Growing Sedge (Carex ×deamii): A Rare Midwestern Native

If you’re looking for a native grass-like plant that’s truly unique, Carex ×deamii might catch your attention. This perennial sedge is a natural hybrid that calls the American Midwest home, though you’ll need to do some serious plant detective work to find it in the wild or in cultivation.

What Makes This Sedge Special?

Carex ×deamii belongs to the sedge family (Cyperaceae), making it a grass-like perennial that offers a different texture and growth pattern than true grasses. The × in its botanical name tells us this is a hybrid species—essentially nature’s own plant breeding experiment. This makes it particularly interesting for native plant enthusiasts who love botanical curiosities.

Where You’ll Find It Growing Wild

This native sedge has a limited natural range, found only in four Midwestern states: Illinois, Indiana, Kentucky, and Missouri. Its restricted distribution makes it a true regional specialty, perfectly adapted to the specific conditions of this area.

Should You Plant Carex ×deamii in Your Garden?

Here’s where things get interesting—and a bit challenging. While this sedge is undeniably native and likely well-suited to Midwestern gardens, finding it in the nursery trade is like searching for a needle in a haystack. As a natural hybrid with limited distribution, it’s rarely cultivated commercially.

The Reality Check

If you’re set on growing this particular sedge, you’ll face some hurdles:

  • Extremely limited availability in nurseries
  • Specific growing requirements that aren’t well-documented
  • Uncertainty about long-term garden performance

Better Native Sedge Alternatives

Don’t let the rarity of Carex ×deamii discourage you from exploring native sedges! The Midwest is home to many other beautiful, readily available sedge species that offer similar benefits:

  • Pennsylvania sedge (Carex pensylvanica) – excellent for dry shade
  • Fox sedge (Carex vulpinoidea) – thrives in wet areas
  • Plantain-leaved sedge (Carex plantaginea) – gorgeous broad leaves
  • Appalachian sedge (Carex appalachica) – great groundcover option

Growing Tips for Midwestern Sedges

While specific information about Carex ×deamii is limited, most Midwest native sedges share some common preferences:

  • Partial shade to full sun, depending on moisture levels
  • Consistent moisture during establishment
  • Well-draining soil that doesn’t stay waterlogged
  • Minimal maintenance once established

The Bottom Line

Carex ×deamii represents the fascinating diversity of our native plant communities, but it’s more of a botanical curiosity than a practical garden choice. If you’re passionate about native sedges, focus your energy on the many other wonderful species that are readily available and well-suited to garden cultivation. Your local native plant society or extension office can point you toward the best sedge options for your specific location and growing conditions.

Remember, every native plant you grow—whether common or rare—contributes to supporting local wildlife and preserving our natural heritage. Sometimes the most impactful choice is the one that’s easiest to grow successfully!
