For Heuchera you have to worry about frost heaving. When they are in ice like this you can not replant right away. My main plants are Heuchera , Hellebore and Echinacea. None of these like wet feet and being wet to long causes crown rot. When the ground is frozen the water just sits on top and freezes. So if the plants live all the leaves on the Heuchera get messed up and need to be removed.
