Hypericum perforatum

This sunshine-yellow flowering herb is often used in landscaping and grows up to three feet tall. Has well known medicinal uses as well. Well-suited for pollinator habitats. 

Direct seed in early spring or transplant into the garden after all danger of frost has passed. St. John’s Wort benefits from cold stratification. Requires light to germinate so gently press seeds into the soil without covering them. It will need full sun to partial shade and well-draining soil. Water well to ensure good germination. Once germinated, St. John’s Wort will need at least an inch of water per week. Typically grown for leaves and flowers. Perennial.
