Interesting Tidbits

Smooth hairless stem. The central cone of the flower turns from light green to yellow which is surrounded by downward pointing petals. May need staking in garden situations but otherwise very hardy. (Ontario Native Plants 2002) This species is native to some parts of Canada and is naturalized in others. A double flowered form is also used as an ornamental in flower beds and is usually called golden glow. Habitat Information: Green headed coneflower is the only coneflower native to the Toronto region. It is the largest coneflower at sometimes well over 12 feet tall if it enjoys where it is, but can morph to 3 feet tall if in dryer and more impoverished soil conditions. It is usually found in wet conditions, sunnier clearings in swamps, forest floodplain clearings, in moist thickets, ditches. Not common among other coneflowers, it does not inhabit dry prairies or meadows. It has a showy yellow flower with a what looks like greenish yellow flower central disc, which may give this plant its name. (Evergreen) It resembles grey headed coneflower, but has leaves that are less cut, a darker green, and is usually a much larger plant. (Evergreen) The common goldfinch occasionally eats seeds. The foliage may be poisonous to some mammals. (Illinois Wildflowers) Garden Uses: This plant can be an aggressive seeder in gardens, and because it is so large, can take over a small area quickly. It is a great plant for naturalization, as it can make a great impact with it's large size in newly restored landscapes, and naturalizes well, competing with weeds. It can tolerate partial, and even full shade, tolerating a wide range of soils. (Evergreen) Traditional Edible, Medicinal Uses: Cure for indigestion. (Densmore, F. (2005). Strength of the Earth, p. 342, as cited in Indiana Native Plant and Wildflower Society) Insect Relationships: Long tongued bees, short tongued bees, predatory wasps, butterflies, skippers, moths, a variety of fly species. This plant is the host for caterpillars of the butterfly Chlosyne nycteis (silvery checkerspot) and some moths (Synchlora aerata, Eupithecia miserulata). (Illinois Wildflowers) Traditional Edible, Medicinal Uses: Poisonous to cattle, pigs, sheep. Consider with caution that young dried leaves, roots and shoots are edible raw or cooked. Some caution is advised when using as this plant, as may be TOXIC in large quantities to humans. Leaves are said to be edible, cooked in spring for 'good health'. The stems can be dried. Tea made from root for indigestion. Poultice from flowers is used for burns. (Plants for a Future) Other Uses: Green dye made from the flowers. (Plants for a Future) The species was the earliest American species exported to England, and in 1640 was growing in England's King Charles I garden. (Indiana Native Plant and Wildflower Society) General poisoning notes: Early circumstantial evidence of poisoning of horses, sheep, and swine can be found. Experiments on sheep and swine have shown that some symptoms of toxicity can occur, although animals generally refuse to eat the unpalatable plants. Animal poisoning by this plant should be considered unlikely (Kingsbury 1964). (Canadian Poisonous Plants Information System) Not native to NB. (Nature Serve)
