Two types of Arugula (also known as rocket, rucola, roquette) grow very easily in the Caribbean. Both are pungently peppery, especially when the weather is hot and dry. They make a fine addition to salads, avocado, and cooked dishes. While both are members of the Brassicaceae (mustard) family and require similar growing conditions, there are some differences that might help you choose one over the other. Both are ready to begin harvesting within a month.
