Perennial ornamental edible variety, very hardy to Zones 2-8 and salt-tolerant with multiple uses for gardens and landscape. Also known by common names as Oysterleaf, Oysterplant and Sea bluebells. This edible plant for gourmets has silver-blue, greenish crispy leaves with the savory taste of fresh oysters. It requires vernalization over winter to initiate flower bud production. The low spreading habit makes it ideal for rock gardens, hanging baskets and mixed containers.
