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…
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.
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.
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…
