I have grown this, 'the 'pearl' cultivar, in Margate, NJ, it has been wonderful, blooms mid summer to Sept., and is not invasive at all. It is a very nice filler for the perrenial bed.

Achillea ptarmica grows quite well in our cool climate in Alaska. It actually prefers poor soil. Though it's blooms are quite beautiful, resembling little roses, it can be extremely invasive if sharing a garden bed.
