that I spent five years trying to kill this:
But you have to cut me some slack, in that I did not know what it was! To me, it was just greenery with thorns, big ouchie thorns. Then one spring a couple of years ago I didn't get out there early enough to begin my annual chopping and pulling of it, and a few flowers bloomed. Last year, a few more, and this year, it's getting better! Oh, and according to my Mom, it's Flowering Quince.
