Two years ago my daughter was given a red rose on valentines day. When the flower head had died It looked as if the stem and leaf were still healthy, so I dead headed it and trimmed the stem then just pushed it into a pot in the garden. You can imagine my amazement when it started to throw out some shoots and then produced a beautiful red flower and then two flowers last year and looks to be doing even better this year. This year my wife was given eight yellow roses for mothers day, so I decided to do the same. out the eight six are growing. My question is :- I was always told that roses should be grafted onto a wild rose stock and wont grow any other way. I did notice that the roses Ive planted were of the thorn less variety would this make a difference?. Ive never heard of this happening before (I,m 53) Have you?
