Smith’s Bulrush: A Rare Native Sedge for Wetland Gardens
Meet Smith’s bulrush (Schoenoplectiella smithii), a charming little sedge that’s perfectly at home with its feet wet! This native annual might not win any beauty contests, but it plays a crucial role in North American wetland ecosystems and could be just what your rain garden or pond edge is missing.
What is Smith’s Bulrush?
Smith’s bulrush is an annual sedge—think grass-like but in the sedge family (Cyperaceae). You might also see it listed under its scientific synonyms like Scirpus smithii, but don’t let the name changes confuse you. This little plant completes its entire life cycle in one growing season, making it quite different from its perennial bulrush cousins.
Where Does It Come From?
This native gem calls eastern North America home, naturally occurring from southeastern Canada down through the northeastern and mid-Atlantic United States. You’ll find it growing wild in states from Maine to Virginia and west to Minnesota and Iowa, plus parts of eastern Canada including New Brunswick, Ontario, and Quebec.
A Plant That Loves Water
Here’s where Smith’s bulrush gets really interesting—it’s what botanists call an obligate wetland species. This means it almost always grows in wetlands and really, really loves having wet feet. Whether you’re in the Great Plains, the Eastern Mountains, or anywhere in between, this plant is telling you the wetter, the better!
Why Grow Smith’s Bulrush?
You might be wondering why anyone would want to grow such a small, inconspicuous plant. Here’s the thing—sometimes the best garden plants are the ones that do important work behind the scenes:
- Perfect for rain gardens and bioswales where you need plants that can handle soggy conditions
- Adds authentic native character to naturalistic wetland plantings
- Self-seeds readily, helping to establish natural-looking plant communities
- Supports local ecosystem health as part of native plant communities
Important Rarity Alert!
Before you rush out to find seeds, here’s something crucial to know: Smith’s bulrush is considered rare in some areas. In New Jersey, for example, it has a rarity status of S2, meaning it’s imperiled in the state. If you’re interested in growing this plant, please make sure you source it responsibly from reputable native plant nurseries—never collect from wild populations.
