The flower heads are smaller, no more than 2 ″ in diameter.ĭry to moderate moisture. The hairs on the leaf surfaces are spreading, not appressed. The leaves are egg-shaped, narrower, and 5 to 20 times as long as wide. angustifolia) is a shorter plant, no more than 27 ″ in height. Narrow-leaved purple coneflower (Echinacea angustifolia var. Pink to purplish ray florets, purple disk florets It is tan toward the base, banded with dark brown toward the tip.

The fruit is a dry, wedge-shaped, 4-angled in cross section, slightly flattened, ⅛ ″ to 3 ⁄ 16 ″ long seed chamber (cypsela) with a crown of feather-like hairs attached to one end. They remain on the plant at fruiting time. They are noticeably longer than the disk corollas. The bracts are ⅜ ″ to 9 ⁄ 16 ″ long, hardened, and sharply pointed with a spine-like tip. Each disk floret is subtended by a thin, dry, bract. The disk florets have five petals fused at the base into a yellow to green tube then separated at the tip into five dark purple lobes. The ray florets are pink to purplish or rarely white, 1 ¼ ″ to 3 ⅛ ″ long, ¼ ″ to ¾ ″ wide, and spreading to somewhat drooping at flowering time.

It is 9 ⁄ 16 ″ to 1 ¾ ″ tall and ¾ ″ to 1 9 ⁄ 16 ″ in diameter.

The disk is flattened when young, becoming cone-shaped as it ages. There are 8 to 21 ray florets and 200 to 300 or more disk florets. The flower heads are 2 ½ ″ to 4 ″ in diameter. The outermost phyllaries are bent backward above the middle. The bracts of the involucre (phyllaries) are green, linear to lance-shaped, 5 ⁄ 16 ″ to ⅝ ″ long, sparsely to moderately hairy, and fringed with hairs.
#Purple coneflower height series
The flower stalk is leafless, 3 ″ to 10 ″ long, and covered with scattered hairs.Īt the base of the flower head a whorl of 15 to 30 bracts in three or four overlapping series forming a ½ ″ to 1 ½ ″ in diameter, cup-shaped involucre. The inflorescence is a solitary flower head on a long stalk at the end of the stem. They are short tapered to more or less rounded at the base but otherwise similar to basal leaves. The margins are usually irregularly toothed, rarely untoothed, and usually have a fringe of ascending hairs. The upper and lower surfaces are rough to the touch and moderately to densely covered with stiff, appressed to loosely appressed hairs. They have usually 5, sometimes 3, prominent main veins. They are up to 11 ¾ ″ long and up to 4 ¾ ″ wide, about 1 ½ to 5 times as long as wide. The blades are narrowly to broadly egg-shaped, usually rounded or heart-shaped at the base, and long tapered to a sharp point at the tip. The are sometimes hairless but are usually sparsely to moderately covered with stiff, appressed to ascending, 1 ⁄ 32 ″to 1 ⁄ 16 ″ long hairs.īasal leaves are long stalked, the leaf stalks up to 6 ¾ ″ in length. The stems are erect or ascending, usually brownish-green, round, finely ridged, and branched or unbranched. Zones 4 to 8.Eastern purple coneflower is an erect, 20 ″ to 48 ″ tall, perennial forb that rises on one to a few stems from a short, vertical rootstock and fibrous roots. This species has contributed its unique form to many new hybrids that will be released in the future. The upswept rays of this species make it unique among coneflowers the overall impression is of a rose-purple cup. Size: 1 to 3 feet tall, 1 to 2 feet wide. White Lustre has larger, brighter white flowers than Alba and White Swan. Springbrook's Crimson Star has delicate, deep crimson flowers on sturdy 3-foot stems. Kim's Knee High is an excellent compact selection to 2½ feet with large heads of gracefully drooping rays. Bright Star is a graceful selection with mostly flat rose-pink flower heads. A shrubby, well branched plant with leafy stems and dozens of flowers with flat or drooping rose-pink to red-violet rays. Size: 2 to 4 feet tall (rarely to 6 feet), 2 to 3 feet wide. An important plant in current breeding programs. The plants grow in tight, multi-stemmed clumps with mostly basal leaves. This is an unusual coneflower in that its rays are bright yellow. Size: 2½ to 3 feet tall, 1 to 2 feet wide. laevigata, smooth coneflower, is similar but has smooth leaves. The basal leaves are lance-shaped and covered in stiff hairs. A sparsely branching plant with stout, nearly leafless stems topped with large heads of drooping pale rose rays. Size: 3 to 4 feet tall, 1 to 2 feet wide. USDA Plant Hardiness Zones 3 (possibly 2) to 8. A compact coneflower with spare, lance-shaped basal leaves with stiff hairs and mostly leafless stems topped by 2-inch heads with short (1-inch) drooping rose-pink rays.
