L56-1 is a Jim Sproul mini breeder, 'L56-1' Rose I believe is a fertile triploid as it breeds like a triploid. It’s the first successful mate with R. Minutifolia!
The top foliage is L56-1. Middle is, of course, Minutifolia. Bottom is L56Min2 'L56min2' Rose , the hybrid I most often use. That on the left is one of the L56Min2 selfs. The right is also a self but of the one which suckers, none of the others in this group does.
