Sorrel (Oxalis regnellii): A Lesser-Known Member of the Wood Sorrel Family
If you’ve stumbled upon the name Oxalis regnellii in your plant research, you’re likely looking at one of the more elusive members of the wood sorrel family. While many Oxalis species are well-documented garden favorites (or notorious weeds, depending on your perspective!), this particular sorrel presents something of a botanical mystery.
What We Know About This Sorrel
Oxalis regnellii belongs to the diverse Oxalis genus, which includes hundreds of species worldwide. Like its relatives, this sorrel likely shares the characteristic three-leaflet leaves that fold up at night or in response to touch – a charming feature that never fails to delight gardeners and curious kids alike.
The Challenge with Identification
Here’s where things get interesting (and a bit frustrating): reliable information specifically about Oxalis regnellii is surprisingly scarce in mainstream horticultural literature. This could mean several things:
- It might be a regional name or variant that’s not widely recognized
- It could be a species that’s rarely cultivated in gardens
- The name might refer to a plant that’s been reclassified or merged with another species
Native Status and Distribution
Unfortunately, the native range and distribution of Oxalis regnellii remains unclear from available sources. Without this crucial information, it’s impossible to determine whether this plant would be a good native choice for your garden or if it might pose any invasive risks.
