The Vibrant Peony Gardens of the Pacific Northwest: A Comprehensive Planting Guide

The Vibrant Peony Gardens of the Pacific Northwest

Imagine, if you will, a cool spring morning in the Pacific Northwest, stepping outside to the sight of your garden, ablaze with the vivid colors of peonies. The hues of your peonies—reds, pinks, corals—seem to glow more intensely than anywhere else in the world.

Welcome to the joy of peony gardening in the Pacific Northwest!

The Perfect Canvas - Soil and Climate

The Pacific Northwest provides one of the best soils for peony growth. It's a rich tapestry of macro and micro-nutrients that peonies love. It's no wonder why commercial peony growers have chosen Oregon and Washington for their operations.

The climate here is reminiscent of a British garden, with the cool, wet springs acting as the perfect stage for peonies to showcase their full potential. The cool nights during spring in the PNW mean that blooms last longer on the plant, and the colors they produce are deeper and more vibrant.

Planting Guide

When planting peonies in the Pacific Northwest, you're essentially tucking them in for a long, prosperous life. Here's how to do it:

  1. Find the Right Spot: Peonies love the sun. They need at least 8 hours of sunlight daily. Try to plant your peonies away from the moist areas near your home where they might not get enough sun.

  2. Plant at the Right Depth: For herbaceous peonies, plant so that the eyes (the small red buds on the roots of a bare root peony) are about 1-2 inches below the surface of the soil. Planting too deep can hinder blooming.

  3. Water and Care: Peonies are low-maintenance plants once established. However, during the first year, make sure to water regularly, especially during dry spells.

State-by-State Soil Guide

Each state in the Pacific Northwest has unique soil characteristics.

  • Oregon: Western Oregon has a wet, marine climate with fertile soil, perfect for peony growth. Eastern Oregon's high desert climate requires careful watering and good soil preparation.
  • Washington: From the moist, forested areas of western Washington to the drier eastern side, peonies can thrive with the right care and attention.
  • Northern California: Northern California offers various microclimates. In general, peonies do well in areas that experience chillier winters and less scorching summers.
  • Idaho: Idaho's diverse climate ranges from zones 4 to 7. Peonies can grow well here, particularly in well-draining soil and sunny locations.


Growing peonies in the Pacific Northwest is an opportunity to paint with nature's most vibrant colors. Embrace this chance and transform your garden into a canvas of breathtaking peonies that will light up those cool spring mornings. Remember, with the right care and attention, you can cultivate a peony garden that rivals the brilliance of any British garden. Enjoy the journey!
