Hardiness Zone 5 - Plants
USDA Hardiness Zone 5 has average annual minimum winter temperatures of -20°F to -10°F (-28.9°C to -23.3°C). Cold winters make hardiness an important consideration, but gardeners can still choose from an impressive range of trees, shrubs, perennials, bulbs, and annuals.
What grows well in USDA Zone 5?
Zone 5 supports many classic temperate-garden plants, including flowering perennials, spring bulbs, deciduous shrubs, shade trees, ornamental grasses, and productive edible plants.
Cold tolerance varies by species and cultivar, so check individual plant hardiness rather than assuming every member of a genus will tolerate Zone 5 winters.
Best trees and shrubs for Zone 5
Trees and shrubs provide the permanent framework of the garden, adding shade, screening, flowers, fall color, bark, and winter structure.
- Trees: Paperbark Maple (Acer griseum), Pin Oak (Quercus palustris), River Birch (Betula nigra), Sugar Maple (Acer saccharum), and other hardy Maples, Oaks, and Birches.
- Shrubs: Ninebark (Physocarpus opulifolius), Hydrangeas, Spireas, Lilacs, and suitably hardy Boxwoods.
Some Butterfly Bush cultivars can also be grown in Zone 5, although hardiness varies and winter dieback may occur.
Best perennials and flowers for Zone 5
Cold-hardy perennials can return for years and create color from spring through fall.
- Perennials: Black-Eyed Susan, Russian Sage, Peony, Coneflowers, Hostas, and Daylilies.
- Annuals: Sweet Alyssum, Impatiens, and Verbena can provide additional seasonal color.
Add early color with spring-flowering bulbs
Fall-planted bulbs are among the easiest ways to bring color back to the garden after a Zone 5 winter.
Daffodils, Tulips, and Crocuses can create displays from late winter through spring, depending on cultivar and local climate.
Look beyond hardiness before planting
A Zone 5 rating indicates that a plant should tolerate typical winter minimum temperatures, but it does not tell you whether the plant suits your sunlight, soil, moisture, summer heat, or local microclimate.
Choose plants according to all of their growing requirements, and favor locally appropriate native plants where possible to support pollinators, birds, and other wildlife.
