    This geranium is a true perennial and has been established in my (zone 5 ) garden for 10+ years. It does not need to be divided. I have divided mine once to place a plant in a new location. I have it growing both in full sun and in afternoon shade. the shaded plant is a bit taller (by 20%), but there is no noticeable bloom difference. In wet years it gets a bit floppy. It receives no additional water in my garden.
