Preferences:

European and Western Asian perennial, although white flowering yarrow in Canada is native to North America and can be found all the way into the Yukon. Yarrow prefers full sun, well drained soil, very drought tolerant. Poor soil is better for growth than rich soil as it will keep the plant more in check.

Cultural Practices:

Propagation: Sow in light at 21 degrees for 10 days. Division is preferred and is best done in the fall or in spring after being cut down, although, yarrow can be moved anytime provided it is cut back and well watered in.

Culture - The flowers come out a rich colour and then fade into different colours. They should be deadheaded but this is difficult because the flowers are all in different stages of maturity. Yarrow flops over as it ages. In shade conditions it is susceptible to powdery mildew. It must be cut back in fall or it will seed profusely.

Landscape Value:

Common Cultivars - 'Cerise Queen', 'Paprika', 'Summer Pastels'

Other Species - Achillea ptarmica 'The Pearl' - Sneezewort has white flowers that look like giant sized baby's breath. Dries nicely, shouldn't get rich soil though or it will get too gangly.

Achillea tomentosa - A very small mustard coloured yarrow usually found in rockeries

Achillea filipendulina 'Cloth of Gold' - Big bold yellow disks of flowers that are excellent in flower arrangements.

Combinations:

Yarrow, Bee balm, Echinacea, Sneezewort, and Artemisia absinthium, Ribbon grass or Karl Forester Grass. When used together create a prairie styled garden (a form of cottage style that has a little more wild look).
