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: A budding interest soon to bear fruit?
