Creole garlic bulbs tend to have up to 12 cloves and range from a beautiful light pink to an almost purple glow. Unlike the rosy varieties of hardneck garlics, the entire bulb itself tends to be pink/red/purple. Some types are Cuban Purple, Ajo Rojo, Burgundy, Creole Red, and Rose du Lautrec. This type of garlic tends to have some heat to its flavor and the pungency varies depending on the variety you buy.
Hardneck garlic (Allium sativum ophioscorodon) tend to have more flavor than their soft-necked cousins. They're characterized by hard woody central stalks and a long flower stalk (scape) that loops and curls, usually twice. They tend to have four to twelve cloves in each bulb.
