"Durable and dramatic dark purple foliage. This tough, easy growing shrub is a standout with its dark burgundy-black foliage that is especially intense in spring and autumn. The bright yellow flower panicles add contrast in early summer. A durable native that thrives in sun or shade. It's Drought tolerant, deer resistant, and supports pollinator populations, too." -- Spring Meadow Nursery [Diervilla]
