Garden rocket, also called rocket lettuce, is an annual plant that belongs to the Brassicaceae (cruciferae). This plant is also cultivated as arugula lettuce.
Garden rocket can be used as green manure, but produces much less biomass than, for example, radish or white mustard. It is a bad host plant for most harmful nematodes. Garden rocket is therefore an ideal crop to serve as a mixing partner for mandatory blending by the government.
