SUPER HARDY PLANTS
In this section we bring together our selection of super hardy plants for our cold climate gardeners in zones 1 through 4. Remember that if you mulch your plants with fallen leaves or straw, have good, reliable snow cover, plant in warmer microclimates in your garden, and cross your fingers, you might be able to grow plants rated as one zone warmer than your hardiness zone. Also, city gardens are often one zone warmer than the official hardiness zone for that region. Have fun pushing the limits!
