Britton’s Spikerush: A Rare Native Gem for Wetland Gardens
Meet Britton’s spikerush (Eleocharis brittonii), a delicate annual sedge that’s quietly making waves in the native plant world. This unassuming little grass-like plant might not win any flashy flower contests, but it’s got something far more valuable: it’s a true native treasure that’s becoming increasingly rare in the wild.
What Makes Britton’s Spikerush Special?
Don’t let its humble appearance fool you. Britton’s spikerush is a member of the sedge family (Cyperaceae), giving it that characteristic grass-like look that blends beautifully into naturalized landscapes. As an annual plant, it completes its entire life cycle in one growing season, making it a fascinating addition for gardeners who enjoy watching plants change throughout the year.
You might occasionally see this plant listed under its botanical synonym, Eleocharis microcarpa var. brittonii, but Eleocharis brittonii is the accepted name botanists use today.
Where Does It Call Home?
Britton’s spikerush is native to the southeastern United States, naturally occurring across Alabama, Delaware, Florida, Georgia, Louisiana, Mississippi, New Jersey, North Carolina, South Carolina, and Texas. This coastal plain specialist has adapted to life in some pretty specific conditions.
A Conservation Success Story in Your Garden
Here’s where things get serious: Britton’s spikerush is listed as endangered in New Jersey, with an S1 rarity status that means it’s critically imperiled in the state. This makes it not just a beautiful native plant choice, but also a conservation-minded one.
Important note: If you’re interested in growing this rare beauty, please only source it from reputable native plant nurseries that use responsibly collected or propagated material. Never collect plants from wild populations.
