Rank ReasonsOxalis violacea is a perennial herb found in a variety of habitats including glades, rocky outcrops, bluffs, bottomlands, forests, woodlands, roadsides, old fields and disturbed sites of eastern North America from Vermont and Massachusetts west to North Dakota south to Florida and Texas in the United States, and it is also in Mexico. Threats include development, recreation, invasive species, succession, rights-of-way maintenance, and deer browse. With a large range extent, more than 5,000 occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsOxalis violacea is native to eastern North America from Vermont and Massachusetts west to North Dakota south to Florida and Texas in the United States, and it also occurs in Mexico (FNA 2016). Range extent was estimated to be over 5 million square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens and photo-based observations documented between 1993 and 2024, it is estimated that there are over 5,000 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Oxalis violacea is threatened by development, recreation, invasive species, succession, rights-of-way maintenance, deer browse, and other threats in some places (NatureServe 2024); though there is insufficient data, including anecdotal accounts, to understand the scope and severity of threats for this species.
