The species was first described in 1818 by Alexander von Humboldt. Its leaves resemble oak leaves, hence the name quercifolia. It grows in Mexico and the Southwestern United States and can assume both a prostrate and an upright bushy habit, bushier forms reaching up to 3 ft. in height. It produces green seed capsules armed with long sharp spines, which, like those of some (but not all) Datura species open by four equal valves. The pale violet, funnel-shaped flowers are less than 2 in. long.
