This is a charming little species, with its one inch cool pink, sweetly scented blooms that start in mid-June and continue on and off through August. It tends to prefer damp locations, and shade, whenever possible. I have a couple of hybrids from last year that are now making sturdy shrubs in the test garden, but none have bloomed yet.
The plants of R. pisocarpa here on the farm are mostly thornless, especially towards the outer canopy of the shrub, and it is always graceful with its upright habit that tends to arch horizontally towards the top of the plant. I'm hoping to capture some of its graceful architecture in its offspring, as well as its cluster flowering habit and perfume.
All of the literature I have encountered lists this as a diploid, so it might be very useful for anyone wanting to work on a Winter hardy line of diploids. Pollen, as always, available upon request.
