Chives are one of the few herbs that will make it indoors in the winter. We get a little angry when we see all those herbs advertised that thrive magically in little pots on your windowsill. It just doesn't happen. They will be fine for about a month and then unless you have a very strong light source they will slowly expire. Chives on the otherhand will see you through the winter.They can be divided in the spring or fall. But if you let chive flowers go to seed they can be a bit too enthusiastic in your garden.
