Son’s Buckwheat: A Rare Utah Native Worth Protecting

Meet Son’s buckwheat (Eriogonum natum), one of Utah’s lesser-known botanical treasures. This perennial wildflower might not be a household name, but it represents something special in the world of native plants – a rare species that calls only the Beehive State home.

What Makes Son’s Buckwheat Special?

Son’s buckwheat belongs to the diverse buckwheat family, known scientifically as Eriogonum. While its more famous cousins like sulfur buckwheat grab attention with showy displays, this particular species flies under the radar. It’s what botanists call a forb – essentially a soft-stemmed perennial that dies back each winter but returns from its roots each spring.

What makes this plant truly remarkable isn’t its size or flashiness, but its exclusivity. Son’s buckwheat is found nowhere else on Earth except Utah, making it what we call an endemic species.

Where Does It Call Home?

This rare wildflower has chosen Utah as its one and only home base. Within the state’s diverse landscapes – from red rock canyons to high desert plateaus – Son’s buckwheat has carved out its unique niche.

A Plant That Needs Our Protection

Here’s where things get serious: Son’s buckwheat carries a Global Conservation Status of S2Q, which puts it in the rare category with some uncertainty about its exact classification. This means that while it’s not on the brink of extinction, it’s certainly not common, and we need to be thoughtful about how we interact with it.

For gardeners, this rarity status comes with both opportunity and responsibility. While growing native plants is generally encouraged, rare species require special consideration.

Should You Grow Son’s Buckwheat?

The short answer is: maybe, but with important caveats. If you’re a Utah gardener passionate about supporting truly local flora, Son’s buckwheat could be a meaningful addition to your landscape. However, there are crucial guidelines to follow:

  • Source responsibly: Never collect seeds or plants from wild populations. Only purchase from reputable nurseries that propagate from legally obtained, ethically sourced material
  • Consider alternatives: Utah has many other beautiful, less rare buckwheat species that can provide similar ecological benefits without conservation concerns
  • Think long-term: If you do grow it, consider yourself a steward helping preserve genetic diversity

Growing Conditions and Care

While specific growing information for Son’s buckwheat is limited due to its rarity, we can draw from general buckwheat family characteristics:

  • Soil: Likely prefers well-draining, rocky or sandy soils typical of Utah’s terrain
  • Water: Probably drought-tolerant once established, like most buckwheats
  • Sun: Full sun exposure is typical for the family
  • Climate: Adapted to Utah’s climate extremes and elevation changes

Given its perennial nature, Son’s buckwheat should return each growing season, though it may remain dormant during harsh winter conditions.

The Bigger Picture

Sometimes the most important plants aren’t the showiest ones. Son’s buckwheat represents Utah’s unique botanical heritage – a reminder that every state has special species found nowhere else. Whether you choose to grow it or not, knowing about plants like this helps us appreciate the incredible diversity right in our own backyards.

For most gardeners, supporting Son’s buckwheat might mean advocating for habitat protection, supporting botanical research, or simply choosing other native Utah plants that can provide similar benefits without conservation concerns. Sometimes the best way to love a rare plant is to let it thrive where it belongs – in the wild landscapes it has called home for thousands of years.

Native Alternatives to Consider

If you’re drawn to the idea of buckwheats but want to avoid rare species concerns, Utah offers several other beautiful Eriogonum species that are more common and readily available through native plant nurseries. These can give you the drought tolerance, wildlife benefits, and native plant satisfaction without the conservation complications.

Remember, every native plant we grow – rare or common – is a small act of environmental stewardship. Son’s buckwheat might be exclusive to Utah, but the principles it represents – choosing local, supporting biodiversity, and gardening with conservation in mind – are values we can all embrace, no matter where we call home.
