Shasta daisies deliver the clean white-and-yellow daisy look everyone recognizes. Easy, long-lived, and excellent for cutting. "Becky" is the landscape standard — tall, sturdy stems that don't flop.
Sun: Full sun. Water: Moderate. Zones: 4–9. Height: 1–3 ft. Bloom time: Early to mid-summer.
Plant in well-drained soil in full sun. Deadhead to prolong blooming. Cut back by half after flowering for a second, smaller flush. Divide every 2–3 years — center dies out otherwise. "Becky" is the most reliable tall variety.
常见问题
01 Why is my shasta daisy dying out in the middle?
Center-dieback is the classic shasta daisy problem — the oldest crown dies while the edges stay vigorous. Divide every 2–3 years in early spring: dig the clump, discard the dead center, and replant the healthy outer sections.
02 Do shasta daisies come back every year?
Yes — reliable perennial in zones 4–9. "Becky" is the most dependable tall variety; shorter cultivars are sometimes shorter-lived (3–4 years before needing replacement). Division prolongs their useful lifespan.
03 When do I cut back shasta daisies?
Deadhead throughout summer for longer bloom. Cut the whole plant back by half in late July for a smaller second flush. In fall, cut stems to 6 inches after hard frost. Leave some winter interest by cutting in early spring instead.
