I'm not that knowledgeable about garlic but was given a local heirloom start of garlic years ago. It is planted and left in ground as a perennial. It is dug only as needed. You will find patches of it growing wild in ditches or pastures.
The elderly man that shared with me told me that the old timers believed it also repelled snakes so they would plant around chicken pens, etc.
Winter grower here. It puts on new growth in October, growing through winter, scaping in May and the foliage dying back in June for approximate seasons.
