Yes but you will not be happy with the result. Each clove produces a
new plant which develops a head full of cloves. So if you leave a
head in the ground with 10 cloves in you will get 10 plants which will
each try to produce a new head. The proxomity of all these plants to
one another will prevent the development of any useable garlic.

Dig 'em.
