The color on these varies. They will come in much darker red, too.
The achillea hybrids are generally from Achillea millefolium which has subspecies in Europe and the Americas. I like to think of them all as California natives since there is one native subspecies, and the hybrids seem to have all interhybridized pretty readily, so I figure that’s close enough. But apparently this one really is hybridized from the California native yarrow. Good to know.
