Sow in full sun after danger of frost, or in late summer 12 weeks before ground freezes. Sow seeds evenly and barely cover with fine soil. Keep evenly moist.
How to Grow
Seedlings emerge in 14-21 days. Achillea plants are vigorous growers and benefit from being divided every 2 or 3 years in spring or fall. The stems are often strong enough to be self-supporting, but taller cultivars may need staking. The plants are drought-resistant, and once they are established in the garden, Achillea plants are trouble-free.
These long-blooming, easy-to-grow perennials are popular for both formal borders and informal cottage gardens. They also make ideal fresh cut or dried flowers. Shorter cultivars are suitable for patio containers. Taller cultivars look at home in wildflower meadows.
