Size and method of spreading:

Snow-in-summer is a colonizing ground cover that grows up to six inches high, but when in full flower may reach up to ten inches. Colonizing ground covers produce underground stems that spread out horizontally and shallowly, produce roots and then send up new shoots. Snow-in-summer is generally easy to manage, although some colonizers can be strong growers and have the potential to grow aggressively.

Native geographic location and habitat:

It is native to Europe.

Leaf description:

The small, opposite leaves are narrow and are densely covered with white hairs which gives them a silvery appearance.

Flower description:

Small, white flowers are produced on upright stems in late spring. The petals of the flowers are notched.

Fruit description:

The fruit are small, dry capsules and not ornamentally important.

Plant care:

Snow-in-summer needs full sun and good drainage. It does well in low fertility, dry, or shallow-rocky soil. When flowering ends, use a string trimmer to remove the spent flowers for appearance sake. In very humid conditions, the foliage may decline. Trimming the foliage back will encourage new growth.
