Having brought the two large pots of dormant Oxalis regnellii 'Purpurea' up from the basement and repotted them I have a plethora of extra tubers. I have eaten wood sorrel leaves, also oca.
Does anyone know if any portions of the purple leaf oxalis are edible?

Oxalis tuberosa This vegetable originated from the Andes of South America. It ranges from pale creamy-white to deep purplish red in colour and sweet to slightly astringent in taste, depending on variety. It is a popular root crop of the Andes. It is easy to prepare, as it does not require peeling, however, as it is a root crop, proper cleaning is essential before roasting, steaming or frying.

Gophers will eat this root, bulb, leaf, and flower...but perhaps you are not a gopher.
I think the only toxicity in Oxalis is the oxalate crystals?
Some data from the USDA only mentioned non-food using method. (It should be in relatively very small dose.)

Thank you for your research efforts, fierycloud, and comment, Robert. Not that I'm especially interested in eating this oxalis. Merely that there is an excess of it. I have used various garden plants and weeds as foraged ingredients: fiddlehead ferns, garlic mustard, Petasites, etc. Not geophytes - never had an excess of tulips and the so-called fairy spuds, Claytonia virginica, are both attractive and so tiny that I'd be digging for a long time for a single serving.
Looking for general info about Oxalis regnellii 'Purpurea' I found this on TopTropicals.com catalog: "As a spice or herb, it is used to flavor lemony dishes or to add a splash of vibrant pink or white hues to salads."
Moderation in all things . . .
After the years of biological news about virus such as RNA fragment being positive or whole virus which could be propagated in a live cell. I suddenly wonder that if the plants which have less ingredient which human body consist of or could be digested or absorbed by human might be less possibility to nourish the microorganism in viro than the edible landscape. I wonder if the plants have the form and quantity of the carbohydrate, protein, fat which could be digested or absorbed by human could be more possibility to nourish the bacterial and fungi adaptive to the human food and ingredient outside the human body than the plants which have only small amount of carbohydrate, protein, fat or not the form used by human.
