I bought a Hosta 'Blue Angel' perhaps six years ago and it has been quite happy in a bright corner between the house and front porch. Last Autumn I noticed that there were two stems (or perhaps trunks as this thing is huge) and figured that I probably should divide it but I let time go by and forgot about it. A week ago I was cleaning the dead leaves from that corner and noted that there are now _five_ of them coming up. One or two is really enough to fill that entire corner.
Is it too late now to think about dividing it? Will I simply cause troubles for the original plant(s) by dividing so late?
