@Reine I actually did not notice the growth at the leaf nodes until the roses were pretty spent. It was then I decided to cut off the blooms and the ends and remove the leaves. At that point they had been in just water for about a week, so I don't really know if the growth was already there or maybe happened during that week.
Will be anxious to follow the progress of your cuttings. I've never attempted this so I am
all ears!
