Common pearlbush (Exochorda racemosa) is a deciduous flowering shrub valued for its abundant early spring blooms and graceful, arching form. In mid-spring, it produces masses of pearl-like buds that open into bright white, five-petaled flowers, creating a striking display that often covers the entire plant. This species performs best in full sun to partial shade with well-drained soils and is adaptable to a range of site conditions, including moderately heavy soils. Once established, it requires minimal management and exhibits moderate drought tolerance.
