Solanum xanti, known commonly as chaparral nightshade, purple nightshade, and San Diego nightshade, is a member of the genus Solanum. It is native to the Western United States in Arizona, California, Nevada, and Oregon, and to Northwest Mexico in Baja California. [1]

The plant grows in chaparral, oak woodlands, conifer forests, desert Madrean Sky Islands, and other habitats. [2]


Solanum xanti is a perennial herb or subshrub producing a branching hairy stem up to about 90 centimetres (35 in) in maximum height. The leaves are up to 7 centimeters long and are lance-shaped to oval, mostly unlobed except for occasional lobes at the bases of the blades.

It flowers from February to June in the wild, bearing an umbel-shaped inflorescence with many purple-blue flowers up to 3 centimeters wide. The fruit is a green berry 1 to 1.5 centimeters wide. [1]


Varieties of the species include:

  • Solanum xanti var. glabrescens — (endemic to California) [3]
  • Solanum xanti var. hoffmannii — Hoffmann's Nightshade (endemic to California) [4]
  • Solanum xanti var. intermedium — (endemic to California) [5]
  • Solanum xanti var. montanum [6]
  • Solanum xanti var. obispoense — San Luis Obispo nightshade (endemic to California) [7]
  • Solanum xanti var. xanti [8]


The plant is cultivated as an ornamental plant by specialty plant nurseries for planting in perennial border, drought-tolerant and native plant gardens. It grows from sunny locations to dry shade, such as under native oaks. [9] [10] [11]

The plant is deer resistant, due to its poisonous qualities.
