There are two primary types of garlic. Hard neck, and soft neck. The hard neck types usually have larger cloves, but fewer cloves in each bulb with a stronger flavor. The soft neck types can have a huge cluster of smaller cloves depending on the species, and it is the type they usually sell at stores since they store longer than hardnecks, but they generally have less spice than the hardnecks. I either buy them from bulbils which are kind of like seeds which take another year to reach full size, or I buy the cloves which cost more, but produce full sized bulbs when they are planted in the fall. The thing I love about garlic is that they really take no effort to grow as all I need to do is drop the cloves in the ground during the fall, and harvest them the following summer.
I grow both kinds and many species of them.
