The white grape variety comes from Italy. Synonyms are Bianca, Don Lunardo, Lunardo and S. Lunardo. It is native to the Campanic island of Ischia in the Bay of Naples. Although it was not mentioned until 1962, it has certainly been around much longer. The name probably refers to San Leonaordo, the patron saint of the city of Panza. According to DNA analyses carried out in 2010, the variety is the result of a presumably natural cross between Albana Bordini (red) and Biancolella (white). The vine is resistant to botrytis. It is cultivated in the province of Naples in Campania, where it is permitted in the DOC white wine Ischia. In 2016, 4 hectares of vineyards were designated with a decreasing trend (Kym Anderson).
