Craspedia

Craspedia globosa

Billy button, also known as Billy balls, or drumstick, boasts striking one-inch globes in a brilliant shade of yellow. Native to New Zealand, Australia, and Tasmania, it is classified as a half-hardy annual in the United States. These flowers typically grace your garden with their presence throughout the summer. Billy buttons can reach up to 24 inches in height. They are hardy perennials in USDA Zones 8 through 10 and suitable to grow as annuals in USDA Zones 3 to 7. They are known to be deer-resistant and display good tolerance to drought conditions. Growing craspedia globosa provides a delightful addition to your garden, attracting bees and butterflies with its unique beauty. Water your plants only when the top layer of soil is dry. Craspedia is not a heavy feeder, but you can apply a slow-release fertilizer during the growing season, or add compost or aged manure for healthy growth and to suppress weeds. Craspedia is a tough plant that resists most pests and diseases, but watch out for spider mites, snails, and slugs. A fun craft to do with craspedia is to dry the stems upside down (to keep the stems straight). Once dried, blooms can be spray-painted different colors and then used in a variety of craft projects or arranged in a geometric display.
