The nights are getting longer and colder up here in the north. Days are still nice and warm but you can feel the autumn coming.
Few years ago I had some extra yarrow seeds and just threw them around. The end result is that I now have Cerise Queens (Achillea millefolium ‘Cerise Queen’) growing here and there.
We have the white form of yarrow as a native plant but no other colors. Cerise Queens are easy to spot since they just stand out.
