Winter Hardiness — Common Heather
Calluna vulgaris (L.) Hull
The winter hardiness of common heather (Calluna vulgaris) is characterized by high adaptability to frost down to -28.9 °C, which corresponds to USDA Hardiness Zone 5. This indicator determines the crop's ability to withstand climatic conditions under which other species may suffer significant damag…
In the reference 21 varieties crop Common heather, where this is mentioned in the description.
Wild forms of common heather are distinguished by high frost resistance; however, for garden cultivars, the values range from -20 °C to -30 °C. When temperatures drop below critical levels, the plant may suffer tissue damage, which requires evaluating survival rates in the context of specific climatic zones.
In horticultural practice, winter hardiness is often dependent on agrotechnical factors, including timely preparation of plants for the dormant period. To increase frost resistance in the autumn, potash-phosphate fertilizers are applied, and optimal soil moisture is maintained until the ground freezes.
In northern regions, garden forms of heather require additional protection for the root system using peat, leaf litter, or spruce branches. The lack of standardized quantitative scales for this crop makes winter hardiness a qualitative characteristic, reflecting a cultivar's ability to adapt to local conditions.
