Pyrenean lily is native to a temperate environment and has a preference for temperatures ranging between 32 to 100°F (0 to 38℃). It can adapt to changes in temperature throughout the seasons, however, maintaining the appropriate temperature range is crucial for its growth.
Pyrenean lily has strong cold resistance, so special frost protection measures are usually not necessary during winter. However, if the winter temperatures are expected to drop below {Limit_growth_temperature}, it is still important to provide cold protection. This can be achieved by covering the plant with materials such as soil or straw. Before the first freeze in autumn, it is recommended to water the plant abundantly, ensuring the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
