Parkinsonia aculeata, Palo Verde is a deciduous shrub or tree. It grows rapidly at first, then slows, eventually reaching 15 to 30 feet. In Spring, it blooms with numerous yellow flowers in long clusters. Sometimes it intermittently blooms throughout the year in warmer climates, and has a bright green trunk.
Mexican Palo Verde is extremely tolerant of alkaline soil, and is xeric once established. It needs to be staked the first several years, and trained the way you'd like it to grow.
