Although some of the flowers are pretty and all are handsome, I have declared this a public menace in our garden. It simply seeds too freely, and the rhizomes stomp all over the neighbors - and what they don't stomp, they shade. We're in Zone 4, with sandy, slightly acidic soil, and that seems to be just what mourning widow wants. Since I don't want to have to mourn for all my other lost treasures, out it goes. It may be more polite where you live, but please think before planting this.

This is one of my favorite hardy geranium. It has a neat clump form in the spring, and the leaves are zoned with a dark pattern. As the season progresses, it takes a much larger spot in the garden, and grows to over 3 feet in height. There are profuse purple blooms that cover the plant. This is an avid self-seeder. In our South Central Alaskan climate, I mulch it for the winter.
Mourning Widow geranium is an attractive plant coming from mountainous areas of Europe. It is very hardy here and likes evenly moist, lightly acidic soil; it seems to do well in part shade where I have it planted. I grow the white, as well as a dark maroon purple color. Blooms are graceful and somewhat pendulous on thin stems about 12-16" in height. They seem to add a 'woodland' atmosphere to the garden. Both self seed.
Clump forming hardy Geranium from moutainous regions of Europe and Western Russia. Has lobed, soft green, slightly hairy leaves sometimes with a purple mark. Bears deep maroon, almost black, violet blue or white, 5 petalled, slightly reflexed flowers up to 1 inch across.
Flowers end April - July with the occasional flower appearing throughout the season.
Likes damp soils in partial shade but not soil that lies wet and will tolerate sun.
