Variety traits
Frost Resistance — Hydrangea macrophylla
Hydrangea macrophylla (Thunb.) Ser.
The ability of a plant to survive and preserve generative buds at sub-zero temperatures, which is critical for flowering in temperate climates.
In the reference 162 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
For Hydrangea macrophylla, frost resistance is a key indicator, with original forms withstanding temperature drops down to –18°C. Modern breeding forms demonstrate increased resistance in the range of –20°C to –25°C, with some specimens capable of withstanding up to –30°C for shoot wood.
The main feature of the assessment is the survival of generative buds, which are significantly more sensitive to frost than the shoots themselves. Bud death leads to a lack of flowering; therefore, spring recurring frosts after the start of sap flow and temperature fluctuations that provoke premature vegetation pose a particular danger.
Cultivation technology involves focusing on remontant varieties capable of flowering on both last year's and current year's shoots. This allows the plant to maintain its ornamental value even in the event of partial freezing of the above-ground part during severe winters.
