Hi... for the sake of looking it up for info...another name to look at is "purslane"... look up for images and descriptions

Jaynine, Thanks for the help! :)

dig a small hole.. and find out how much water is actually getting into the root zone ... is the tree properly mulched??? next time skip the fert in the hole ... dont fixate on that now... insure PROPER water through dormancy .... it is NOT uncommon .. on transplanted trees to show high signs of stress ... during it first or second summer after transplant .... perhaps just a survival mechanism... reducing leaf count to the truncated root system ... as long as they dont all turn brown and fall off 2 months before they are supposed too ... i would give it high odds of returning.. subject to the pix ... and even early dormancy.. wouldnt be fatal ... with a redbud ... starting with a smaller tree .... would probably have avoided this... they just adapt faster on the root to leaf ratio .... good luck ken

I think I found it as Rosa hugonis - Father Hugo's rose. But, this one is very much larger than 6'
