Black dalea is small mounding shrub, 3-4 ft. tall and as wide. Gray foliage is comprised of pinnately compound leaves having 13-17 leaflets that will drop during periods of drought stress. Deep purple flowers occur in round heads in spring and intermittently from summer to fall.
Black dalea is native to dry areas on rocky hills and plains in desert regions of Texas, New Mexico and Mexico. This is an open and delicately branched shrub that works well in dry stream beds and small garden spaces in Southwestern style gardens. The cultivar, D. f. ‘Sierra Negra’ produces intense rose-purple flowers and can reach 3 ft. tall and 5 ft. wide.
