Achillea found in a park garden in Charleston. There were a few varieties of this smaller flower. I usually concentrate on single blossoms. It’s easier.
The plant was identified by Liz of Exploring Color in New Zealand. Liz, and her husband Nigel, are the experts I so badly need. Nigel is a Landscape Architect from GrowPlan . Liz manages Nigel so I know we are on the right track here.
