"The Yarrow æMoonshineÆ, Achillea 'Moonshine'Æ, is an upright canary-yellow flower that blooms from June through September. With evergreen foliage in mild winter regions, this non-spreading Achillea is a definite winner. æMoonshineÆ Yarrow is unlike the common Yarrow, being shorter in height and less invasive. The flower heads are 4ö wide, with a spread of 18-24ö and a height of 24ö. Remove faded flowers to encourage more growth and divide every 3-4 years. For an attraction to butterflies, deer and rabbit resistant, one canÆt go wrong with this plant."
