Simplestem Bur-Reed: A Wetland Plant with Limited Garden Appeal

If you’ve stumbled across the name simplestem bur-reed (Sparganium erectum stoloniferum), you’re likely wondering what exactly this plant is and whether it deserves a spot in your garden. Let’s dive into what we know about this somewhat mysterious wetland species.

What Is Simplestem Bur-Reed?

Simplestem bur-reed is a perennial forb, which simply means it’s a non-woody plant that comes back year after year. Like other plants in the bur-reed family, it’s designed for life in and around water. The plant has gone by several scientific names over the years, including Sparganium eurycarpum var. greenei and Sparganium greenei, which might explain why information about it can be a bit scattered.

Where Does It Grow?

Currently, simplestem bur-reed can be found growing in several western and a few scattered eastern states, including California, Idaho, Oregon, Vermont, Washington, West Virginia, Wisconsin, and Wyoming. However, here’s where things get interesting – despite its presence in these states, it’s actually classified as a non-native species that has established itself in the wild.

Should You Plant Simplestem Bur-Reed?

This is where honest gardening advice comes in handy. While simplestem bur-reed isn’t listed as invasive or harmful, there are several reasons why you might want to think twice about adding it to your landscape:

  • Limited ornamental value compared to other wetland plants
  • Non-native status means it doesn’t support local ecosystems as well as native alternatives
  • Very specific growing requirements that can be challenging to meet
  • Limited availability from nurseries and seed suppliers

Better Native Alternatives

If you’re looking to create a wetland garden or add water-loving plants to your landscape, consider these native bur-reed species and other wetland plants instead:

  • American bur-reed (Sparganium americanum) – native and equally interesting
  • Broad-leaved cattail (Typha latifolia) – dramatic and wildlife-friendly
  • Wild rice (Zizania species) – beautiful and beneficial for waterfowl
  • Pickerelweed (Pontederia cordata) – stunning purple flowers

Growing Conditions (If You’re Still Interested)

Should you decide to grow simplestem bur-reed despite the alternatives, here’s what the plant family typically needs:

  • Consistently wet to marshy conditions
  • Full sun to partial shade
  • Rich, organic soils
  • Shallow standing water or saturated soil

Keep in mind that specific growing requirements, hardiness zones, and care instructions for this particular variety are not well-documented, which adds another layer of challenge to successful cultivation.

The Bottom Line

While simplestem bur-reed isn’t a bad plant, it’s not particularly exciting for most gardeners either. With so many beautiful native wetland plants available that offer better wildlife benefits, easier care, and greater ornamental appeal, you’re probably better off exploring other options for your water garden or wetland restoration project.

If you’re passionate about bur-reeds specifically, stick with native species that will better support your local ecosystem while giving you the wetland aesthetic you’re after. Your local wildlife – and your garden – will thank you for it!
