This mother's day I am getting my mother a Camelot Rose Foxglove (Digitalis Purpurea). They are sold at Home Depot and take full exposure to the sun. According to the card they can survive winters to -20 to -30 degrees F.
It is a nice looking plant with a tall flowering stem with bell shaped flowers going all the way up the stem.
The Calla Lily we got her last year did not survive the winter though the one we got at the same time has.
