Botanical name: Datura discolor Family: Solanaceae (Potato family)
Synonyms: Datura thomasii
Synonyms: Datura thomasii
Desert Thorn-Apple is an upright or low-lying shrub
that can grow to 4.5 feet tall. The ovate-shaped leaves can be entire
or toothed. Its leaves are light green, and the stalks have prominent
purple stripes. The species name discolor, meaning "various colors,"
refers to its trumpet-shaped flowers, which are white in the bell, and
pale to dark violet from the narrow part of the bell to the base.
Desert Thorn-Apple has the largest flowers, up to 17 cm in diameter, of
any Datura species, which makes it attractive for garden cultivation.
The flowers open for only one night and wilt the following day. Its
seed capsule is thorny like most other Daturas, and can be up to 7.5 cm
long and 6.5 cm in diameter. It is a sun-loving plant which does well
underneath overhanging leaves that can protect its flowers from damage
by rainfall. Desert Thorn-Apple is native from Mexico to the
Southwestern U.S., and the Caribbean Islands.
