The small perennial shrub "Solanum umbelliferum" is known commonly as the blue witch nightshade, sometimes spelled bluewitch. It is one of many species of nightshade in genus "Solanum", which also includes domesticated plants such as tomato, potato, and eggplant. Blue witch has dark gray-green oval-shaped leaves on hairy green stems that grow to a maximum height of one meter. It has bright purple or blue frilly flowers with thick yellow carpels at the center. The flowers close into spherical buds overnight. It bears small round green fruits which turn purple when ripe and resemble tiny eggplants.

Blue witch can be found in chaparral habitat and low-elevation oak woodlands in California and parts of Arizona. It is a tough shrub which can grow in rocky and clay soils and springs up in areas recovering from wildfires or other disturbances. Like most other members of genus "Solanum", "S. umbelliferum" contains toxic alkaloids.
