Oyster Leaf. The leaves are edible and taste - and feel - exactly like raw oysters. If raw oysters are your thing, this is an OMG veg alternative. The now closed El Bulli in Catalonia, regarded as one of the greatest restaurants ever, ran with Oyster Leaf innovative ways. Loved to have tried the leaves striped in golden caviar and splashed with Grey Goose. Beautiful glaucous blue-green leaves on sprawling stems tipped in small sky blue flowers. This likes ample nutrition. Perennial and dormant in winter. This is a plant of just above high tide line on cold northern hemisphere beaches from Maine to Greenland and Japan to Alaska so if you have a cool to cold garden, here you go.
