Thevetia thevetioides (Giant Thevetia) - A small, open, evergreen tropical tree from Puebla and Oaxaca Mexico that grows typically as a large shrub in Southern California where it reaches to 15 feet tall and is sparsely foliaged with attractive dark green leaves at the branch tips; the linear leaves are 3 to 6 inches long by inch wide with the edges rolled underneath and pronounced veins on underside of the leaf. From mid-summer to late fall this plant produces showy 4 inch wide bright yellow funnel-shaped flowers. Plant in full sun and give regular irrigation in the summer. Hardy to 27 F. The specific epithet thevetioides means "similar to the Thevetia" as reference to the similarity of this plant with the plants in the C.S.Kunth (1819); genus Thevetia. This name makes more sense now that the original name, Cascabela thevetioides, that German botanist Carl Sigismund Kunth (1788-1850) first used to describe this plant in 1819, has been resurrected. We continue to use the name Thevetia thevetioides until this name change gains more general acceptance. The name Cascabela comes from the common name "Cascabel" used for this plant in Mexico. Other common names used for this plant include Giant Helveti, Giant Lucky Nut and Be-still Tree.  The information on this webpage is based on research conducted about this plant in our nursery library, from online sources, as well as from observations made of it as it grows in the nursery in containers, in the nursery's garden and in other gardens where we have observed it growing. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Thevetia thevetioides.
