Wood Sorrel (Oxalis, Yellow Sorrel, Pink Sorrel, Creeping Wood Sorrel)

• Common Name: Wood Sorrel (Oxalis, Yellow Sorrel, Pink Sorrel, Creeping Wood Sorrel)
• Latin Name: Oxalis spp.
• Family Name: Oxalidaceae

All of the sorrels from the Oxalidaceae family contain high amounts of oxalic acid, and although a small nibble will do no harm it is best avoided as it could bind with calcium and cause kidney stones or gout.

Also grown as a garden plant.  The leaves of Wood Sorrel can easily be confused with Clover, but the flowers are very different.

Oxalis acetosella (Common wood sorrel); Oxalis stricta (Yellow wood sorrel); Oxalis corniculata (Yellow Sorrel); Oxalis articulata (Pink Sorrel).
