Callaloo the dish, originates in West Africa where the greens were domesticated. It is also cherished in many parts of the Caribbean. We originally got our seed from Michael's Edible Plant Project many years ago. Two years ago, we sent a sample by request to Southern Exposure Seed Exchange and they trialed it with other varieties, liking this one the best. They now offer it in their seed catalog! Our plants grew up to 10' tall! But if you harvested them more or topped them, they would likely stay a more reasonable size. Space 18" apart and succession plant through the season for continual supply if you harvest frequently. The beetles like callaloo too, so be prepared. They readily self seed which is a good thing in our books, but some don't like that they can then be growing everywhere in no time!
