Garden coreopsis

Coreopsis lanceolata, commonly known as lance-leaved coreopsis, lanceleaf tickseed or sand coreopsis, is a clump-forming perennial herb of the family Asteraceae, native to the central and south-eastern United States, where it grows in dry, sandy or rocky open ground, prairies, glades, road verges and disturbed sites, and is widely naturalised elsewhere in North America and overseas as a garden escape. The plant typically grows 30–60 cm tall, forming a basal rosette and producing erect to ascending, slender, glabrous to sparsely hairy stems that are mostly leafless above. The leaves are largely basal and on the lower stem, lanceolate to oblanceolate or spatulate, 5–20 cm long including the long winged petiole, entire or sometimes with one or two basal lobes, dark green and somewhat fleshy. The flowering heads are showy, 4–6 cm across, borne singly on long naked peduncles; each head has 8 broad, bright yellow ray florets, each ray with a notched, 3- to 5-toothed apex, surrounding a yellow disc of tubular florets. The involucral bracts are in two distinct series. The fruit is a small, dark, winged achene with two short awns. Flowering occurs in late spring and early summer.
