You can freeze them though they can tend to be mushy when thawed. If you want to freeze them, cut them into pieces about an inch long, blanch for about a minute, plunge into icy water to stop them cooking. Dry them thoroughly, put them into freezer bags, suck out as much air as you can from inside the bags, seal the bags and put into the freezer.
I think they're best frozen by turning them into a soup and freezing the soup
