You will receive a seed packet containing 1 gram or a minimum of 500 fresh arugula seeds. Eruca Vesicaria, also known as Arugula, rocket, or roquette are common names used to refer to this member of the brassica family. Though it is not technically lettuce, being more closely related to mustard greens or kale, it is loved all over the world for its unique peppery flavor. No matter what you call it, growing fresh greens from seed is a fun, easy way to get excited about adding more vegetables to your diet. The narrow-lobed leaves are tender when harvested young and are fantastic for arugula salads, wraps, or added to any dish that needs a fresh kick.
