Redwood Sorrel
Oxalis oregana

Redwood sorrel is a lush, clover-leaved groundcover that carpets the floor of Pacific coast forests and folds its leaves in bright light, with dainty pink-white flowers. A superb native for moist, acidic deep shade. The tart, lemony leaves are a favorite raw trailside nibble and salad addition — enjoy in moderation, since their oxalic acid can affect people prone to kidney stones or gout if eaten in quantity.
