Hello ~ I dug up a rose vine growing in my mothers yard that she didn't want. She said it never bloomed and only put out one long stem. So, I took it from MO to Iowa last fall, I trimmed it back and it threw out 3 more stems. It survived the winter but I had to trim it down some. Well... it's growing great but it still won't bloom. How many years will it take to bloom? I still don't know what it is.
