I have over a dozen of the Midwinter Fire in my own woodland corner. Started with one plant which grew well but was in the wrong spot for deepest winter visibility so several year ago I moved it to where it gets more winter sun and I can see it from my usual perch on the sofa.
Hadn't realised that it suckers so the next spring I dug out a dozen new babies from its original spot and put some in the new woodland corner and the rest were potted up to give away. I found another half dozen the following spring. Last year loads more which I'm afraid I binned after giving two away. This year there's just the one, bang in the middle of a clump or monarda/bergamot I've been nurturing so I've just pruned that one back to the soil.
The one I have in the front suckers happily too. I find they don't take to hard pruning like the alba sibirica so now I just take out a third of the stems each year and cut the rest back to a shape. Too much sulking otherwise and thin spindly growth which is not pretty.
