ACHILLEA - Milfoil or Yarrow 
Showy rock and border perennials, some of which are valuable for cut 
flowers. Some have silvery and others elegantly cut foliage, which adds 
considerably to the beauty of the plants. 
Culture. All will succeed in any good, ordinary soil in sunny borders. A 
too rich soil should be avoided. Plant in autumn or early spring, 8 to 
10 inches apart. As nearly all grow freely, it is advisable to lift, divide, 
and replant every third year. Directly after the plants cease flowering, 
cut the shoots back.

moist. They are especially suitable for shady or semi-shady position, and 
are best grown in groups of three or more. Plant in autumn or very 
early spring, 6 to 8 inches apart. They display their beauty to the best 
advantage when they have become well established and formed large
