The Shasta daisy is a classic hardy perennial (Zone 3) with large single white flowers and a golden yellow center. Shasta daisies tend to bloom in clumps from 45-75cm (18-30” tall) and can spread easily to 61-91 cm (1-2’ wide). Shasta daisies return every spring or early summer and bloom until early fall. They are easy to grow and are adaptable to most soil types. Bloom well in full sun or light shade. They are trouble free and tolerant of heat and drought.
If you seed directly, expect blooms the following spring after one season’s growth. Start seed 8 to 10 weeks early indoors. Germination requires 14 to 21 days at 20 C (70 F). Grow under bright lights at a cooler temperature of 15 C (60 F) before hardening off and transplanting outside to a sunny spot. Seed can also be directly sown in the garden in May and again in mid-August to early September for flowering in the following year.
