This garlic is not really a garlic, so it’s not any particular type!
This is not a true garlic, and is closely related to leeks. It has 5 cloves, and it’s a little hard to see from the picture but it’s huge. I remember tasting this garlic as a kid, but it was too long ago to remember the flavor. I haven’t tasted this one yet.
If you grow this one be aware that planting stock is often sold as single cloves. It’s taken me 2 times trying to get it to grow, because the first time an animal came along and ate it. Since all I had was one clove, that was it! You might want to consider growing at least 2 of them for this reason.
