grass. Wildflowers can be planted to cover large, open areas or assist in the recovery of a landscape that has been damaged or destroyed by the actions of people, a natural disaster, or the spread of invasive plants.
WHAT IS A WILDFLOWER?
Wildflower is not an exact term that is well defined. Some people say a wildflower is a plant that was not intentionally seeded or planted and grows without cultivation. Others classify a wildflower as any plant growing without the help of man regardless of the plant’s country of origin. Still others define a wildflower as a plant found in a specific geographic area that was grown from seed or plants also from that area.
Wildflowers and other plants that were growing before European settlement in what we now call the United States, Canada and Mexico are called native plants or indigenous species. Other plants, often referred to as exotics or aliens, were originally brought here from another part of the world. Many exotic species including flowers, grasses, trees and shrubs are among our favorite garden plants. A few, including some wildflowers, have escaped and become established as part of a local environment or naturalized. Some exotic species have even become invasive and are considered noxious weeds that need to be eradicated.
HISTORY OF WILDFLOWERS
Many of our favorite wildflowers have been growing in European gardens for centuries. Even some of our native wildflowers enjoyed more popularity in Europe than in the U.S. where they went unnoticed by gardeners. When early explorers came to North America, they discovered the bounty of plants growing in the New World. They eagerly brought many of these plants back to Europe where they were sought after by gardeners wanting something new and different for their gardens.
During colonial times, ornamental flowers were often grown in the Pleasure Garden or Pleasure-Ground, the designation for the flower garden. President George Washington had flower gardens at his home but most of his written notes were about the trees and shrubs he planted at Mt. Vernon, One native wildflower that Washington did plant and record was Cardinal Flower (Lobelia cardinalis). He probably grew many foreign or exotic flowers since Washington avidly collected and traded plants with correspondents in Europe.

President Thomas Jefferson, an avid horticulturist, plant collector and seed saver, grew wildflowers in his garden. He also noted planting Cardinal Flower after it was recommended by his nurseryman friend, Bernard McMahon, who included it in his 1806 book “The American Gardener’s Calendar”, the first horticultural reference for American gardeners. While Cardinal Flower may have been one of the first trendy plants in the New World, it’s interesting that this North American native wildflower was introduced in Britain in 1626, more than 150 years before being mentioned in American references. McMahon noted “Here we cultivate many foreign trifles and neglect the profusion of beauties so bountifully bestowed upon us by the hand of nature.”
Other plants in Jefferson’s garden may have been from the 290 native plants described and collected by Meriwether Lewis during the Lewis and Clark Voyage of Discovery in the early 1800’s. More than half of the plants were new discoveries to white people including Lewis Flax (Linum lewisii) (one of many plant species named after either Lewis or Clark) and Scarlet Globemallow (Sphaeralcea coccinea). They also described Blanketflower (Gaillardia aristata) and Purple Coneflower (Echinacea purpurea).
Informal and wildflower gardens became fashionable with the publication of The Wild Garden in 1870 by England’s William Robinson who described them as “a delightful feature of a place”. This style of garden contrasted with the highly manicured and formal designs that had been popular in American and Europe. Wild gardens featured hardy, herbaceous plants, including both native and exotic species. They were designed and placed where they would thrive with little additional care.
The cottage and old-fashioned gardens of the 1800’s also included a few native perennial wildflowers but mostly focused on designs that included peonies, hollyhocks, phlox, roses, violets and other European favorites. By the end of the 1800’s many landscape designers began to emphasize hardy herbaceous plants in recognition of their lower maintenance. Noted horticulturist and botanist Liberty Hyde Bailey wrote, “The interest in native plants has never been so great as now.”
Wildflowers and native plants have continued to attract attention throughout U.S. gardening history. They are currently experiencing a resurgence in popularity by both gardeners and public officials for their beauty and their valuable contributions to the environment.
WHY PLANT WILDFLOWERS
A garden of wildflowers offers benefits to both the gardener and the environment. Once established, properly chosen wildflowers require less maintenance than traditional landscape plantings which can mean less watering, fertilizing, pest control and mowing. Some plants have deep root systems that prevent water run off and soil erosion, and enable them to withstand drought. Their growth also brings earthworms and beneficial soil microorganisms to enhance soil health. And colorful blossoms can be arranged into lovely, casual bouquets that brighten the home.
