This thorny, deciduous small tree or large shrub is native to the Southwest. It produces fuzzy yellow 2-inch long flower spikes from April to June, followed by fascinating coiled seed pods. Screwbean mesquite has a shrubby, multi-trunked form, and will require careful pruning to develop a walk-under canopy. The shaggy bark is a wonderful feature on older trees. It grows best in deep, well-drained soil and full sun exposures. It will accept ample water but is considered very drought tolerant. This plant is very tough and carefree, although mistletoe and scale infestations are possible.
