We brought a start of this plant from our rental house, so we’ve had it 25 years in this garden. It is a survivor, living on in a somewhat shady position, assaulted by bindweed, with little water or fertilizer. Every year, it blooms reliably with its showy, slightly fragrant flowers.
My future plans for this plant are to divide it and move a division out into a better position where it can be taken care of and really put on a flower display.
