I've owned Kateryna for years. It consistently produces a showstopping spring bloom and it continuously reblooms all season long. What I like best about it is that it has so many blooms, the foliage almost doesn't show at all. It's one of my favorite roses. It does not do well in high temps (>90) or intense summer sun, so I planted a tree that shades it in the late afternoon.
I'm in zone 9b. I received this rose on October 18, 2021. It now is December 12 and Kateryna has multiple blooms. Her flowers may be small but they are bright and beautiful.
It is still so little. The growth is probably 3-5 inches in one season. I am excited about it and love the way it smells when it blooms. I think it's going to be a beauty.
I'm in zone 6 in Illinois near St. Louis and this rose does wonderfully here. It loves the heat and just keeps sending more and more flowers. The whole bush literally covered all summer long. Can barely see the flolage which is a shame since it has very pretty leaves. One of my favorites.
