Description
Shrubby St. John’s Wort is a dense, rounded native shrub with small blue-green leaves and bright yellow flowers with showy stamens that bloom in mid to late summer. The flowers provide an important nectar source for pollinators during the heat of summer when fewer shrubs are in bloom. This adaptable species tolerates drought, poor soils, and urban conditions once established, making it a reliable and low-maintenance addition to native plant landscapes.
