An Autumn Chop ?

Back in early September when I was clearing and replanting the woodland part of the garden, I got ruthless with some of the leggy Japanese Anemones and cut them right back. Most had finished flowering anyway and even these toughies were struggling in the low light conditions before I pruned back the lower branches of the trees and shrubs. All the new planting has settled in nicely and to my great surprise some of the anemones have sent up new leaves and flower stems that are about a third of their usual height.  Could this be a technique for getting later and lower flowers?  I’m going to try it again next year and see.
