Oxalis enneaphylla, the scurvy-grass sorrel, is a late spring- and summer-flowering, rhizomatous, alpine perennial herbaceous plant native to the grasslands of Patagonia and the Falkland Islands. It is a small plant that grows to 7 cm (2.8 in) high and 10 cm (3.9 in) across, with slightly fleshy, hairy, blue-grey leaves, which are edible but have a sharp taste due to their high oxalic acid content. The name enneaphylla comes from the Greek εννεα (ennea), "nine" and φυλλον (phyllon), "leaf".
