I was wondering how difficult it is to propogate ‘White Surprise’. I heard that it doesn’t root easily, but I cannot remember. I’m looking for very sterile roses (like Mermaid) and others to experiment this spring using cold and heat treatment to induce polyploidy. I wanted to get something sterile so that I can deduce that if a clone produce hips, it may be a polyploid.
I have never tried to root cuttings of White Surprise, but it will root wherever it touches the ground. It would be easy to propagate by layering.
Good! Now, that is what I really needed. Very easy to root, very sterile. Now, if I just only know a source to get it…
