Beside this, are all types of oxalis edible?
Oxalis literally means "sour" and it gets that name from its oxalic acid content. Lots of domesticated vegetables, including spinach, broccoli, and, um, sorrel, also contain oxalic acid. All parts of wood sorrel are edible including leaves, flowers, seed pods, and roots.
Besides, is Oxalis triangularis edible?
Oxalis triangularis, commonly called false shamrock, is a species of edible perennial plant in the family Oxalidaceae. It is native to several countries in southern South America. This woodsorrel is typically grown as a houseplant but can be grown outside in USDA climate zones 8a–11, preferably in light shade.
Oxalis is actually an excellent plant for bees and butterflies. When blooming, it provides “copious nectar.” In fact, it generously gives away its nectar. Since it doesn't set seed, it doesn't benefit from pollinators – but it's a food source for honey bees, bumblebees and butterflies.
