Introduction
Snow in Summer (Cerastium tomentosum) is a low-growing, hardy perennial ground cover admired for its silvery-gray foliage and masses of small, white, star-shaped flowers that bloom in late spring to early summer. Valued for its drought tolerance and spreading habit, Snow in Summer is ideal for rock gardens, borders, slopes, and edging. This easy-care plant performs best in sunny locations and well-drained soil.
How to Grow Snow in Summer Seeds
Start Snow in Summer seeds indoors 6–8 weeks before your last frost date, or direct sow outdoors in early spring or fall.
Use a well-draining seed-starting mix.
Sow seeds on the soil surface and lightly press them in; do not cover deeply, as seeds need light to germinate.
Water gently to keep soil lightly moist.
Maintain temperatures between 60–70°F for optimal germination.
Seeds typically germinate within 7–14 days.
Once seedlings emerge, provide bright light.
Transplant seedlings when they have 2–3 true leaves.
Harden off seedlings before planting outdoors.
Space plants 8–12 inches apart in full sun.
How to Care for Snow in Summer Plants
Water young plants regularly until established; mature plants are drought tolerant.
Grow plants in poor to average, well-drained soil; avoid rich or wet conditions.
Do not overfertilize, as excess nutrients reduce flowering and encourage legginess.
Snow in Summer thrives in full sun and tolerates heat and light frost.
Shear plants lightly after flowering to maintain shape and encourage dense growth.
Mulch lightly with gravel or coarse material to improve drainage.
Watch for root rot in poorly drained soils.
Divide plants every few years to maintain vigor and control spread.
