Sorry I didn't see this until now beatlerat. I cut holes on the underside of mine in an X and pushed through the x with the stick and reinforced then with the hot glue and sepal petals. It seems to work great...I've had my plant out since I posted it and my kids and dogs bump it frequently without issue. I had about 5 coats on mine as well. Hope that helps.
I thought of using a wire too and making it look tendril like at the edge, but it didn't seem to need it.
