Variety traits

Frost resistance of Cordyline

Cordyline Comm. ex Juss.

The ability of species within the genus Cordyline to tolerate sub-zero temperatures, which determines their suitability for outdoor cultivation. Hardiness levels vary from tropical species that perish at +7...+12°C to New Zealand forms capable of regenerating after -10°C.

In the reference 8 varieties crop Palm lily, where this is mentioned in the description.

The frost resistance of Cordyline is evaluated based on temperature thresholds and USDA zones, where hardiness is often determined not by the preservation of the aerial parts, but by the plant's ability to regenerate from underground rhizomes. Tropical species, such as Cordyline fruticosa, are extremely sensitive to temperature drops and require conditions above +7...+12°C.

Species of New Zealand origin, such as Cordyline australis, are the most frost-resistant and can withstand brief frosts down to -7...-10°C. In regions with climates colder than USDA zone 8a, a key survival factor is not only temperature but also soil moisture, as waterlogging during the winter period induces rhizome death and the development of rot.
