- Description
-
Large-Flower Tickseed is a native perennial wildflower in the aster family. It has very showy bright yellow flowers and blooms from late spring to late summer. Deadhead the spent flowers to prolong the blooming season. It is clump-forming and grows 1-3 feet tall and wide.
It prefers a sunny location in well-drained soil in the drier portion of the garden. Its preference is for sandy or rocky soils but can adapt to clay soils if it's well-drained. Large-Flower Tickseed may not always be reliably perennial but will reseed itself in the garden. Clumps can also be divided in early spring.
Use in the border or rock gardens and in swaths to provide a long season of color.
