What is Western Yarrow?

Western Yarrow (Achillea millefolium) is a hardy perennial wildflower prized for its feathery foliage and clusters of creamy white blooms. A versatile native plant, yarrow thrives in a variety of soils and is drought-tolerant once established. It blooms from late spring through fall, attracting butterflies, bees, and other beneficial pollinators to the garden. Gardeners love yarrow for its low maintenance and resilience,and it can even handle coastal conditions and moderate shade. Use Western Yarrow in waterwise landscapes, wildflower meadows, or as a fragrant, long-blooming cut flower. This tough plant will spread slowly over time via rhizomes, creating a natural carpet of greenery topped with flat-topped flower clusters that add classic charm.

Planting Guide

When to Start & Weed Control

Start prepping your planting area in fall, so that you are ready to seed between late September and early February, when temperatures cool and rain is on the horizon.
Weed your growing area BEFORE planting any native seeds. We recommend not only pulling visible weeds but also “flushing out” the weed seeds that are waiting in the soil. Irrigate the area and wait for weed seeds to germinate, then remove them using your method of choice. Irrigate again, wait, and perform another round of weed control. Repeat 2-3 times.

Soil Prep

Ensure your soil is as bare as possible for the maximum amount of seed-to-soil contact. If the entire area can’t be completely cleared, rake out as much dead plant material from the area as you can to create bare patches of soil for the seed to make contact with. For best results, the soil should be easily crumbled and not heavily compacted.

Seeding

It is best to seed onto slightly damp soil. If necessary, water the top 1/4 inch of soil before seeding. Scatter seed directly on the soil surface and rake gently or lightly press the seed into the soil. Do not bury the seed deeper than 1/4 inch into the soil.

Water

After planting, keep the top 1/4 inch of soil consistently moist until the seeds have germinated and the first true leaves have emerged. A good rule is to water lightly every day intul the seedlings are an inch high, then you can reduce watering to every 3 days. Skip days when it rains. Within 6 weeks after germinating, your plants should need only occasional watering. Don’t over-water your plants, especially in summer.

Questions & Answers

Is yarrow invasive?

Yarrow can spread by rhizomes and self-seeding but is easily controlled by dividing clumps or mowing.

Will yarrow grow in shade?

Yarrow prefers sun but tolerates partial shade; too much shade reduces flowering, emphasizing the green-silver foliage.

How often should I water yarrow?

Very sparingly once established—rely on rainfall.

Do you cut back yarrow after flowering?

Deadheading prolongs bloom; cut stems in late fall if desired.

Is yarrow deer resistant?

Yes—aromatic foliage deters deer and rabbits.

Can yarrow be used as a lawn alternative?

Though uncommon, some gardeners use yarrow as a kind of lawn substitute for low-traffic areas. However, it requires more frequent irrigation to achieve a ‘green carpet’ look.
