Yep, you read that right - Floppin' Garlic.
In my previous years of growing garlic, I've never had the tops flop over - that has been something only the onions do. This year, however, almost all of the garlic has flopped. Apparently it has to do with growing softneck garlic as opposed to hardneck garlic. And per this article by the Oregon State Extension Office, it looks like it means that the garlic is ready to harvest.
