The scapes can be cut and used as you would garlic. If left on the plant each scape will produce little round mini-bulb seeds. It takes about three years to get a good-sized garlic head from the scape seeds. You can also grow garlic from individual cloves planted in summer/fall and get full-sized garlic heads the following spring.
All of this garlic began with a handful of little garlic seeds given to us by some good friends. We planted the seeds in 2010.
Soon we will dig up some heads of garlic and see it in yet another form!
