More famous in the culinary circle as Rocket leaves, arugula leaves are bite-sized tender leaves with a tangy flavour, used primarily in salads. Rich in beneficial nitrates and polyphenols, these herbs are also associated with reducing the risk of cancer, diabetes, and osteoporosis. An annual plant that prefers cooler climate and loves full sun and a well-draining soil, these herbs are easy to grow from seeds and often prove to be wonderful garden plants.
