Horticultural Information
Intro: Erect annual (rarely a biennial) of open woodlands, roadsides and disturbed areas.
Stems: Stems slender, branched above, ribbed and with short hairs pressed upward against the stem..
Leaves: Leaves alternate, linear to spoon-shaped, 1/2-4 in.long, mostly entire and rough-hairy (basal leaves, usually withered by flowering, toothed near the tip).
Inforescence:
Flowers: Daisy-like compound flowers (heads) at ends of branches; heads 1/2 in. wide, with 40-100 threadlike, white to pale pink ray florets encircling the yellow center composed of tiny, tubular disk florets; surrounding the saucer-shaped base of the head are several whorls of hairy, narrow, green bracts.
Fruits:
Comments: The similar E. strigosus var. calcicola is a rhizomatous perennial of shallow soils over calcareous rock; its stem leaves are usually smooth, except along the midvein and margins.
Height: 1-4 ft.
