Growing Craspedia: A Complete Profile
By Growing Home Greens Team · July 25, 2026
Craspedia, often called drumstick flower or billy buttons, produces perfectly round, golf-ball-sized yellow flower heads on tall stems, a favorite for both fresh and dried arrangements because the blooms hold their shape and color so well.
Starting it early
Start seed indoors 6-8 weeks before your last frost date, covering lightly, and transplant out after frost danger has passed. It’s slow to reach flower, around 110-120 days from seeding, so an early, unhurried indoor start matters. It’s a tender perennial hardy in zones 8-11; outside that range, grow it as a warm-season annual or bring it indoors over winter.
Getting germination right
Slow, uneven germination is the most common frustration. Give seed the full 14-18 days at a steady 70-75°F before assuming it’s failed, and avoid letting the seed trays dry out during that stretch.
Why it’s worth the wait
Craspedia is worth the patient start if you cut flowers for arrangements. Its everlasting quality means blooms dry naturally on the stem, giving you both fresh bouquets in season and dried material that lasts well beyond it.

Varieties worth considering
- Sun Ball craspedia (Craspedia globosa): Johnny's Selected Seeds bred it specifically for cutting: long, stiff stems that stay straight for harvest, and heat tolerance that keeps the plant producing through a hot summer instead of stalling. It's the variety most cut-flower growers mean when they say craspedia. (source)
- 'Golf Beauty Improved': Breeder Danziger lists this one at a shorter 14 to 18 inches with easy rooting even in northern climates, and it's propagated from cuttings rather than seed. Worth seeking out as a nursery start if a compact plant matters more than growing it yourself from Sun Ball seed. (source)
- Straight-species Craspedia globosa: Select Seeds sells the plain species: grass-green foliage under the same fuzzy yellow globes, without a named cultivar's specific breeding for cut-flower stem length. A reasonable, cheaper option if you're growing it for a mixed border rather than a dedicated cutting bed. (source)
