Fouquieria is a small genus of shrubs and small trees, mostly restricted to the Sonoran desert of southwestern USA and northwestern Mexico, including large part of the state of Sonora, and Baja California.
Most species are drought deciduous and drop their leaves if they lack water. They might then look quite dead.
The flowers are white,yellowish-orange or bright red depending on the species but they generally come at the end of the branches.
All these species are extremely heat resistant, and they need full sun. Most of them will take a limited amount of frost, the most cold resistant is the Ocotillo (Fouquieria splendens), that has been reported surviving 0°F (-17°C), although many sources report it hardy only to 20°F (-7°C).
The most popular species in the trade are F. splendens (Ocotillo), F. columnaris (Boojim Tree), F. macdougallii, F. purpusii, and F. fasciculata. Each has their own unique characteristics that are sought after by collectors.
