I need help!!! I am so frustrated!!
I cannot remember the name of a tree/plant that I want!!


I took a garden walk in Racine Wisconsin, several years ago. In a yard, I saw what I thought was a small dogwood. When I walked up to it, I saw it had large thorns on it....
It could be perennial, but I thought she said it was a tree, a rather weedy tree, but the name started with an A.

Does anybody out there in Bloggerland know the tree I want??!!!

edit:figured it out and never mind!! It's on the national list of invasives and it's extremely expensive. Normally those two don't work out together, but it must be some sort of grafted invasive. It's Japanese Angelica tree, or Aralia Elata. I'd rather have the dogwood or fringe tree.
