Frost resistance — Lavandula angustifolia

Lavandula angustifolia Mill.

An adaptive trait of Lavandula angustifolia Mill. to sub-zero temperatures, determining plant survival in temperate climates and a critical freezing threshold of -25°C.

In the reference 8 varieties crop English lavender, where this is mentioned in the description.

The frost resistance of English lavender is assessed using laboratory freezing methods in the range from -16°C to -25°C with an analysis of damage to the bark, cambium, xylem, and pith. At -16°C, tissue damage is minimal; at -18°C…-20°C, the first signs of injury are observed, while the -25°C level acts as a critical threshold leading to the freezing of the above-ground part.

Annual shoots are most vulnerable to cold exposure, whereas two- and three-year-old bush structures responsible for regeneration possess significantly higher resistance. In the absence of snow cover at temperatures below -30°C, the risk of plant death increases substantially, necessitating the consideration of varietal differences and the assessment of crop status during the growing season.
