Texas Umbrella Tree/Chinaberry


This is another great desert tree that should be considered when contemplating the addition of shade trees to the yard, the Texas Umbrella Tree or the China Berry Tree, Melia azedarach ‘Umbraculiformis’. These trees are native to Australia and southern Asia. The name of the tree comes from its upward-arching branches and drooping foliage.

The tree is extremely adaptable to many different areas and conditions. Widely dispersed throughout the southern United States, from the east coast to the west (even Hawaii), this tree provides excellent shade and has wonderful ornamental qualities. It is a fast grower to 40 feet, sometimes taller. Spread is roughly 20-25 feet. Size however is greatly dependent on planting location. Planted in dry areas at elevation the tree will not generally grow as fast or as tall as areas where humidity is high and elevation is below 1,500 feet. That said the tree is also somewhat drought tolerant but does look best with fairly regular water. Planted near lawn areas should eliminate the need for direct water.

As for soil conditions that is slightly more difficult to nail down in that the tree will grow in wet conditions as well as dry. Texas Umbrella produces masses of purplish, fragrant, star shaped flowers that are very attractive. It will also take some shade so its OK to try these in a somewhat shaded area. Make sure they do get at least 6 hours of full sun.

There are some major drawbacks that should be noted and seriously considered before planting. The Texas Umbrella reseeds itself easily. This can provide quantities of unwanted seedlings that require a certain level of effort to control. Texas Umbrella is invading and disruptive in certain areas. It is reported to be invasive and disruptive in 11 states that included Hawaii and Texas. The tree is not considered invasive according to the California Invasive Plant Council.

There is some thought that these might not make the best landscape trees based on the fact that no too much will grow under them and because they have a relatively short life span. Also note that each and every part of the Texas Umbrella tree is poisonous. Leaves, bark, berries and seeds. Eating as few as 6 berries can result in death. Be very minful of this if you have young children around the house. Even birds that eat too many seeds have been known to become paralyzed.

Is this even worth the risk you might ask? That seriously depends on your point of view. If you are looking for a uniquely structured and very colorful accent tree then these negatives just might be worth the risk.

David: I appreciated this post on the Texas Umbrella Tree. My neighbor recommended it based on his experience with it in California (I am in Tucson). I am looking for potential alternatives to the Mesquite that is likely to go in my back yard. I was almost sold on it until I read here that all parts of this tree are toxic; I do have a dog who already has GI issues and will eat almost anything (though he stays away from neighbors' oleanders, thank God), so your inclusion of that information on this tree is really appreciated! Thanks!
