 Common Name: Snow in Summer

An undemanding groundcover for full sun and poor soil. In other words, a dream come true! Highly valued for its woolly gray foliage, 'Snow in Summer' lives up to its name in late spring and early summer when the foliage is smothered in luminous white flowers.

Though Cerastium can be a rapidly spreading groundcover, 'Yo Yo' has a more restrained, compact habit, making it easier to control. Try growing it in pockets of stone walls, on slopes, or in poor, dry soil where other perennials struggle. It grows especially well in northern zones where summers are cooler and less humid.

Homeowner Growing & Maintenance Tips:

Cerastium should be planted in full sun and poor, well-drained soil. When grown in moist, rich soil, it will spread very rapidly and be hard to contain. The foliage should be trimmed back after the plant is finished blooming to promote more compact growth. It may divided any time during the growing season.
