It's a bit late now, but if there are unflowered shoots you could try. Take 4-5 inch cuttings and trim off the lower leaves, it also helps if you cut the leaves across the top to reduce the leaf area. Dip the cuttings in hormone rooting powder and push them around the edges of a small pot. Water them and put the pot in a plastic bag to keep them humid. They should root in a few weeks, then pot them on. Grow them into nice plants before putting them in the garden.
