Woolly Yarrow

Availability: Out of stock

Need a touchably soft yellow groundcover? The Wooly Yarrow (Achillea tomentosa) is the classic dwarf version of a formidable perennial! It forms a tight, low-growing mat of fuzzy olive-green foliage. It has a texture that begs to be touched. Don't be surprised to find people petting these plants!

This evergreen is then topped by big, flat clusters of canary-yellow flowers through the late spring and early summer. They are very showy and are quite striking against the subdued colored fuzzy leaves. Pollinators show up in droves for these native flowers, sipping the nectar or collecting pollen, sometimes until frost in some areas!

Wooly Yarrow is wonderfully cold hardy throughout USDA planting zones 3 to 8, and only grows 8-12 inches in height when in bloom! The down-covered leaves can spread to form colonies 18-24 inches wide or wider over time! The foliage can even be semi-evergreen to fully evergreen in warmer climates and mild winters.

Planting and Application:

When you have a hot, dry, sunny location in your garden (think real rock garden situation - tough soil, fast drainage, radiating heat) you have a handful of plants that will really live and thrive there. Yarrows are some of the best performers in these challenging garden situations. At the top of that list is Wooly Yarrow!

Its spreading nature means Wooly Yarrow becomes a low-maintenance mass-planting candidate! Yarrow stands up to some harsh conditions once you get them established in their first year. Plant your along sunny pathways, sidewalks, and along the street for bright yellow color all summer long!

Use Wooly Yarrow in the front of the border where it makes a pretty and unique edging plant! It works especially well with other Mediterranean-type plants - Penstemons, Lavenders, and Sages for instance. Or mix with other Yarrow plants! Your Pollinators will be happy with any mixture of these perennial plants you provide for them!

It looks fantastic cascading out of big classic Mediterranean urns. It also has a very home-spun look and works extremely well in Cottage gardens and Rock Gardens - where it has been a staple for decades! The fuzzy foliage is the perfect counterpoint to simple modern gardens, Sensory gardens, and mixed-perennial beds or planters!

#ProPlantTips for Care:

Perennial Yarrow needs full sun to bloom and grow the best and is tolerant to hot and humid summers. It can tolerate poor soil conditions but does best in lean, dry-to-average moisture settings in very well-drained soil. Despising soggy soil and wet roots, avoid heavy clays and moist, rich, fertile soils.

Water consistently through their first year, but once established, Yarrow won't need much except during extended drought. Top the root system with a 3-4 inch deep layer of arborist mulch.

Deadhead spent flowers to encourage a rebloom. It is recommended you divide these perennials every 3-4 years in the spring and prune your mounds back each year in early spring before you see new growth. Attractive to butterflies, but pest, disease, deer and rabbit resistant, Yarrow are rugged little garden gems with a carefree attitude!

  • Performs Beautifully in Heat & Full Sun
  • Drought Tolerant & Tolerates Dry Rocky Soil
  • Needs Well-Drained Sites
  • Moderate to Low Moisture Needs Once Established
  • Prune Early Spring
  • Rabbits & Deer Resist This Cultivar

This is a great perennial that isn't used enough in today's landscapes! Reduce water usage, feed pollinators, and reduce your workload with the hardy little native Wooly Yarrow! Try some in your garden today from NatureHills.com!
