Title: Does goldenball leadtree (Leucaena retusa) have thorns?
Answered by: Nan Hampton
QUESTION:
I have a plant that I am told is a native Texas plant, but the person I got it from could not remember its name. They said it was very hardy and drought tolerant. It looks a little like goldenball lead tree, but it has a few thorns. Do leadball trees have thorns?ANSWER:
The only reference I could find that says Leucaena retusa (goldenball leadtree) has thorns is from the University of Florida IFAS Extension, but then another publication from the University of Florida says it has NO thorns. I think that the first one that says it has thorns is a mistake. I think that they just left the "no" out of the text.
Perhaps the plant is Acacia farnesiana (sweet acacia). Its leaves look like those of the goldenball leadtree (although smaller), it has yellow blossoms that are similar and it does have thorns.
If you don't think that this is the tree you have, send us photos and we will do our best to identify it. Please visit Mr. Smarty Plants' Plant Identification page to read instructions for submitting photos.
