Sedano nero di Trevi is a traditional type of celery that's been grown in Trevi in the province of Perugia since the 17th century. The characteristics of this so-called black celery are its dark-green ribs, the absence of fibers, its long length (up to 1 meter), and the intense fragrance.
The sowing takes place in April during the waning moon, and in mid-October, the harvest is ready to take place and lasts until November. The intense flavor of Trevi's black celery is used in local cuisine and dishes such as stuffed celery, pinzimonio, and black celery parmigiana.
