Mourning Buckwheat: A Rare Nevada Native Worth Protecting

If you’re passionate about native plants and conservation gardening, mourning buckwheat (Eriogonum concinnum) might just capture your heart. This delicate annual wildflower is one of Nevada’s botanical treasures, though finding it in the wild—or in cultivation—requires some dedication.

What Makes Mourning Buckwheat Special

Mourning buckwheat is a charming little forb that belongs to the vast buckwheat family. As an annual, it completes its entire life cycle in just one growing season, sprouting from seed, blooming, setting seed, and dying back all within a year. Don’t let its ephemeral nature fool you though—this plant packs plenty of personality into its short life.

The plant produces clusters of tiny white to pale pink flowers that seem to float above silvery-green foliage. While individual flowers are small, they come together in delicate, airy displays that add a subtle charm to any garden setting.

Where Mourning Buckwheat Calls Home

This native beauty is found exclusively in Nevada, making it a true Silver State endemic. Its natural range is limited to specific areas within the state, where it grows in the wild landscapes that characterize much of Nevada’s terrain.

A Word of Caution: This Plant is Rare

Important conservation note: Mourning buckwheat has a Global Conservation Status of S2, meaning it’s considered imperiled due to extreme rarity. With typically only 6 to 20 known occurrences and few remaining individuals in the wild, this plant is especially vulnerable to extinction.

If you’re interested in growing mourning buckwheat, please only source seeds or plants from reputable native plant nurseries that ethically propagate their stock. Never collect from wild populations, as this could further threaten the species’ survival.

Growing Mourning Buckwheat in Your Garden

For Nevada gardeners lucky enough to find responsibly sourced seeds, mourning buckwheat can be a rewarding addition to native plant collections. Here’s what you need to know:

Ideal Growing Conditions

  • Sunlight: Full sun exposure
  • Soil: Well-draining, sandy or rocky soils
  • Water: Low water requirements once established
  • Climate: USDA hardiness zones 4-8

Planting and Care Tips

  • Direct seed in fall for spring germination
  • Scatter seeds on disturbed or prepared soil surface
  • Provide minimal supplemental water—this plant prefers dry conditions
  • Allow plants to self-seed for potential return the following year
  • Avoid fertilizers, which can harm native plants adapted to lean soils

Garden Design Ideas

Mourning buckwheat works beautifully in:

  • Native wildflower gardens
  • Rock gardens and xeriscapes
  • Naturalized meadow areas
  • Conservation gardens focused on rare species

Its delicate appearance makes it perfect for adding subtle texture and movement to plantings, especially when allowed to weave between other native grasses and wildflowers.

Supporting Pollinators

Like other members of the buckwheat family, mourning buckwheat provides nectar and pollen for various native pollinators, including small native bees and butterflies. By growing this plant, you’re not just adding beauty to your garden—you’re supporting the complex web of relationships that sustain Nevada’s ecosystems.

The Bottom Line

Mourning buckwheat represents both the beauty and fragility of Nevada’s native flora. While its rarity means it’s not a plant for every garden, conservation-minded gardeners who can source it responsibly will find it a meaningful addition to their native plant collections.

Remember: growing rare natives like mourning buckwheat is as much about conservation as it is about gardening. Every plant grown from ethically sourced seed helps ensure this Nevada treasure has a future, both in the wild and in our gardens.
