Snowdrop anemone is a hardy, low-growing perennial, native to Europe, which blooms prolifically with delicate, 5-petaled, white flowers. Tolerant of shade, it is best grown in masses among trees and shrubs. The best show of flowers is in April, but it continues blooming sporadically until summer's heat, when it puts out a few more blooms in September. Even when not in bloom, the fine-textured divided leaves are attractive.
