In the 1990's, the "fagiolina" of Trasimeno Lake risked to disappear. The risk has been avoided only thanks to the growing synergy between some farmers, the University of Perouse and the Provincial Authority of Perugia.

Today, only 4 or 5 farmers are growing "fagiolina"; all the others have been discouraged by the laboriousness and long time needed for its growing and the manual sowing and threshing.

Sowing take place in springtime, the ripening is graded and the long manual arvesting begins in June ending at the beginning of October.

Then, the pods are sun-dried and threshed with hay-forks and sticks; afterwards, seeds are winnowed and finally the fagiolina is put into hempen cloth bags
