a volunteer in my garden, I rate it negative because of its wicked thorns. Top of foliage is leathery, dark green and shiny. Underside is "furry" gray. Has a very long tap root. It is a TX native, produces berries and is drought tolerant, so can be appropriate for some gardens, but not for mine.

This tree doesn't seem to be fussy about where it grows. I've seen it growing on a steep, rocky limestone slope with mostly caliche for soil and I've seen it growing in sand and just about every other type of soil. As mentioned in another comment, it would probably be good for xeriscaping since it's a native and drought tolerant. I'm not sure about its lifespan, but it might make a decent tree in full sun with regular care and if you kept the thorny lower limbs trimmed high. It does make a good show when it blooms in early spring, but otherwise, it doesn't stand out and its main redeeming quality is for bird food. It forms dense colonies.

The wood of this tree is quite strong. The bark is somewhat covered with small thorns. It isn't commonly planted in Oklahoma, but it would be great as it tolerates heat and moderate drought conditions. It is a slow grower, though. It makes a great tree for urban settings.
Tree is a xeriscape consideration, being fairly tough and producing a dark blue-black berry which birds and other wild critters feed on.
Sapsuckers seem to be especially fond of this tree with its gummy sap and will work it excessively, which is why I call these trees Gum trees. Most people don't know what these trees are and they are sometimes mistaken for little Live Oak trees when they come up.
Specimens I have examined along fence rows and fields in Bell County are usually small to medium size trees around 30 feet tall with a narrow crown. Specimens growing along the Leon River in Belton are considerably larger. The Texas state record is 80 feet in Robertson County.
There are several varieties of Gum Bumelia in Texas.
This plant has been said to grow in the following regions:
