Asparagus freezing tolerance related to rhizome traits

Certain cultivars of plants, while growing healthily in their original climates, can suffer from low sustainability when introduced to differing climatic zones. A recent study published in the Journal of the American Society for Horticulture Science analyzed three cultivars of asparagus (Asparagus officinalis), showing that winterhardiness may be directly related to varying levels of water or metabolites within the rhizome of plants.
