Pla de Grau is a large area of protected fields used for growing, mainly, vegetables, such as potatoes, lettuce, curly endive, tomatoes and Ganxet bean. The commercialisation of the produce from Malgrat de Mar (specifically from Pla de Pineda and Pla de Grau) and other crop areas in the nearby towns of Palafolls, Santa Susanna and Blanes is led by the agricultural cooperative Progrés-Garbí. This cooperative was born in 1992, as a result of the merger between the two cooperatives El Progrés and Garbí.
Two of the key products grown in Malgrat de Mar are Ganxet beans and curly endives.
- Fesol del Ganxet (Ganxet beans) was awarded the label of Protected Designation of Origin (PDO). Most of the produce is sold directly in markets and to restaurants. You can distinguish it by shape: experts say every specimen should be flat, white and with a characteristic hook shape at one end.
- Malgrat de Mar annually exports about 4 million curly endives, its main destination being the French market.
