Zone 2a is located in north continental United States and Alaska. The climate is classified as Dfb by the Köppen-Geiger system. Planting Zone 2 (a & b) features very harsh winter conditions with average minimum temperatures of between -50 to -40 degrees F. High winds, snow and drought conditions are also a great challenge. Creative planting techniques, hot houses and early planting in pots and seed trays are required for successfully growing vegetables and herbs. Very few perennial vegetables will work in Zone 2. Best to choose annual vegetables with a short growing season for the best results. Some possible vegetables are: Swiss chard, Carrots, Mustard greens, Parsnips and Onions. Some herbs worth considering are: Hyssop, Juniper, Turkestan Rose.
