Verdolino bean is a traditional legume of Upper Tuscia. The seed of this local ecotype is reproduced in the few holdings still cultivating it. It is sown in the first half of May and the harvest takes place between mid-May and the first days of August. Verdolino bean has a spherical shape, a grey-green color, and a medium size. It has been added to the Register of Threatened Genetic Resources, since it is not very widespread, and only in the Province of Viterbo. It is produced by some agricultural holdings with organic agriculture methods.
