Coreopsis lanceolata, also called lanceleaf coreopsis or lanceleaf tickseed, is a native perennial wildflower that grows up to two feet tall and features daisy-like, yellow blooms on erect stalks from spring through early summer.The common name tickseed refers to the shape of the plant's seeds, which are curled and brown, and bear some resemblance to ticks
Lanceleaf coreopsis is a low-maintenance, important pollinator plant, and its yellow flowers are especially attractive to butterflies, including the great spangled fritillary (Speyaria cybele) and the hickory hairstreak (Satyrium caryaevorus), which is considered state endangered in Maryland.
Lanceleaf tickseed can be an aggressive spreader, as it self-seeds easily and requires very little in terms of soil moisture or nutrients to the survive; to encourage further blooming through the spring and summer and discourage self-seeding, spent flower stalks can be dead-headed though this may discourage birds that feed on tickseed.
