I saw a rose called 'Summer Waltz' at the arboretum yesterday. It was a beautiful pink, and fragrant.The label said it was a 2012 U. of Minn. introduction, 'UMNRosa66', part of a series called 'Suddenly Summer'. I tried to find it online but no one is selling it. I found this reference: https://patch.com/minnesota/lakeminnetonka/introducing-the-summer-waltz-a-new-rose-unveiled-by-arboretum. I've attached my photo of it below. I'd love to buy this rose if it's available anywhere! It looked so nice and healthy, and was a good height too.
