Sweet mount. Mine bloomed this spring with a 2nd bud starting but I used twine, I know, ugly, but I'm learning. I learn a lot from great pictures like yours. Thanks.
Once it attaches to the mount, you can remove the strings, but do give it a chance to establish for a couple of years. I use nylon monofilament fish line like DOM does, which blends in and is easy to use. And cheap and available.
