Gai lan, kai-lan, Chinese broccoli,[1] or Chinese kale (Brassica oleraceavar.alboglabra)[2] is a leafy vegetable with thick, flat, glossy blue-green leaves with thick stems, and florets similar to (but much smaller than) broccoli. A Brassica oleraceacultivar, gai lan is in the group alboglabra (from Latin albus "white" and glabrus "hairless"). When gone to flower, its white blossoms resemble that of its cousin Matthiola incana or hoary stock. The flavor is very similar to that of broccoli, but noticeably stronger and slightly more bitter.[3]
