Spiral Sorrel: The Mysterious Oxalis spiralis

If you’ve stumbled upon the name spiral sorrel or Oxalis spiralis in your gardening research, you might be wondering what exactly this plant is and whether it belongs in your garden. Well, you’re not alone in your curiosity – this particular member of the wood sorrel family is quite the botanical mystery!

What We Know About Spiral Sorrel

Oxalis spiralis, commonly known as spiral sorrel, is a member of the Oxalis genus, which includes hundreds of species of small flowering plants. However, here’s where things get interesting (and a bit frustrating for us plant enthusiasts): reliable information about this specific species is remarkably scarce in current botanical literature.

The Challenge with Oxalis spiralis

Unlike its more famous cousins like wood sorrel (Oxalis stricta) or shamrock (various Oxalis species), spiral sorrel seems to fly under the radar. This could mean several things:

  • It might be an extremely rare species with limited distribution
  • The name could be a regional common name for another Oxalis species
  • It may be a taxonomic name that’s fallen out of current use
  • Documentation about this species might be limited to specialized botanical sources

Geographic Distribution

Unfortunately, the native range and current distribution of Oxalis spiralis remain unclear based on available sources. This lack of information makes it difficult to determine where this plant naturally occurs or whether it’s suitable for cultivation in various regions.

Should You Try to Grow Spiral Sorrel?

Given the limited information available about Oxalis spiralis, it’s challenging to provide specific growing recommendations. If you’re interested in adding wood sorrel-type plants to your garden, you might want to consider these well-documented alternatives:
