Grew my own garlic for the first time this year. I came out really well. We got 43 bulbs and they are tied and drying now. I will be doing this again for sure.
I have garlic chives, Allium tuberosum, growing as a major nuisance weed in my back gardens. It has the "walking onion" habit. I can harvest the bulbs, harvest the fresh greens, and the bulblets that form out on the stem.
I haven't had much luck growing regular garlic, though.

Ah, we can all dream. I have never been able to eradicate the stuff. Fortunately I'm a garlic lover so I can ravage the stuff to make something like garlic salt, and never exhaust the resource.
