I've had my prairie mallow for about 4 years now and it never fails to give a beautiful show. I just leave it alone and let it do what it will. Very low maintenance.

I just found out the name of this plant by seeing it at a nursery. It showed up two years ago growing out of a stone-covered area next to a cement path. Since then I have never watered it or done anything to care for it and it comes back and blooms beautifully every year - this year there is another about two feet away from the first.

A wonderful plant! Here in New Hampshire USA it grows without any care at all by me! I have never watered them or fertilized them, and they do not need weeding as they crowd out any weeds! They self seed very nicely, but I would not consider this a highly invasive plant. It blooms from June through September and often into October. It progates by self seeding and I think it may also spread at the crown as well. The seeds are VERY easily collected if you want to share this gorgeous plant with others! Hassle free and I love it! It survives very harsh extreme cold with winter winds often over 50MPH and -20F temps without any protection!
