Gardeners' Notes:

I grew up with a very old specimen of this tree in my front yard. It was a long lived specimen which had survived since before this area of Texas was settled.

It was a fantastic tree for most of the year. It had attractive sweet smelling flowers in the spring. Most of the year it provided dappled shade that didn't inhibit the grass growing underneath. Later in the year interesting long bean pods hung from the tree. In the winter it shed all it's leaves letting the winter sun shine onto the house. All the neighborhood children found it an ideal climbing spot.

As an adult I've learned more positive attributes. It was fertilizing the grass that surrounded it, the beans are actually a healthy food, and it may even have been pulling additional water to the surface... read more

In north Florida, zone 9a, this plant has performed poorly and/or died for me in three different locations. Acacias, Jerusalem thorns and desert willows are growing well in at least one of these sites.

Honey mesquite is a common shrub of the Mojave and Colorado deserts. It is a plant with a very deep root system (up to 150') that can extract water from the water table. It often grows in dense thickets near desert washes, but also occurs at the base of sand dunes and other areas where the water table is not far below the surface. Honey mesquite has long, flattened pods and elongate clusters of tiny white flowers. The large seeds are edible and are staples in the diets of desert animals.