Flowers provide nectar and pollen sources for bees, butterflies and other pollinators, while ripened seeds are a food source for birds and wildlife. Current research suggests that native plants and flowers might be more attractive to native bees than exotic flowers. Even a small area in a garden or landscape planted with wildflowers that bloom at varying times throughout the growing season helps attract and support pollinators.
SOME POPULAR PERENNIAL WILDFLOWERS
Many of these beautiful yet hard-working plants are equally at home in garden beds and borders as they are in larger wildflower plantings and restoration projects. Purple coneflower (Echinacea purpurea), California poppy (Eschscholzia californica), columbine (Aquilegia canadensis), butterfly weed (Asclepias tuberosa), and black-eyed or brown-eyed Susans (Rudbeckia triloba and R. hirta) are among the popular wildflowers planted by American gardeners, all of which happen to be native to the U.S.
One of the most admired wildflowers is Purple Coneflower (Echinacea purpurea). It is native to the Midwestern prairies and dry, open woods of the Southeast but can be found in gardens from Maine to California because it is fairly adaptable to most types of soil and does well even in dry conditions. Plants flower from late spring to early fall attracting butterflies and bees to the large, purple, daisy-like flowers. After the long-lasting blooms drop their petals, the distinctive seed heads develop and provide food for goldfinches and other birds. (Zones 3-8)
Wild Bergamot (Monarda fistulosa) is native to a large part of the country including the Northeast, Midwest and Rocky Mountain region. Also called Beebalm, the whorls of pink to lilac colored flowers open in summer to attract bees, hummingbirds and a variety of other pollinating insects. It gets the name Wild Bergamot from the aromatic leaves that have a scent reminiscent of the bergamot orange tree of Europe. Monarda had many medicinal uses to the Native Americans. Today the leaves are often used to make tea. Plants do best in dry open areas and woodlands but can grow in moist soils as long as they are well drained. (Zones 3-9)
Eastern Columbine (Aquilegia canadensis) despite its species name is native to the East and Midwest U.S. as well as eastern Canada. It is one of about 30 species of Columbine found in North America. Columbine is often found in a shady woodland setting though they have a deep taproot that enables them to grow in dry sites. The colorful red and yellow flowers that open in spring and summer are a favorite of hummingbirds. Blue Columbine or Rocky Mountain Blue Columbine (Aquilegia caerulea) has beautiful blue and white flowers and is one of the many columbines found in the western U.S. It is the state flower of Colorado. (Zones 3-9)
New England Aster (Symphyotricum novae-angliae, previously Aster novae-angliae) is a favorite of many gardeners for the beautiful violet-purple flowers that cover the plant in fall. Its native range is from New England all the way west to the Rocky Mountains and as far south as Tennessee and North Carolina. Plants grow best in areas with full sun and moist but well-drained soils. Valuable in the garden and any wildflower planting for its late season color, New England aster is also a nectar source for Monarch butterflies as well as attracting native bees and pollinators. (Zones 3-7)
California Poppy (Eschscholzia californica) is perennial in its native California but grown as an annual in colder climates. Spanish explorers who saw the California hillsides covered with the golden orange poppies called the area the Land of Fire. It was introduced into European gardens in the 1830’s. California Poppy has golden-orange, silky, saucer-shaped flowers that open during the day and close at night or on cloudy days. Plants bloom best in the cool weather of spring and fall. In mild climates it will bloom several times during the year. In colder climates, it may self-seed in the spring and flower again in the fall. California Poppy is the state flower of California. (Zones 8-10)
While some perennial wildflowers adapt to a range of growing conditions and will grow throughout the U.S., other wildflowers prefer a specific region of the country or very specific environmental conditions. Chocolate Flower (Berlandiera lyrata) is a delightful treasure with cute, yellow, daisy-like flowers that exude the smell of chocolate in the morning. However, it is native to the dry parts of Kansas, Colorado and south to Arizona into Mexico so it loves hot sun and poor dry soils. Grow it in soil that’s even halfway decent and it gets leggy and flops over. (Zones 5-9)
Indian Paintbrush (Castilleja sp.) is another much admired wildflower that seems to grow without care in its native environment that ranges throughout North America depending on the species. It derives its name from the striking orange-crimson spikes that appear in spring and resemble a brush dipped in paint. However, Indian Paintbrush can be difficult to grow from seed and establish in the garden. They are considered hemi-parasitic which means they need to grow in close proximity to other wildflowers and grasses. Indian Paintbrush produces roots that attach themselves to a range of plants that grow nearby to obtain some nourishment. Without these host plants, Indian Paintbrush declines and eventually dies. It is a challenge for even experienced gardeners but could surprise you if planted in the right conditions. (Zones 3-9)
HOW TO GROW WILDFLOWERS
Liberty Hyde Bailey once said “A garden requires patient labor and attention. Plants do not grow merely to satisfy ambitions or to fulfill good intentions. They thrive because someone expended effort on them.”
