Achillea (Yarrow) is a beautiful perennial, easily grown and suited to many climates and soil types, including clay. Yarrow has feathery foliage and long-blooming flat-topped flowers that attract butterflies. Achillea is a perennial well-suited to wildflower gardens and is drought resistant. Yarrow makes excellent cut or dried arrangements and has excellent resistance to browsing deer and rabbits. Named after Achilles himself, legend has it that yarrow was used to treat Greek soldiers' wounds. First aid aside, we just think it's a great cornerstone to any perennial garden.
