Description

This striking nightshade is native to much of Baja California and northwest Mexico. A small population grows in Pima County, Arizona. It is absent from California. It grows as a rounded, open, shrub to about five feet, with nearly white branches and foliage. Unusual for a nightshade, the plant is protected by stout thorns on the branches. In spring, large purple flowers appear which stand out dramatically against the light green foliage. Baja nightshade is said to be damaged by frost at about 25F, but I have not seen this in a specimen that I have kept in a pot for several years in my San Jose garden. Plant this desert species against a south facing wall, or under a tree where it will receive overhead protection but not shade. Baja nightshade is drought tolerant, but like many desert species it responds well to occasional summer water.
