Sweet woodruff (Galium odoratum)

Quick facts and care essentials

• Evergreen perennial
• Zones 1-6, 15-17, 31-43
• Partial to full shade

Spreading to form a mat of 6- to 12-inch stems bearing whorls of dark green leaves, sweet woodruff is a good choice for covering the ground under trees and tall shrubs. Clusters of tiny white flowers appear from spring into summer. May spread too rapidly in rich soil; dig or cut back excess growth. Space plants 1 foot apart.
