Plant hardiness is the ability of a plant to survive adverse growing climates such as drought, flooding, heat and cold. The science behind plant hardiness can be complicated. Plant genetics determine the ability of a plant to withstand cold temperatures without damage. Each cultivar of a plant may have different hardiness levels based on their adaptations and genetics. Even different parts of a plant may be hardy in different ways. For example, the cold may cause your beloved perennial to die; however, the roots might be hardy enough to bring new growth in the spring. It is well-suited for light (sandy) and medium (loamy) soils and can even grow in nutritionally poor soil.
