Lanceleaf tickseed covers itself in bright yellow daisies in early summer and grows in ground too poor and dry for most perennials. Coreopsis lanceolata is a native perennial reaching 1 to 2 feet tall and wide in full sun to part sun, hardy from Zone 4 through Zone 9.
Bloom starts in late spring and runs into midsummer, and deadheading extends it. Bees and butterflies come to the flowers, and goldfinches take the seed if you leave the last heads standing.
The foliage is narrow and lance-shaped, forming a low basal clump under the flower stems.
This grows wild in prairies, roadsides, and dry open ground, so it wants full sun and lean, well-drained soil. Rich ground makes it flop and shortens its life. It handles drought, poor soil, and moderate road salt, and it self-sows freely, which suits a meadow or a naturalized planting more than a tidy bed. Deer leave it alone.
