A florist favorite, craspedia adds intrigue to the garden with clusters of sunny orbs and is dazzling in cut or dried arrangements. The blooms may look delicate, but the plants are tough, tolerating drought, heat, and heavy, poor soil. This pollinator-attracting flower is commonly known in its native countries of New Zealand and Australia as Billy buttons. Perennial in USDA zones 8–11 and warmer, often grown as an annual. In perennial areas, good drainage is required in winter.
