Oxalis enneaphylla, or scurvy grass, is a late spring- and summer-flowering, rhizomatous, alpine perennial herbaceous plant native to the grasslands of Patagonia and the Falkland Islands.

Sailors travelling around Cape Horn would consume the leaves to avoid scurvy.

This is illustrated by this extract from the Journal of Syms Covington, who sailed aboard HMS Beagle with Charles Darwin.

Here he describes the Falkland Islands, and refers to Oxalis enneaphylla as "wild thyme": While laying here we found it very squally, and at times very cold.

The species[3] and the hybrid cultivar 'Ione Hecker'[4] have gained the Royal Horticultural Society's Award of Garden Merit.
