Annual Rocket (Eruca sativa) is a spicy salad leaf which is very easy to grow. Added to salads and sandwiches for a peppery kick and often lashed onto pizzas for some reason. It is best to sow larger amounts early or late in the season as the long days of summer cause it to bolt very quickly. The flowers make a nice edible garnish though and provide food for pollinators so how bad. During the summer it could be planted little and often. Very cold hardy.
