Open spreading tree or large shrub with deciduous fine-textured light green foliage and fragrant yellow flowers (actually, puffballs of yellow stamens) in winter and early spring. Branches are covered in sharp thorns. Its natural habit is multi-trunked, growing about as wide as it is tall. This species is native to central and southern Texas, through the U.S. southwest, Mexico, and Central America. I've learned that it is considered a nuisance tree by those who manage natural areas, because its saplings already possess a lot of ability to puncture shoe soles. We'll be pruning ours up as it reaches for the sky, to keep those spines away from tender skin. Our tree has grown very fast, and after producing just a few flowers in its first spring, it lit up the garden with a golden display the following year.
