Hi Katie,
This shrub is a great one to have, hard as nails, lots of flowers nearly all year, I have had them as late as December before,evergreen, and can be really hard pruned. The one I have now is a cutting of my very first one I bought 15 years ago, which I left behind 2 gardens ago. I took many cuttings off this last year, like you, and now have about 25 strong, healthy little plants which I intend to plant as a hedge and they soon ramp on when they get put in the ground. There are a few different colour pinks,and a white, which I am going to keep and eye out for to add to the one I have got already. A 'good-doer', as the professional gardeners would say,and as you have seen great for our bees....
