My Rose du Rescht has produced two tiny identical plants. I installed it in 2003, and I am thrilled by it. I cut it back hard a couple of years back to rejuvenate it, and that may have been a factor. One of them bloomed this year while less than six inches tall.
Yes, Cali Sue, there are three separate new young plants coming up around the rose bush that appear to be baby versions of the same thing. They range from about 2 1/2 to 3 1/2 feet away from the adult bush.
I will take pictures when the hail we got last night melts off. :-( Assuming the babies survived.
It is a Rosa 'Radcon.' I planted it in 2008. Earlier this spring I cut it back hard and this is the first year that I have done that and also the first year that there have been any "babies."
Since the rose in question, is Knock Out (or a sport of it) it seems unlikely it would make suckers...could you have left clippings of the rose on the ground, and it rooted? That happens...does the rose produce hips that have seeds in them?
If they are 2-3 ft away and haven't bloomed yet, they may not be the same rose. Could it be that there may be some roots remaining from a previous plant in the ground and they are just now coming to the surface?
