What Is Yarrow (Achillea Millefolium)?

Field of white and blue Achillea (Yarrow) flowers.

Yarrow, scientifically known as Achillea millefolium, is a hardy perennial native to temperate regions of the Northern Hemisphere. Its feathery, fern-like leaves and flat-topped clusters of tiny flowers (in shades of white, yellow, pink, or red) make it a standout in any garden. Historically, yarrow was used by Achilles to treat soldiers’ wounds—hence its genus name—and it’s still prized today for its medicinal properties.


Why Grow Yarrow in Your Garden?

Here’s why yarrow deserves a spot in your garden:

  • Drought-resistant: Yarrow thrives in poor soil and needs minimal watering once established.
  • Pollinator magnet: Butterflies, bees, and beneficial insects adore its nectar-rich blooms.
  • Medicinal uses: Its leaves and flowers can be made into teas or salves for minor cuts.
  • Versatile beauty: From ground covers to cut flowers, yarrow suits many garden styles.

A few summers ago, during a brutal drought here in Colorado, my yarrow patch was the only area that stayed vibrant without extra watering. Talk about a low-maintenance hero!


How to Grow Yarrow from Seedlings or Seeds

Starting from Seedlings

If you’re new to gardening, begin with Achillea millefolium seedlings from a nursery. Plant them in well-draining soil with full sun (6+ hours daily). Space them 1–2 feet apart—they’ll spread!

Growing from Seeds

Yarrow seeds need light to germinate. Scatter them on soil in early spring, press gently, and keep moist. In my experience, seedlings emerge in 14–21 days. Pro tip: Soak seeds overnight to speed up germination.


Popular Yarrow Plant Varieties to Try

When it comes to types of yarrow, there’s more than the classic white species. Here are my favorites:

  1. ‘Moonshine’: Lemon-yellow blooms and silvery foliage (drought-tolerant!).
  2. ‘Paprika’: Fiery red flowers that fade to pink—stunning in bouquets.
  3. ‘Strawberry Seduction’: Vibrant pink clusters with a compact growth habit.

Caring for Your Yarrow Plants

  • Watering: Only during extreme dry spells. Overwatering causes root rot.
  • Pruning: Deadhead spent blooms to encourage reblooming. Cut back to 6” in fall.
  • Dividing: Every 3–4 years in spring to prevent overcrowding.

I once neglected my yarrow for two years (oops!), and it still came back stronger. That’s resilience!

  • Decor: Pair dried yarrow with lavender for rustic arrangements.
  • Companion planting: Yarrow boosts nearby herbs’ essential oils. Try it near rosemary or thyme.
