Will someone please explain to me why more people aren’t growing the amazing sea kale, Crambe maritima. This amazing perennial is a great tasting green that returns every year without replanting. It’s also a great flowering perennial, putting on a show now in our rock garden. We have also never seen any pest activity such as typically bothers other members of the cabbage family. Our plant is growing in half-day sun in pure gravel (in our crevice garden), and never receives any supplement irrigation. The economic return from Crambe maritima is huge. I guess some folks may not find it attractive, but darn, folks!
Blooming now in the crevice garden is one of our favorite edimentals. If you haven’t heard this word before, it’s the new combo term for edible ornamentals. Crambe maritima, known as sea kale, is a plant we first grew for its fragrant flowers, only to find it incredibly tasty, both fresh and cooked. We are constantly grabbing a leaf for a garden snack. Best of all, Crambe maritima is a perennial that doesn’t need to replanted yearly. We can’t imagine why every lover of kale doesn’t grow this. Dry full baking sun is all that’s required.
When we finally discovered that sea kale (Crambe maritima) is indeed growable in our hot, humid climate, we’ve planted it all around. It’s also been rewarding that people have actually purchased it to try for themselves. Frankly, I’d grow sea kale for the ornamental value alone…a perennial with blue waxy foliage and an incredible show of white flowers in spring! Then, there’s the edibility, both cooked and raw. Also, for us, unlike other cabbages and kale, it has been virtually untouched by the pesky cabbage loopers.
Here is a photo of sea kale in our crevice garden this April, growing in a soil mix that’s 50% gravel, with no summer irrigation. Read my lips, I mean text…full baking sun and no irrigation after establishment. We recommend you never let your plants read the repetitive on-line sites that all tout that it only grows in cool, moist, climates…hooey!
