Against all logic.......
i have a very large miscanthus Morning Light..........prob 10 ' tall; With the flowers it will be 2' taller. Anyway, against gardening wisdom, I took a spade to it and dug it out egged on by a visitor who craved a piece of it. Massively heavy I got it out. Bear in mind I really like this grass. Divided it carefully with a saw into half a dozen large pieces and planted 3 elsewhere in the garden.
if asked on the forum should I do this I would say no....wait a few weeks....you could lose it or the flowers anyway at this time of year
however, I think it will be fine.....I even think the divisions will flower too. 
Besides I am impatient to replant the area and can see how it will look next summer with my replacements actea Black Negligee that has been growing well all summer in a large pot. Tomorrow I will move and divide a large white astrantia and set it alongside.
Saves time later too but Should really have waited a while longer..........but pleased I did it .
any other impulsive guys out there?

3 years ago, I planted 3 morning light on one side of a path, an a single specimen on the other. I'm going to remove 2 of the clump of 3 to leave one on each side. and another pair to go elsewhere.
Severely root pruned and repotted an old fern in the spring while still dormant. A few anxious weeks before it sprouted. It looks great now.
Spring is the best time to move any grass. That is when they make new roots. Doing it any other time means that it will have to survive on the roots it already had. Best of luck with it.
The great C. Lloyd when asked when do you prune such and such a shrub, said whenever I am in the mood and happen to have a pair of secateurs with me.
Plants want to live and IMO, you can do most things to most plants, most of the time.

I'm not saying it's right, or wrong. But I read that grasses prefer to be moved in Autumn when there's still a bit of warmth in the soil.
Soil being warmer in October than in April.
Is there really a plant called Black Negligee...what's it coming too,
I'm learning quite quickly that some decisions I make are those calculated risks while others are stupid ones.
Other times events don't always follow the textbook anyway. Last winter I left two lobelia cardinalis in their baskets in the pond to overwinter. I knew at the time I was supposed to lift them out and place under protection but gambled. One died but the other has survived and now looks very healthy
Sometimes it's really difficult to choose the "right" time to prune or move something. Two years ago I pruned my buddlejas at the beginning of March, usually just right for W.Yorks. However, at the end of the month we had a bitterly cold spell in which east winds blasted the garden, killing many things (including the buddleja) which started into growth early.
Verdun, since they changed Polygonum to Persicaria, the suffix has become "superba". Much less interesting...
