Amazing Oyster Flavor! (M. maritima) This delicious plant is aptly named for its tolerance to maritime exposure and can be found growing wild along the Scottish coast. It received its common name because the thick, tender leaves taste similar to oysters with a hint of seaweed flavor. Perfect in salads and other raw dishes. Because of its beauty and hardiness, some gardeners say they will never be without this amazingly aromatic plant in their garden. Hardy to zone 3; seeds can take a month to germinate. Hard to find!
