Achillea millefolium, common name Yarrow, grows best in dry to medium moisture, well-drained soils in full sun. Protect the plant from strong winds as the stems tend to flop especially in hot, humid climates. The ‘Moonshine’ hybrid cultivar is a fuss-free, heat-loving bloomer with large clusters of canary yellow flowers on narrow stems, lofted above ferny, grey-green foliage clumps. It is also more compact than traditional Yarrow, growing only to 2″ in height at maturity. The fern-like, aromatic foliage and long lasting yellow flowers, 2-4″ across, last throughout the summer months. Herbalists value yarrow for its medicinal properties. Yarrow can be a bit aggressive for use in borders so it is best allowed to naturalize in out of the way sites or in mass plantings for a bold band of color throughout the summer. This Yarrow, like all Yarrows, is highly attractive to butterflies; plant in mass with Coneflowers and Coreopsis.
