- Description
-
Snow-in-summer is a low growing perennial that will form a 6" tall mat of attractive narrow leaves. Spreading will occur by underground runners. In late spring to early summer, stems with showy star-shaped white flowers will protrude 8-12" above the ground-covering mat. Each stem may produce up to 15 blooms. The numerous blooms form a snowy-looking carpet of white, hence its common name.
Self-seeding will occur if the spent blooms are not removed. Divide every few years in the spring or fall. Propagation can also be done from cuttings in early summer. Pruning should not be done in the fall, wait until spring.
Insects, Diseases and Other Plant Problems: Root rot can occur in locations where good drainage is not provided. It does not tolerate foot traffic. It can be an invasive plant in locations with cooler summer climates. It is a short-lived plant that may result in dead patches in a covered area. Does not perform well in climates with high humidity or in a location with insufficient sunlight.
