Oxalis triangularis (syn. subsp. papilionaceae) on 2-15-19, #547-2.

Oxalidaceae R. Br.

The plant family Oxalidaceae was named and described as such by Robert Brown in Narrative of an Expedition to Explore the River Zaire in 1818. James Hingston Tuckey is listed as an “In Author”.

As of 12-21-23 when this page was last updated, Plants of the World Online still lists 5 accepted genera in this family commonly known as the wood sorrel family. There are a total of 667 accepted species listed between them with the genus Oxalis being the largest with 566 species. Genera include Averrhoa (5 species), Biophytum (81 species), Dapania (3 species), Oxalis (566 species), and Sarcotheca (12 species). Those numbers could change as updates are made on POWO. The only genus I am familiar with is Oxalis.

Oxalis articulata (syn. subsp. rubra) (Pink Wood Sorrel) flowers on 3-22-09, #8-16.

I found a few Oxalis articulata (syn. subsp. rubra) (Pink Wood Sorrel) growing in the yard at the mansion when I lived in Mississippi. I put a clump in one of the planters…

Oxalis tetraphylla in a friend’s planter on 8-1-21, #822-21.

I have grown Oxalis tetraphylla (Iron Cross, ETC.) for several years and I really like their green and maroon leaves. I do a friend’s planters and thought one would look great in his boot by the front porch.

Oxalis triangularis (syn. subsp. papilionaceae) on 6-16-19, #591-37.

My first start of an Oxalis triangularis was given to me by a friend in 2012 when I lived in Mississippi. When I moved back to the family farm in 2013, I found a pot of Amorphophallus at a local greenhouse with one growing in the pot. SO, that’s the pot I brought home. It had MUCH larger leaves and after some research found it was likely the subspecies Oxalis triangularis subsp. papilionaceae. Well, the subspecies is now a synonym of the species. This plant has multiplied A LOT and I now have several pots. If I keep them watered over the winter they don’t go dormant.

The green Oxalis triangularis on 8-18-21, #827-27.

Then in 2021, the local grocery store had several purple and green Oxalis triangularis available. I just had to bring a green one home. They have white flowers instead of pink.

That’s all I have experience with for the plant family Oxiladaceae. Well, besides the Yellow Wood Sorrel that grows in the yard and flower beds. I don’t have a page for that species yet and I need more photos…
