I need help identifying this plant. It's about to take over.
I think I found it - the best match I could find is acacia berlandieri, common name guajillo tree. I've linked one page about it, but do a search and see what you think.
Here is a link that might be useful: webpage on guajillo
Compare your plant to Prairie Mimosa, Desmanthus illinoensis.
Thanks all for the help, I was stumped on this one.
