Winter hardiness is an important consideration when planning your garden. Deciduous trees, bulbs, shrubs and perennials are winter-resistant while annuals die off by the first frost. Just because a plant is a perennial does not mean it will thrive under all weather conditions.
Be sure you plant in well-drained areas as root rot is a common reason plants do not survive the winter. Even winter-hardy plants can perish if their roots remain wet.
