Hairy St. John's-wort is a upright, softly hairy perennial that bears cheerful yellow flowers in mid to late summer and grows naturally in shaded woodland edges and hedgerows. It prefers moist, well-drained soil in partial shade and requires minimal care beyond cutting back old stems in early spring. This plant has a long history of medicinal use and is a great addition to a wildlife or cottage garden.
