This odd little plant sprouted from mulch (I think) and for the life of me...I have no idea what it is. I've ruled out any sort of Mimosa or Pride of Barbados....since the flowers are tiny, yellow and attached to the stem. Or would I call it a trunk at this point? Its been too dadgum hot around here to even take a photo down to my favorite nursery (Rainbow Gardens.) The blooms actually sort of look like sweetpeas and this "thing" is growing about an inch a day! I swear! Well...its a fast grower, anyway...lol. Anyone care to take a guess? Oh and it has soft thorns on the trunk as well...
