plant sale text: Hairy St.John's-wort is a native perennial that occurs in moist and wet pine flatwoods, savannas, ditches, and bogs in the southeastern Coastal Plain. It has small, yellow pinwheel-shaped, five-petaled flowers throughout the summer. Hairy St.John's-wort is named for the dense, tiny hairs covering the stem and leaves. This species prefers moist to wet soil in full sun and would be a perfect addition to a sunny bog garden.
