A few days ago this plant was a mass of buds in the rain. Now the rain has stopped and the buds are opening. Individually the flowers are not really all that amazing, five small, simple, pink petals around a bunch of yellow stamens. In mass they are quite impressive. The entire plant is turning from green to pink and will get pinker before it is done. I picked out one picture to post here and then second guessed myself. I found that I couldn’t decide which one I liked better so I’m posting them both.
Of course, like most rose species, this one only blooms once and then it’s done for the year. It also has very little fragrance. My dream is to cross this with roses that repeat and which have fragrance to get some of the multiflora vigor and disease resistance into a new group of hybrids. Whether that’s ever going to happen is anyone’s guess. Another project, even before crossing it with anything else, is an attempt to double the chromosomes. R. multiflora is, like many rose species, diploid (it has 14 chromosomes). Many hybrid garden roses, including most hybrid teas and floribundas and a lot of the roses I’d cross like to make crosses with, are tetraploid (28 chromosomes). For breeding purposes, a cross between a diploid and a tetraploid is problematic because it produces triploid offspring, which are, with notable exceptions, sterile.
