THEVETIA TREE
Thevetia mistakenly shaped as an Oleander bush (above).
Thevetia properly shaped as a small, multi-trunk tree (below).
The Thevetia tree, also known as "Lucky Nut," is very common throughout the southwest landscape. It has long, waxy green leaves and bright yellow trumpet-shaped flowers that bloom all year-round. Their flowers so closely resemble Oleanders that they are commonly mistaken for a yellow variety of the shrub.

But Thevetia is, in fact, a multi-trunk tree that provides an umbrella-shaped canopy of shade. They are so heat-tolerant that they are often planted against walls that get too hot for other plants and trees to survive.
