'Moonshine' is the only Achillea that I grow - I think. After dispatching with other varieties that were variously too aggressive, or which faded to dishwater colour after a few days in sun, 'Moonshine' was excellent in Zone 5. In Pacific Zone 9 it was a bounding monster. We shall see what transpires in Zone 7.
This plant has a very long bloom time and works well as a cut flower.
