An oca tale

Oxalis peduncularis is a member of the O. tuberosum (oca) alliance and
is likewise, I believe, used as a food crop. It is one of the wackiest
plants I've grown, with brassy yellow flowers going off in all
directions from a tree-like stem. I eventually gave up on trying to
fit it in, though it was attractive enough.
