Bluewitch Nightshade

Solanum umbelliferum

Blue nightshade is a rounded, spreading shrub growing 2-3 ft high and about as wide. The greenish, woody branches spread into densely haired stems. The grey-green leaves are smooth, shiny and oval-shaped. The blue to purple flowers have five fused petals, with contrasting yellow pollen stamens in the center. The eggplant-like fruit is dark purple and 12-14 mm in size.



Basic Information

  • Member of the Solanaceae (Nightshade) family

  • Shrub or sub-shrub

  • Drought deciduous and sometimes winter deciduous

    • Loses leaves under specific conditions


Habitat

  • Native to the California and Oregon Coast Range foothills and valleys, south to Baja California, and east to Arizona

  • Commonly found in chaparral, sage scrub, grassland, and woodland ecosystems on dry, rocky slopes, canyons and mesas


Ecological Role

  • Fruit eaten by birds

  • Flowers frequented by bumblebees and a few other bee species

    • This is a nectar-less flower, meaning that the pollen provides no immediate energy, so bees foraging on these flowers must intermittently visit nectar-bearing plants


Reproduction

  • Blooms from March to July


Alternative Names

  • Bluewitch, Barba De Chivo


Historical Uses

  • Native people ate the fruit; preparation is undocumented so it is not recommended you try to consume them


Additional Information

  • The flowers close at night to protect the pollen. This process is called nyctinasty.

  • All parts of this plant are toxic to humans, as well as a number of animals
