This Season's Shelf

Varieties chosen for short seasons and long winters.

Many of these are Northeast originals — turnips, flint corn, and beans that were bred here generations before us and would have been lost otherwise.

We save it by hand, one season at a time.

Most catalog seed is grown somewhere warm and mild, then shipped north to a climate it has never met. Ours is different. Every variety on this page is selected, roughed, and hand-cleaned on our own beds in Calais — chosen from the plants that shrugged off a late-May frost and still finished before the first hard one in September.

What that means for you: seed with a memory of cold in it. It comes up faster in chilly soil, sizes up in a short window, and doesn't sulk when a Vermont summer forgets to show up.
