In my opinion, you can prune them all in February, treat them as Group 3, and they will then flower later on new wood, with smaller flowers, OR, don't prune them, treat them as Group 2, and they will all flower on old wood with larger flowers. I am saying that these Groups 1,2, 3 ( or A,B,C ) are man made, the plants are pruned to suit the gardener, not the plant. Just my opinion, shoot me down !!
