A woodsorrel from Bob in SC

Posted on |

Small trifoliate volunteer in the uncultivated portion of yard. Blossom is about the size of a half-dollar. Before it blossomed I assumed it was clover, but was I fooled.

Hi Bob,

this is Oxalis rubra, the windowbox woodsorrel, a commonly cultivated and escaped species often mistaken for shamrocks or clover. Yours is a larger than usual cultivar.  It has an underground corm, looking like a small bulb, and can be propagated by these. A similar species is the native Oxalis violacea.

I hope this helps.
