Lily Frost Hardiness

Lilium L.

This trait is determined by a lily's membership in a specific hybrid group and the ability of the bulb to overwinter in designated climatic zones.

In the reference 106 varieties crop Lily, where this is mentioned in the description.

The frost hardiness of lilies is assessed based on their taxonomic classification, where Asiatic and LA hybrids are considered the most resilient, while Longiflorum and Candidum groups require specific conditions or covering. The hardiness of wild species, such as the tiger lily, is attributed to the function of LlR3MYB proteins, which activate the synthesis of protective flavonoids like quercetin and kaempferol upon cooling.

Cultivation technology directly depends on this indicator: varieties with low frost hardiness require air-dry cover to protect against freezing and moisture. An important aspect is bulb maturation at the end of the growing season, which is influenced by potassium and phosphorus fertilizers, as well as the ability of seedlings to withstand spring recurrent frosts, which are often more dangerous to the crop than low temperatures during the dormancy period.
