Retama (Jerusalem Thorn) trees are quite numerous in the South, South Central and West Texas Regions. Unfortunately, this one was not blooming when I took the photo. (San Antonio, Tx.)

Retama (Jerusalem Thorn) blooms are especially nice when the sunlight backlights them. The blooms are bright yellow and red. In October, it has almost stopped blooming.(San Antonio, Tx.)

A beautiful tree, beautiful flowers, and sharp thorns. It grows easily in this area, grows to about 25 feet tall. Blooms in May in Santa Fe, Texas.

A retama (Parkinsonia aculeata) tree in full bloom with its light green leaves is a beautiful sight. Shown at the end of April.

The retama tree (Parkinsonia aculeata) provides a nice accent if grown in a location where it isn't a nuisance. Shown at the end of April.
