Barbara's buttons is a clump-forming Missouri native perennial which occurs in limestone glades and unglaciated prairie in several counties in the southwestern part of the State. The dense flower heads of this aster (composite) family member are discoid (only disk flowers with no ray flowers). The numerous, tiny, white to pink-tinged disk florets are compacted into solitary, terminal, pincushion-like, dome-shaped flower heads (to 1" diameter) atop long, rigid, slender stems (peduncles) rising to 16" tall. Flowers somewhat resemble some of the cornflowers (Centaurea). Flowers bloom in spring. Narrow linear-lanceolate leaves (to 4" long) mostly appear in basal rosettes, with sparse stem leaves being much smaller.
No serious insect or disease problems.
Limestone rock gardens, border fronts and wildflower/native plant gardens.
