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. Just like Sea Kale, the Giant Sea Kale 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.