Growing wildflowers requires the same type of care as traditional ornamental plants. Start with high quality seed and healthy plants. Be sure to select varieties that are suited to your conditions. Wildflowers will grow and bloom best when the environmental conditions meet their requirements. Sun exposure, availability (or lack) of moisture, and soil type all affect plant growth.
HOW TO CHOOSE WILDFLOWERS
Before purchasing seed or plants, think about what you are trying to achieve with your planting. If you want only native wildflowers in your garden find out what is native to your region and what type of growing conditions are needed. Do you want to attract bees and other pollinators or encourage butterflies to visit your garden? Look for plants that produce the type of flowers preferred by these insects. Are you interested in a garden that is filled with color from spring to fall? Choose a mix that has a variety of flowers and bloom times.
Some wildflowers have very specific soil, water, light, temperature and fertility requirements and won’t grow outside of a specific geographic range or set of conditions. Others are easier to grow because they have adapted to a wide range of environments. Does the plant like full sun, partial sun or a shaded location? Does it require constant moisture or will the plant survive periods of drought during the year? Does the plant like rich, fertile soil or does it grow better in a poor soil with lower fertility. Choose plant varieties that are matched to the conditions of your site.
Many types of wildflower mixes are available from seed suppliers. Some mixes contain only native wildflowers and may be formulated to grow in a defined geographic region or climate. Other mixes contain varieties that are both native and exotic. Some mixes have a balance of annual and perennial species to provide fast color and long-term beauty. Other mixes contain mostly annual flowers for a quick-growing wildflower garden. Not all of the wildflowers contained in mixes will grow in every garden but there are usually enough different types in each mix to provide a nice variety. Remember that successful wildflower gardens are created over many years as plants that are best adapted to your garden conditions become established and thrive.
There are many sources available to help you find the best native wildflowers for your garden. The Xerces Society (www.xerces.org) has several fact sheets and publications that suggest good native plants for geographic regions in the U.S. The Lady Bird Johnson Wildflower Center has an extensive database of commercially available native plants that can be searched to provide recommendations by state (www.wildflower.org). Local native plant societies and government organizations are also good sources of regional information.
PREPARING THE SOIL
The next step in creating an eye-catching field of flowers is to prepare the soil by removing weeds and other unwanted vegetation. If the soil is compacted, till lightly so the soil is loose and germinating seeds can put down roots. A bow rake is great for loosening the top layer of soil. Digging or roto-tilling too deep will bring up weed seeds and other plants that will need to be removed later to avoid competing with the wildflower seeds. While it may not be practical or necessary to amend the soil before planting wildflowers, you can add organic matter such as compost or well-rotted manure before planting depending on the site.
PLANTING FROM SEED
Wildflower seed and seed mixes can be planted in either spring or fall. Spring rains help seeds germinate and plants get established before many weeds have a chance to grow. In warm climates, fall is a good time to plant wildflowers when cooler temperatures and winter moisture provide better conditions for seed germination and growth. In cold climates, a dormant seeding of wildflowers can be done in the fall when temperatures are low enough that seed will not germinate until weather warms up the following spring, similar to what happens in nature. Some seeds, especially many of our native perennial wildflower species, need a chilling period to break their dormancy. This is provided naturally by the change in temperatures from winter into spring.
