Willamette Valley Pollinator Mix from Steele Acres Native Seed

A unique balance of annuals and perennials (native to the Willamette Valley) that will provide season long bloom for multiple years! This mix contains species that are recommended by the Xerces Society and the Natural Resources Conservation Service to attract a diverse array of native pollinators.  A small amount of native bunchgrass has been added to provide structure and habitat for ground nesting bees.

  • Size at maturity: 2-4' tall
  • Canopy layer: groundcover
  • Light requirements: full sun
  • Moisture requirements: dry to wet soil

    Coverage: 10 grams covers 100sqft. Coverage areas are based on an average of sowing rate of 60 seeds per foot.

    What will the pollinator mix look like in the first year after I plant?

    The first year, the annuals (Clarkia amoena, Collomia graniflora, Madia elegans, Gilia capitita, and Plectritis congesta), about 30% of the mix are the primary species to bloom. A few of the perennials will bloom, but not many.

    In year two, the annuals will be less dominant and the perennials will really take off. Expect lots of Yarrow, Grindelia integrifolia, Lupinus rivularis, Prunella vulgaris, Ranunculus, and Goldenrod.

    By year three, most of the annuals that haven't naturally reseeded will have dropped out, but the longer-lived perennials like Sidaceas, Potentilla gracillis, and Oregon Sunshine will be blooming strong along with the year 2 perennials.

    The mix is designed to provide long-term pollinator habitat. We have observed five year old plantings that still look good becuase the high percentage of perennials used.

    Because the annuals do offer beautiful and helpful blooms, but can be lost in older stands, we continue to evaluate ways to effectively reintroduce annual seeds into older stands with minimal disturbance to the existing plantings. (Steele Acres Native Seed)
