It seems to vary a lot by variety - some varieties in-ground are precocious and start bearing the first season (Violette de Bordeaux and related, Mt. Etna types, Zingarella-RW, Siclilian Red, etc) while others are not (Ponte Tresa, Scott's Black, Briguglio, Bordissot Blanca, Vasilika Sika-Belleclare, Battaglia Green, Kathleen's Black, Pastiliere etc.). Some will also not produce after experiencing winter die-back while others will recover and produce a crop the same year.
