Plant of the Week ~ Oxalis tuberosa (Oca)

This week we take a look at an unusual but very underrated herbaceous perennial ~ Oxalis tuberosa (Oca).  Sprouting distinctive, clover-like leaves in spring, with crimson stems, oca makes for an attractive plant even when not in flower.  Warm yellow flowers will bloom from mid to late summer, inspiring joy for anyone who notices them.