Scatter seeds by hand or with a small spreader. Seeds can be raked into the soil or lightly covered with soil. Water thoroughly right after planting and keep seeds and seedlings moist for about 4-6 weeks. Gradually reduce watering as seedlings develop. Identify and remove weed seedlings as soon as possible since they will compete with wildflowers for water, nutrients and space. For dormant seeding, watering after planting seeds is not necessary.
CARE OF THE WILDFLOWER GARDEN
A wildflower planting just like a colorful meadow created by Mother Nature will look different from month to month and year to year. Annual flowers are more abundant at first because they grow and flower quickly. In following years perennial plants become established and start flowering, in addition to annual flowers that may reseed themselves.
The first year is a time to help wildflowers get established. Not all seeds will germinate right away but may be waiting for the right environmental conditions before they begin to grow. This is especially true with perennial wildflowers so don’t get discouraged or be disappointed if you don’t have that instant flower meadow. For more immediate results you may want to combine seeding wildflowers with planting a few container-grown plants. Plants will quickly get established and compete with weeds that may appear. Be sure to identify and remove weeds when they are small to prevent them from spreading Depending on needs of your wildflowers provide additional water if rainfall is sparse, especially during periods of extended hot temperatures. Avoid cutting flowers after they bloom so they can go to seed. Seed will drop to the ground and spread to fill in your planting.
During the second year, you may see new plants grow from seeds that didn’t germinate the first year. Water if rainfall is not adequate, especially in the spring. Additional water may be needed in the summer during extreme or extended periods of hot weather. Continue to remove weeds as they appear. As wildflowers become established the need to weed should taper off. Fill in bare spots with additional seed or container-grown plants.
After the third year and beyond your wildflower planting should require minimal maintenance. Remove large weeds that may move in. You may want to move plants that have grown too close and are crowding each other. Use them to fill in bare spots or sow additional seed to cover those spots. Additional water may be needed in the summer during extreme or extended periods of hot weather. Fertilizing is generally not required. In a garden setting, you can mulch around established plants with compost or well-rotted manure. Cutting or mowing wildflowers in fall to a height of about 6 inches will keep the planting looking neat and help spread seeds. Periodically disturbing the soil by digging or raking can also help regenerate a wildflower garden by creating good soil contact with seeds that have fallen to the ground.
Some wildflowers, especially prairie plants and grasses, benefit from being burned every few years. Fire occurs in many ecosystems as a way to get rid of woody plant invaders that move into a site as part of natural plant succession. Fire also helps break the dormancy of some seeds and stimulates the growth of other species. However, burning should only be done by someone with the understanding and expertise to do it safely and effectively. In the home landscape mowing, hoeing, digging and other means of soil disturbance can achieve the same goal.
WHERE TO BUY WILDFLOWERS
Gardeners have many choices when creating a wildflower garden. Local nurseries and garden centers sell both seeds and live plants. Retail, Internet, and catalog seed companies sell wildflowers as individual species and mixes. Many seed companies also sell mixes for a variety of special uses—wildflowers for cutting, fragrance, partial shade, attracting butterflies or pollinating insects, and more.
Digging plants from the wild is not recommended and might be illegal. State and federal laws protect some native plant species that are threatened or endangered. Collecting seed must be done carefully. Removing too much seed could reduce or destroy a wild plant population.
The National Garden Bureau has several members that sell wildflowers including many North American native wildflowers. Choosing the right plants for your wildflower garden will create a beautiful landscape to be enjoyed for many years.

Silkweed (Asclepias Syriaca) – Becoming rarer (especially north of Iowa) in moist to wet prairies throughout most of the Tallgrass region, Prairie Milkweed can reach heights up to 3 1/2 feet. Similar to and often confused with the more common “Common Milkweed”, the flowers are a deep reddish-pink and occur in clusters of up to 40 near the top of the plant. Blooms from June through mid-August. Asclepias, from the Greek God of healing and medicine. Syriaca is from the Latin word for “of Syrian origin”.
The Milkweed Family has a long history of medicinal use. Asclepias incarnata was also cultivated for food uses, so it has been a valuable plant of the tallgrass biome for thousands of years. Some tribes added the flowers and bulbs to soups, some used the flowers stewed and served almost like preserves, immature pods were often cooked with buffalo meat and still others used the immature flower clusters and fruits as a cooked vegetable.
