Flatstem Spikerush: A Native Sedge for the Adventurous Gardener
If you’re looking to add some authentic native character to your landscape, let me introduce you to flatstem spikerush (Eleocharis compressa var. compressa). This unassuming little perennial might not win any beauty contests, but it’s got some serious native credentials that make it worth considering for the right garden situation.
What Exactly Is Flatstem Spikerush?
Despite its name suggesting it’s a rush, flatstem spikerush is actually a member of the sedge family (Cyperaceae). It’s what botanists call a graminoid – basically a fancy way of saying it’s grass-like in appearance and behavior. This perennial native has been quietly doing its thing across North America for ages, and it’s got the distribution to prove it.
Where You’ll Find It Growing Wild
Flatstem spikerush is a true North American native, calling both Canada and the lower 48 states home. Its range is impressively wide, stretching across numerous states including Alabama, Arkansas, Colorado, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Nebraska, New Jersey, New Mexico, New York, North Dakota, Ohio, Oklahoma, Pennsylvania, South Dakota, Tennessee, Texas, Virginia, West Virginia, and Wisconsin. It also grows in Ontario and Quebec.
Should You Plant It in Your Garden?
Here’s where things get interesting – and a bit challenging. Flatstem spikerush is definitely a plant for the more adventurous native gardener. As a sedge, it brings authentic native plant diversity to your landscape, which is always a plus for supporting local ecosystems.
However, I’ll be honest with you: this isn’t a plant with a lot of readily available growing information. It’s one of those if you know, you know kind of natives that tends to fly under the radar in most gardening circles.
The Reality of Growing Flatstem Spikerush
If you’re considering adding this native sedge to your garden, you’ll need to be prepared for some detective work. Here’s what we do know:
- It’s a perennial, so once established, it should return year after year
- As a sedge, it likely prefers consistently moist conditions
- Its wide native range suggests it’s fairly adaptable to different climates
- Being a graminoid, it probably works well in naturalized or wetland garden settings
A Plant for Patient Gardeners
The truth is, flatstem spikerush might be better appreciated by those who love the idea of growing lesser-known natives rather than gardeners looking for immediate visual impact or detailed growing guides. Its value lies more in its ecological authenticity than its ornamental appeal.
If you’re drawn to this plant, your best bet is to observe it in its natural habitat first. Pay attention to where it grows, what conditions it seems to prefer, and what other plants it associates with. This field research will give you the best clues for recreating suitable conditions in your own landscape.
The Bottom Line
Flatstem spikerush represents the kind of native plant that keeps dedicated native gardeners on their toes. It’s not going to be the star of your garden show, but for those committed to supporting truly local plant communities, it offers the satisfaction of growing something authentically regional.
Just be prepared to become something of a plant detective if you choose to grow it – and consider that part of the adventure rather than a drawback. After all, some of the most rewarding gardening experiences come from working with plants that make you slow down and pay attention to what they’re really trying to tell you.
