Hitchcock’s Blue-Eyed Grass: A Rare Oregon Native Worth Protecting

Meet Hitchcock’s blue-eyed grass (Sisyrinchium hitchcockii), one of Oregon’s most precious botanical treasures. This delicate perennial is so rare that it’s considered imperiled, with only a handful of known populations scattered across the state. If you’re a native plant enthusiast with a passion for conservation, this little wildflower might just capture your heart—though growing it comes with some important considerations.

What Makes This Plant Special?

Hitchcock’s blue-eyed grass belongs to the iris family, despite its grassy name. Like other members of the Sisyrinchium genus, it’s actually a forb—a non-woody flowering plant that dies back to ground level each winter and returns with fresh growth in spring. This perennial beauty represents millions of years of evolution, perfectly adapted to Oregon’s unique ecosystems.

A True Oregon Native

This plant is exclusively native to Oregon, making it a true regional specialty. While many blue-eyed grass species can be found across North America, Hitchcock’s blue-eyed grass has chosen Oregon as its one and only home. Its presence in your garden would represent a genuine piece of Oregon’s natural heritage.

The Rarity Factor: Why This Matters

Here’s where things get serious: Hitchcock’s blue-eyed grass carries a Global Conservation Status of S2, meaning it’s imperiled. With typically only 6 to 20 known occurrences and possibly fewer than 3,000 individual plants in existence, this species is walking a tightrope toward extinction. Every plant matters.

If you’re considering growing this species, please only source it from reputable native plant nurseries that propagate from ethically collected seeds or legally obtained plant material. Never collect from wild populations.

Garden Potential and Growing Conditions

While specific cultivation information for this rare species is limited, we can make educated guesses based on its wetland status and family characteristics:

  • Moisture needs: As a facultative wetland plant, it can tolerate both wet and moderately dry conditions
  • Soil preferences: Likely prefers well-draining soils that don’t stay waterlogged
  • Sun requirements: Most Sisyrinchium species prefer full sun to partial shade
  • Climate: Adapted to Oregon’s climate zones

Why Grow Hitchcock’s Blue-Eyed Grass?

Growing this rare native offers several compelling benefits:

  • Conservation impact: You’ll be helping preserve a species on the brink
  • Authentic native landscaping: True regional natives create the most authentic habitat
  • Educational value: A conversation starter about plant conservation
  • Ecosystem support: Native plants support local wildlife in ways non-natives simply can’t match

The Responsible Approach

Before adding this rare beauty to your garden, consider these important points:

  • Work only with nurseries that can document legal, sustainable sourcing
  • Consider it a stewardship responsibility rather than just a garden plant
  • Keep detailed records and consider participating in citizen science projects
  • If propagation is successful, share seeds or plants with other conservation-minded gardeners

Alternative Options

If Hitchcock’s blue-eyed grass proves difficult to source responsibly, consider other Oregon native Sisyrinchium species that might be more readily available, such as western blue-eyed grass (Sisyrinchium bellum) or Idaho blue-eyed grass (Sisyrinchium idahoense). These relatives offer similar garden benefits without the conservation concerns.

The Bottom Line

Hitchcock’s blue-eyed grass represents both an opportunity and a responsibility. For the dedicated native plant gardener willing to source it ethically and grow it thoughtfully, this rare Oregon endemic offers a chance to participate directly in plant conservation. Just remember: with great rarity comes great responsibility. Every seed, every plant, and every successful garden population could play a role in ensuring this species has a future in Oregon’s landscapes.

Sometimes the smallest plants carry the biggest conservation stories—and Hitchcock’s blue-eyed grass certainly fits that description.
