Manyseed Goosefoot: An Understated Annual You Probably Don’t Need

If you’ve stumbled across the name manyseed goosefoot (Chenopodium polyspermum var. obtusifolium), you might be wondering if this curious-sounding plant deserves a spot in your garden. The short answer? Probably not—but let’s explore why this unassuming annual exists and what alternatives might better serve your gardening goals.

What Is Manyseed Goosefoot?

Manyseed goosefoot is an annual forb, which simply means it’s a non-woody plant that completes its entire life cycle in one growing season. As a member of the goosefoot family, it’s related to more familiar plants like spinach, beets, and quinoa—though it’s nowhere near as useful in the kitchen or garden.

This particular variety is non-native to North America, having been introduced from Europe. It has managed to establish itself and reproduce without human help in scattered locations across six states: Maine, Maryland, New Jersey, Oregon, Pennsylvania, and Tennessee.

Garden Value: Pretty Much None

Let’s be honest—manyseed goosefoot isn’t winning any beauty contests. Unlike its more glamorous relatives, this plant offers minimal ornamental appeal and doesn’t attract pollinators the way many gardeners hope their plants will. It’s wind-pollinated, which means it doesn’t need to put on a showy display to attract bees or butterflies.

Since specific growing information for this variety is scarce in horticultural literature, it’s safe to say that professional gardeners and botanists haven’t found it particularly noteworthy or useful for cultivation.

Why You Might Want to Skip It

While we don’t have information suggesting manyseed goosefoot is invasive or harmful, there are compelling reasons to look elsewhere for your garden plants:

  • Limited aesthetic appeal
  • Minimal wildlife benefits
  • Takes up space that could support native plants
  • Difficult to find reliable growing information

Better Alternatives: Native Plants That Actually Help

Instead of manyseed goosefoot, consider these native alternatives that will truly benefit your local ecosystem:

  • Wild bergamot – A beautiful native that attracts bees and butterflies
  • Purple coneflower – Gorgeous blooms plus seeds for birds
  • Black-eyed Susan – Cheerful flowers and excellent wildlife support
  • Native sedges – Provide habitat and food for countless species

The Bigger Picture

Every plant choice in your garden is an opportunity to support local wildlife, pollinators, and ecosystem health. While manyseed goosefoot isn’t necessarily harmful, it’s not particularly helpful either. When you choose native plants instead, you’re creating habitat, providing food sources, and supporting the intricate web of life that makes our local environments thrive.

So next time you’re plant shopping, skip the manyseed goosefoot and reach for something that will make both your garden and your local ecosystem a little more vibrant. Your resident birds, bees, and butterflies will thank you!
