A great performer for late summer, looking fresh when everything else looks past it. Its pale mauvey-blue daisy-shaped flowers fit effortlessly in traditional mixed borders as well as in big sways in a more prairie approach. Although able to cope with dry spells, it likes some moisture. Can become invasive in the right conditions.
