I forgot to post about my Blue Moon wisteria! This is the first year I have ever had a flower on my wisteria vine (bush? tree?).
It's been growing for 4 years. It is VERY hardy. I don't protect it at all in the winter and it's in a fairly exposed area. So Blue Moon wisteria really is hardy in Minnesota zone 4!
This is what it looked like to start out.
I wasn't sure what it was going to look like when it bloomed, because I've never seen a wisteria bloom.
It was more purple than blue, but it shows up very blue in pictures. I bought this vine at Menard's, of all places, for about $25. I go back every year and ask them if they have any more. Every year they look at me like I'm crazy - "Wisteria? What's that?"
