Gardeners' Notes:

This tree is very invasive in West Texas. It doesn't get that tall and I hear they drink a lot of water. An ugly tree, especially in the winter months. Very hard to kill. You can cut it to the ground and it will grow back vigorously with multitrunks. They can be pruned to look more tree like, but unpruned mesquite trees are very bushy. They are prone to getting dead branches. I have a lot of these trees on my property, and it's not uncommon to step on a mesquite thorn and it go through the shoe into the foot.

Someone erroneously stated Honey Mesquite as the most abundant plant in the desert of the southwest.
I am a naturalist guide in the Colorado desert, For the Records; That distinction goes to Larrea Tridentata, more commonly known as Creosote Bush.

The most common shrub or small tree of the Desert Southwest, mesquite restores nitrogen to the soil. The bean pods can lie dormant for forty years and can be viable. The bean pods have been used by wildlife (especially deer), livestock and humans as a source of food. Believe it or not in late summer, it is estimated that over 75% of a coyote's diet is comprised of mesquite beans.

Native Americans counted upon the mesquite pod as a main source of food making ground meal called pinole, tea and syrup. The bark was employed in the production of medicines, fabrics and basketry. The yellowish-gold mesquite flowers produce a fragrant honey which is a favorite of bees and other insects.

Mesquite comes in a close second next to ironwood as the best firewood of the dese... read more

It's a wonderful tree, not a native, but it's been such a part of my life, it wouldn't be south Texas without it. It does make a mess in a yard, and you better not go barefoot under it. It is drought-resistant. In spring when the new leaves come out, it looks like a mound of lime green feathers!

Indians in the Southwest ground the seed pods into flour for baking. Has a sweet taste. Wonderfully drought tolerant tree.

Salt-tolerant tree native to the southwest U.S. This is a wide spreading, drooping ree with an umbrella-shape to it. It needs pruning to train as a standard shade tree. It is a fast grower. The stems are thorny. The wood is renowned as a charcoal for flavoring bar-b-que meats!
