We rate every variety by the coldest night it has actually come through, at our two Montana sites in Missoula and Florence or with trusted growers farther north, not by a catalog average. A bare zone number means the whole zone, colder half included. A b, like 5b, means the warmer half only.

Because our ratings come from Montana winters, a plant we rate to zone 3 or 4 has real margin in zone 5. That margin pays off in the test winter every zone gets sooner or later.

With winter cold out of the way, choose for flavor, ripening season and what you want to make. Our ripening maps help you spread the harvest out, the pollination maps show which varieties pollenize each other, and Shop by Use sorts everything by what it's good for.

Other zones: Zone 4 · Zone 6. Find your zone with our cold hardiness calculator.
