Desert Thorn-apple (Datura discolor) is a low lying, shrub like annual. Its foliage is light green, and its stalks have conspicuous purple stripes. The ovate-shaped leaves can be whole or toothed. The flowers open for only one night and wither the following day. Its seed capsule is thorny like most other Daturas, and can be up to 3 in. long and 2½ in. in diameter. The species' natural distribution area stretches from Mexico to the Southwestern U.S. and the Caribbean Islands. It is a sun-loving plant which does well underneath overhanging eaves that can protect its flowers from damage by rainfall.

WARNING: The leaves and seeds of Desert Thorn-apple (Datura discolor) are sources of several alkaloidal drugs, some of which have narcotic properties. They are poisonous to people as well as to cattle, horses and sheep. Some local communities have banned the cultivation of Datura species.
