Giant Sea Kale

Giant Sea Kale

A monstrous cousin of the more commonly seen Sea Kale, the Giant Sea Kale (Crambe cordifolia) is valued as both a bold and bodacious ornamental as well as a very useful perennial vegetable. It can be harvested for its young leaves, flower buds in the “broccoli” stage as well as flowers and roots. Grows as a large perennial mound 1.5′ to 2′ tall with flower stalks that can reach up to 4 feet tall or more. A very fun and exciting perennial vegetable to add to the garden.
