Zone 5 Information
Look for Zone 5 climates scattered across the midsection of the United States. The zone starts in the corner of eastern Washington, drapes down into the Midwest, and then rises up through the edge of New York. Both Newfoundland and Nova Scotia are included in this zone as well. The weather can be brutal in the winter and hot in the summer. Keep your plant choices within the Zone 5 range and your garden will thrive.
Zone 5 was divided in 1990 into two areas by the National Arboretum to provide gardeners with even more environmental detail: 5a and 5b.
5a - Minimum temperature of -20 to -15 F (-26.2 to -28.8 C) Places like Des Moines, Iowa and Illinois.
5b - Minimum temperature of -15 to -10 F (-23.4 to -26.1 C) Places like Columbia, Missouri and Mansfield, Pennsylvania.
Here's a partial list of plants that thrive in Zone 5
Pink Flowering Almond(Prunus glandulosa)
Adams Crabapple(Malus 'Adams')
Grape Hyacinth(Hyacinthus orientalis 'Gypsy Queen')
