Oca: Flowering good fortune

Oca (Oxalis tuberosa) 'OE Orange' flowering

Flowering OE Orange oca plant in an embarrassingly weedy patch This has been a particularly exciting week for my little oca (Oxalis tuberosa) experiment, which is nice because I am working on a project that is burning out my brain.  Almost every time I head outside for a quick break, I am greeted with some new […]

Oca: Hopin for flowers

Oca (Oxalis tuberosa) variety 'Hopin' flowering

First flower on a Hopin oca plant Yesterday, I wrote of my surprise at finding June flower buds on some of our oca (Oxalis tuberosa) plants.  Today’s events were not quite as surprising, but still unexpected.  We have our first oca flower.  It opened on a plant of the Hopin variety sometime between 10AM and […]

Nutrition facts for oca, ulluco, and mashua

Oca (Oxalis tuberosa) nutrition facts