There are more than 25 species of milkweed found across the US with a dozen alone in the Tallgrass Biome. It is this species, Silkweed or Common Milkweed that enjoys the most popularity with edible plant enthusiasts.
Medicinally, the ground root of this species was used to induce temporary sterility, tea made from the root was used to “expel internal parasites” and the ground seeds were used in a poultice to draw the poison from a rattlesnake bite.
During WWII, the sap of the milkweed family plants were used experimentally to provide a rubber substitute. The silk produced by the seed pods was also used as a substitute for kapok in flotation devices for many years.
Edible Uses: Unknown
The root is anodyne, diaphoretic, diuretic, emetic, expectorant and purgative. It has been used in the treatment of asthma, kidney stones, venereal disease etc. Caution is advised, see the notes above on toxicity. An infusion of the pounded roots has been used by the women of some native North American Indian tribes to promote temporary sterility. The leaves and/or the latex are used in folk remedies for treating cancer and tumours. The milky latex from the stems and leaves is used in the treatment of warts. The latex needs to be applied at least daily over a period of up to a few weeks to be effective. The stems can be cooked and applied as a poultice on rheumatic joints. One reported Mohawk antifertility concoction contained milkweed and jack-in-the-pulpit, both considered contraceptive. Dried and pulverized, a fistful of milkweed and three Arisaema rhizomes were infused in a pint of water for 20 minutes. The infusion was drunk, a cupful an hour, to induce temporary sterility. The rhizome is used in homeopathy as an antioedemic and emmenagogue in the treatment of dropsy and dysmenorrhoea.
A good quality fibre is obtained from the inner bark of the stems. It is long and quite strong, but brittle. It can be used in making twine, cloth, paper etc. The fibre is of poor quality in wet seasons. It is easily harvested in late autumn after the plant has died down by simply pulling the fibres off the dried stems. It is estimated that yields of 1,356 kilos per hectare could be obtained from wild plants. The seed floss is used to stuff pillows etc or is mixed with other fibres to make cloth. It is a Kapok substitute, used in Life Jackets or as a stuffing material. Very water repellent, it can yield up to 550 kilos per hectare. The floss absorbs oil whilst repelling water and so has also been used to mop up oil spills at sea. Candlewicks can be made from the seed floss. In cultivation, only 1 – 3% of the flowers produce mature pods. It is estimated that yields of 1,368 kilos per hectare could be obtained from wild plants. Rubber can be made from latex contained in the leaves and the stems. It is found mainly in the leaves and is destroyed by frost. Yields of 197 kilos per hectare can be expected from wild plants, it is estimated that by selection these yields could be increased to 897 kilos. Yields are higher on dry soils. The latex can also be used as a glue for fixing precious stones into necklaces, earrings etc. The latex contains 0.1 – 1.5% caoutchouc, 16 – 17% dry matter, and 1.23% ash. It also contains the digitalis-like mixture of a- and b-asclepiadin, the antitumor b-sitosterol, and a- and b-amyrin and its acetate, dextrose and wax. Pods contain an oil and a wax which are of potential importance. The seed contains up to 20% of an edible semi-drying oil. It is also used in making liquid soap.

I recently moved into an older home with a great cobblestone sidewalk in the back garden. However, weeds like to grow between the stones. I hesitate to use an herbicide because I don’t want to damage the nearby flowers, which include everything from tea roses to daisies. Any suggestions on how to rid the sidewalk area of the weeds? I once was told that common table salt could be used between the cracks of the stones. Is this a possibility?
It sounds like you’ve inherited a lovely garden retreat! Salt would probably make the soil inhospitable to plants and soil organisms in your walkway, but there may be danger of the salt leaching into the soil and affecting the plants you want to preserve. How about these alternatives? Some folks like to plant low-growing herbs, such as creeping thyme or dwarf peppermint, between flagstones in a walkway. The herbs grow into a mat, discouraging other plant growth, and as you walk, you’re surrounded by the fragrance of the herbs. You could rent or buy a flame weeder, and burn off the weedy growth. You could also clean out the vegetation that is there by using a low-impact, soap-based contact herbicide. The active ingredients are fatty acid salts which kill plant cells on contact, but which do not persist in the environment. Once you weed the area, you could put down a thick layer of bark mulch, sand or other material between the stones to discourage growth in the long term.
