Though I think the leaves of this plant are beautiful, motherwort is a non-native, invasive from central Asia, introduced to the U.S. from Europe for it's medicinal purposes. It has no real benefit to wildlife that I can find and it displaces native plants.
Motherwort is used for treating conjunctivitis in rabbits. I am not sure of the proper way to use it, but they seem quite content to mow mine down with their teeth! My information says that it is hardy in zones 3-8.

A classic example of one person's weed being another's landscape plant. This is a nice filler plant for a large landscape. I wouldn't dedicate a spot for it in a small landscape. Not real impressive in any way except being a great bee plant. Bees just love it.
Update as of 9/06/2006:
Change of heart. Yes this is a WEED. It can be very very invasive. If you plant one, I strongly suggest cutting off the spent blooms so it doesn't self-seed.
