Henry's lily has the ability to adapt to a wide range of temperature conditions, but its distribution may still be limited by different combinations of water and heat conditions. It thrives best in warm climates during the summer with adequate rainfall or watering. Prolonged periods of cloudy and rainy weather, as well as prolonged high temperatures, can increase the likelihood of Henry's lily dying. In winter, proper protection against cold can improve the plant's survival rate.
Regional wintering strategies
Henry's 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.
