Helenium

Helenium autumnale ( Fall Helenium )

A fast growing, perennial, forming large, dense clumps, reaching up to 6.5 x 2.5 ( rarely over 4 ) feet, that is native to wet prairies and bottomlands of North America ( from Vancouver Island to Kamloops, British Columbia to Drumheller, Alberta to southern Saskatchewan to Manitoba to Kenora, Ontario to Thunder Bay, Ontario to Tobermory, Ontario to far southeast Quebec and northern New York State; south to northern California to central Texas to northern Florida ). It is critically endangered in Alberta. In the Windsor/Essex County, Ontario region; it was considered uncommon in southern Essex County during the 1800s. It was abundant at Detroit, Michigan as well as on the Ohio shore during presettlement era. It is an excellent plant for color at the back of a landscape border. It is an important host plant for Dainty Sulfur Butterfly.
The toothed, lance-shaped to narrowly-oblong leaves are up to 6.5 x 2 inches in size. The foliage is mid-green.
The yellow flowers, up to 2 inches across, are borne in large clusters from mid-summer into early autumn. Each "daisy" has up to 20 reflexed petals.
The flowers attract butterflies.
Hardy zones 3 to 7 in full sun to partial shade on well drained soil. They prefer consistantly moist soil but will tolerate drought with less vigor. Fall Helenium will tolerate poorly drained, wet sites. Deer and rabbit resistant, insect pests and disease problems are rare but may include rust and powdery mildew.
For bushier, sturdier plants, cut or pinch plants back half way during very early summer. Cut back after flowering to encourage more flowering.
Propagation is from seed, basal cuttings and division.
