Calabrese broccoli comes from the province of Calabria in Italy and arrived in America in the 1880s. This richly flavored open-pollinated Broccoli variety is popular with home vegetable gardeners! Green Sprouting Calabrese Broccoli seeds grow quickly and produce 4" heads with abundant side shoots, which can be harvested after the main head has been cut. Maturity time is not uniform, resulting in an extended harvest for home vegetable gardens!
