Snow-in-Summer Seeds – White Perennial Ground Cover

A Blanket of White Flowers for Sunny Spaces

Snow-in-summer (Cerastium tomentosum) is a perennial ground cover that produces a blanket of white flowers reminiscent of freshly fallen snow. Grow it from seed to bring a soft, flowering carpet to a sunny garden.

This drought-tolerant plant is best suited to cool, dry climates with moderate temperatures. Choose its location carefully: good drainage and a less humid environment are important to its success.

Plant Highlights

• Botanical name: Cerastium tomentosum.

How to Start Seeds Indoors

1. Start seeds indoors 6–8 weeks before your planned outdoor planting date.
2. Fill small pots with sterile seed-starting mix.
3. Scatter seeds lightly over the surface and press gently into the mix. Do not bury them; light is needed for germination.
4. Keep the seed-starting mix moist until germination.
5. Before planting outdoors, harden off seedlings gradually over 10–14 days.
6. Plant in a permanent full-sun position with excellent drainage.

Choose the Right Growing Conditions

Match this ground cover to a cool, dry garden setting rather than a humid site. Although established plants are drought tolerant, seeds need moisture during germination. Avoid a planting area where water remains around the roots.
