Zuzu, it is interesting what you said about dependability of own root roses. Up in Minnesota I have been told to try to purchase own root if possible because of the cold temps. We bury bud unions several inches down so even the grafted roses are fairly safe., but they may sucker easily. This year the coldest it has been is -18F so not too bad. But it does get -25F or colder and then, depending on rootstock, the grafted may die off or sucker from the rootstock. I'm just getting back into growing roses (or flowers in general). Maybe the rose forum would have more on the advantages of certain rootstocks. Our season is short so need plants that get to it - vigorous and continuous, with fragrance if possible.
SusaninSB, how could you order too many roses?
Being zone 4, I am jealous of all the wonderful roses everyone is ordering.
