Don't ever think of moving it.
If you do, make certain it's way dormant. This stuff is gorgeous, and deadheading keeps it blooming. However, it does NOT like to move.

I had some in a pot, buried over winter. Earlier this year, in the beginning of the heat, I pulled up the pot and planted it. It's been playing dead (I hope) since a week after. It is extremely picky -- at least for me!

But the stuff is a good pink, isn't it?
