In reply to "can I just leave it in the ground or do I have to harvest and plant again?" I thought I had some cute flowers growing in my back yard of a rental that we live in. Every year they come up and are really pretty. This year I decided to take a closer look, I thought they were onions maybe, having not grown onion since I was 6 in my mom's garden I couldn't remember. I decided to dig one up and see how big it was, since its been there for almost 4 years and who knows how much longer before we lived here. That's when I learned it was garlic, not onion. They are small heads but it is early June here in So. Utah, so they do just keep growing back year after year, but I don't know the quality.
