CERTIFIED ORGANIC! Dark green plants grow 45-75cm (18-30") tall with a tightly beaded bluish green central head between 8-20cm (3-8") across. This is followed by abundant side shoots that keep coming until frost. Sow Calabrese organic broccoli seeds in early March indoors, or in May and June for a fall harvest. This heirloom broccoli variety arrived in North America with Italian immigrants in the late 1880s. It is probably centuries old. It's a reliable open pollinated broccoli for the home grower or market, and it can be stored by canning or freezing if any is left in your garden from fresh harvest eating.
