Looks somewhat similar to C. corymbosa, but the leaves aren't quite right.
After I presented to a group of students at Founders Academy, I stopped by this little park for an early dinner sandwich. It's a bummer of a park -- the creek has been channelized with concrete. :(
There was a control burn in this part of the park, and what's coming up is wonderful. :) And, of course, it's great to attract various bugs too.
