Bluewitch Nightshade (Solanum umbelliferum) is a native shrub Solanaceae (Nightshade) family that is widespread in California in various habitats and vegetation communities, at elevations from sea level to 5,200 feet. The stems are densely hairy and branched. The leaves are grey-green, elliptical to oval, and typically smooth edged. The flower is blue to purple in color, consisting of five petals fused together, with contrasting yellow anthers. The fruit is a sphere 12-14 mm in size. Its habit is mounding or sometimes vining, often found climbing up through more woody shrubs. All parts of the plant are toxic to people and some animals. However, it is very attractive to insects. If given occasional summer water it will stay leafed-out and may even continue to flower. If allowed to dry it will be summer deciduous. This is a very tough, hardy plant that will survive on neglect.
