A broccoli-like vegetable with large, densely packed, usually blue green heads and few outer leaves, originally from Calabria. It may be white, green or purple. Sprouting broccolis have masses of small florets growing over a long season, while calabrese is a summer vegetable with a heavy central head. Calabrese, as well as broccoli, can be deep purple, lime green or white. The prettiest are the "Romanesco" types.
