Chenopodium gaudichaudianum: An Elusive Member of the Goosefoot Family

If you’ve stumbled across the name Chenopodium gaudichaudianum in your botanical travels, you’re not alone in wondering what exactly this plant is all about. This member of the goosefoot family (Amaranthaceae, formerly Chenopodiaceae) is one of those mysterious species that seems to exist more in scientific literature than in garden centers or field guides.

What We Know (And What We Don’t)

Chenopodium gaudichaudianum belongs to a large genus of plants commonly known as goosefoots or lamb’s quarters. The genus includes everything from edible greens to weedy species, but this particular plant appears to be quite obscure in horticultural circles.

The plant has at least one known synonym: Rhagodia gaudichaudiana, which suggests it may have been reclassified at some point in its taxonomic history. The name gaudichaudianum likely honors Charles Gaudichaud-Beaupré, a French botanist who collected specimens during various 19th-century expeditions.

The Mystery of Distribution

Unfortunately, reliable information about where this plant naturally occurs is not readily available in common horticultural or botanical references. This lack of information suggests it may have a very limited natural range or may be primarily of interest to specialized botanists rather than gardeners.

Garden Potential: Proceed with Caution

Given the limited information available about Chenopodium gaudichaudianum, it’s difficult to recommend it for garden use. Here’s why you might want to consider alternatives:

  • Unknown growth requirements make successful cultivation challenging
  • Unclear native status means you can’t be sure of its ecological impact
  • Limited availability suggests it’s not commonly cultivated
  • Unknown wildlife benefits make it hard to justify in native plant gardens

Better Alternatives in the Chenopodium Family

If you’re interested in plants from this family, consider these better-known options:

  • Lamb’s quarters (Chenopodium album) – Edible and wildlife-friendly, though can be weedy
  • Good King Henry (Chenopodium bonus-henricus) – Historical vegetable with ornamental value
  • Native saltbush species – If you’re in arid regions, look for local Atriplex species

The Bottom Line

While Chenopodium gaudichaudianum certainly exists in the botanical world, it appears to be more of academic interest than garden interest. Without clear information about its growing requirements, native status, or ecological role, it’s hard to recommend seeking it out for your landscape.

If you’re passionate about unusual plants and happen to encounter seeds or plants of this species from a reputable source, approach with curiosity but caution. Start small, observe carefully, and be prepared that it might not thrive in typical garden conditions.

Sometimes the most responsible thing a gardener can do is admit when a plant is better left to the specialists and instead choose well-documented alternatives that we know will succeed and benefit local ecosystems.
