Surviving neglect, Solanum umbelliferum (Bluewitch Nightshade) is a rounded to spreading, evergreen to deciduous shrub boasting a profusion of small umbels of blue-purple flowers adorned with a cone of prominent yellow stamens. Though the main bloom period is spring and summer, some flowers will occur most of the year. The flowers are frequented by bumblebees and a few other bee species. Borne on slender stems, the frilly blossoms close into round buds overnight. They attract insects and give way to small round green fruits which turn purple when ripe and resemble small eggplants. Birds feast on the fruit. The blossoms stand out nicely against the foliage of simple, oval, gray leaves. The leaves are summer deciduous if the plant is not given enough moisture. Solanum umbelliferum is native to Chaparral and Juniper-Oak Woodland plant communities from northern California to Baja California and east into Arizona, where it can be found growing on dry rocky slopes and canyons from sea level to above 5,000 feet. Bluewitch Nightshade is a tough, hardy shrub that can grow in rocky and clay soils and springs up in areas recovering from wildfires or other disturbances. Deer resistant, Bluewitch Nightshade is a great plant for a dry rock garden, perennial border, or as a container specimen.
