Yarrow or Milfoil,

Several people are familiar with the wild white yarrow with its flat clusters of flowers, but most garden specimens are yellow, and some are pink or red. All have ferny leaves, sometimes with a grayish cast. They are easy to grow and bloom for a long time in summer. Most hybrids are varieties of Achillea millefolium or A. filipendulina, “Moonshine” is a pale yellow with gray leaves and grows up to two feet. “Coronation Gold” is bright yellow with greener leaves, and grows to three feet. “Fire King” is two feet and pinkish red. “Gold Plate” is among the tallest. A.tomentosa is a very pleasing low variety that forms a mat of whitish leaves and has flowers less than a foot tall. It is nice in the rock garden or at the front of the border. Yarrows are sun loving and drought resistant. Some are rather spread and need to be divided frequently. All in fact benefit by division every few years in fall or early spring.
