Hi Leo, all, Here is a picture; it is about a 7 foot tree, the trunk at the bottom is around 1-1/2 inch, kind of leggy. The nursery label only says "desert acacia" which is not really very descriptive. I added a picture of the leaves in case anybody can recognize it. This acacia has no thorns, and the leaves kind of close up at night. Here are the pictures. I am not sure if now is a good time to chop down this Acacia. When I chop it, I will likely do it close to where the trunk splits. It will be a sleep tree still, but I am ok with that.
The reason I like acacia, is because one of the first bonsai I saw in person, and which was very inspirational was an Acacia in a restaurant in Merida, Venezuela, probably about 12 years ago, that one looked like an acacia, but likely a different species than this one; the leaves were a bit more greenish, the bark was dark as well, but I believe it had thorns.
