Snow in Summer (P)
Cerastium tomentosum
Perennial. Hardy in zones 3-7.
Start inside 6-8 weeks before planting out. Cover seed lightly and provide average soil warmth of 18-21°C (65-70°F). Should germinate in 5-15 days. May be direct seeded outside in early spring or late autumn. Transplant after last frost into a full sun location, 12-24 inches apart. Grows well in part-shade but will not bloom as heavily. May become invasive if not kept in check. Shear after blooming to keep plants tidy. Divide in spring when plants are too large. Grows well in hot, dry sites and poor soil.
