Blue Mountain Buckwheat: A Hidden Gem for Western Native Gardens

If you’re looking to add a touch of authentic western charm to your garden while supporting local wildlife, Blue Mountain buckwheat (Eriogonum strictum proliferum var. anserinum) might just be the perfect addition you never knew you needed. This lesser-known native perennial brings both beauty and ecological value to landscapes across the American West.

Meet the Blue Mountain Buckwheat

Blue Mountain buckwheat is a perennial forb herb that belongs to the diverse Eriogonum genus, commonly known as wild buckwheats. Don’t let the buckwheat name fool you—this plant isn’t related to the grain you might find in your pantry. Instead, it’s a hardy native that has been quietly thriving in western landscapes long before any of us thought about gardening.

This plant goes by the scientific name Eriogonum strictum proliferum var. anserinum, though it has collected quite a few aliases over the years, including former names like Eriogonum flavissimum and Eriogonum ovalifolium subspecies flavissimum. Botanists sure do love their naming conventions!

Where You’ll Find It Growing Wild

Blue Mountain buckwheat calls the western United States home, naturally occurring across five states: California, Idaho, Nevada, Oregon, and Washington. This native status means it’s perfectly adapted to western growing conditions and will play well with other regional natives in your garden.

Why Your Garden (and Local Wildlife) Will Love It

As a perennial herb, Blue Mountain buckwheat offers several compelling reasons to earn a spot in your landscape:

  • Pollinator magnet: Like most buckwheats, this species produces clusters of small flowers that attract bees, butterflies, and other beneficial insects
  • Low maintenance: Being a native, it’s naturally adapted to local conditions and requires minimal care once established
  • Water-wise choice: Perfect for xeriscapes and drought-tolerant gardens
  • Authentic native character: Adds genuine regional character to native plant gardens and naturalized landscapes

Perfect Garden Companions and Settings

Blue Mountain buckwheat shines in several garden styles:

  • Native plant gardens paired with other western species
  • Rock gardens where its natural form can be appreciated
  • Xeriscapes and water-wise landscapes
  • Wildlife-friendly gardens focused on supporting pollinators
  • Naturalized areas where you want that wild look

Growing Blue Mountain Buckwheat Successfully

The good news? This native is relatively straightforward to grow if you can meet its basic needs:

Sunlight: Provide full sun for best flowering and growth. This plant loves those bright western skies!

Soil: Well-draining soil is absolutely crucial. Like most buckwheats, this species cannot tolerate wet feet and will quickly decline in heavy, poorly draining soils.

Water: Once established, Blue Mountain buckwheat is quite drought tolerant. Water regularly during the first growing season to help establish roots, then reduce watering significantly.

Climate: Based on its natural range, this plant likely thrives in USDA hardiness zones 4-9, though local microclimates can affect its performance.

Planting and Care Tips

  • Plant in spring after the last frost date in your area
  • Amend heavy clay soils with coarse sand or gravel to improve drainage
  • Space plants according to their mature size (specific dimensions may vary)
  • Mulch lightly around plants, keeping mulch away from the base to prevent moisture retention
  • Avoid overwatering—when in doubt, err on the dry side
  • Deadhead spent flowers if you want to prevent self-seeding, or leave them for wildlife

A Note on Sourcing

Since Blue Mountain buckwheat is a specific variety, it may not be available at every nursery. Look for native plant nurseries in your region, or consider contacting local native plant societies for sourcing recommendations. Always choose plants grown from local or regional seed sources when possible for the best adaptation to your specific conditions.

The Bottom Line

Blue Mountain buckwheat offers western gardeners an opportunity to grow something truly native while supporting local ecosystems. It’s not the flashiest plant you’ll ever grow, but sometimes the most rewarding gardens are built on these kinds of quiet, dependable natives that just do their job year after year. If you’re building a water-wise native garden or simply want to try something new that belongs in your landscape, this buckwheat variety is definitely worth considering.
