I grow diablo here in 2b and it does fine; I've seen it listed as zone 2. I would think that centreglow has a similar rating being a cross between diablo and darts gold I believe. I've looked at centreglow myself and am considering it. There is another ninebark cultivar that sounds very attractive but for the life of me I can't remember its name. Anyway, I think you should be fine with your purchase. A lot of my ornamental trees are looking worse for wear this year; it was a difficult fall and winter!

I have Coppertina and Centreglow. The Coppertina has come through three winters quite well, though there was a lot of tip kill this year. This was the Centreglow's first winter and it came through quite well considering the tough winter we had. It's a good choice, Marie!

Oh, Thank you for those encouraging words.
Now to get my DH to cooperate. I will need his help to get that shrub out of there. There's no way I can attempt it myself.

I'm hoping to get mine out this summer too, and i think it's going to be a big job. It's not very big, but i imagine the roots are way out there!

You're wise to get your DH to help remove that shrub. Don't try to do it when he's not home.

This morning I was planting my new Blue Fox Willow near where a tree had been removed and it's stump ground.

I, of course, came upon some roots as I was digging my hole. Holy Cow! At first I thought the previous owner had buried a piece of 2x4 or something. One of the roots was so big I thought I was going to break the shovel handle trying to pry it out! Two other ones needed to be cut and pulled out.

When will I ever learn......

I'm starting to realize my limitations.......
