Echinacea

You might be able to transplant these. I have more first-hand
experience with black-eyed susan, so I'm not sure I've successfully
transplanted any of my purple coneflowers, but at least based on the
black-eyed susans, they require a lot of water in the first days after
the transplant (especially if it is hot), and can get killed off by
winter if they are transplanted late. If they make it over the
initial shock, they seem to do well. I transplanted some around May
or June and they are flowering now.

Probably too much work to worry about in the middle of a move, but
in case you were wondering...
