Description
Solanum douglasii is a perennial herb or subshrub approaching 2 metres (6+1⁄2 ft) in maximum height. The stem is coated in short, white hairs. The leaves may be up to 9 centimetres (3+1⁄2 in) long and have smooth or toothed edges.[2]
The inflorescence is an umbel-shaped array of flowers with star-shaped white corollas up to a centimeter wide. There are generally green spots at the bases of the corolla lobes. The yellow anthers are a few millimeters in length. Flowers may be seen blooming throughout much of the year.[2]
The fruit is a spherical black berry up to 1 cm (1⁄2 in) wide.[2][3]
Distribution and habitat
It is native to the northern half of Mexico and the southwestern south-central United States. Its habitat includes scrub and woodland.[2]
Uses
Many species in the genus are toxic.[2] Native Americans used the juice of the berries medicinally, and the Luiseño used it as dye for tattooing.[4]
