Credo Yarrow (Achillea 'Credo')
ah-KILL-lee-ah 'Credo'

Deciduous Perennial Upright in the Asteraceae Family
A sturdy hybrid yarrow (Achillea millefolium × A. filipendulina) with flat clusters of sulfur-yellow flowers fading to cream through summer. Long-blooming, drought-tolerant, and beloved by pollinators — an RHS Award of Garden Merit winner.

Achillea 'Credo' is a hybrid yarrow bred in 1990 by German plantsman Ernst Pagels, one of the first crosses between common yarrow (Achillea millefolium) and fernleaf yarrow (Achillea filipendulina). It combines the sturdier, more upright stems of its filipendulina parent with softer color from millefolium, producing broad, flat-topped clusters of sulfur-yellow flowers that gradually fade to cream as summer heats up.

Finely cut, gray-green foliage forms a low mound beneath tall, wiry flower stems that hold up well without staking. The flowers are long-lasting both in the garden and as cut or dried flowers, and the plant earned the Royal Horticultural Society's Award of Garden Merit in 1999.

Pros

  • Long summer bloom of flat, sulfur-yellow flower clusters that age gracefully to cream
  • Sturdy, self-supporting stems that rarely need staking
  • Drought-tolerant once established and deer- and rabbit-resistant
  • Excellent as a cut or dried flower, and a magnet for pollinators

Cons

  • Can be short-lived, especially in heavy or poorly-drained soil
  • Susceptible to powdery mildew, rust, and stem rot in humid conditions or overly wet soil
  • Flowers fade to a paler cream in hot weather, losing some of their early-season color
Highlights A sturdy hybrid between common yarrow and fernleaf yarrow, valued for its long season of flat, sulfur-yellow blooms that fade to cream, its drought tolerance, and its appeal to pollinators — an RHS Award of Garden Merit winner.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
