The showy lily primarily thrives in a temperate climate and prefers a temperature range of 41 to 95 ℉ (5 to 35 ℃). In its native growth environment, the plant can withstand temperatures as low as 23 ℉ (-5 ℃) during the winter, but it requires a warmer temperature range of 68 to 77 ℉ (20 to 25 ℃) during its growing season. In different seasons, it is suggested to adjust the temperature by providing adequate shading and ventilation to avoid overheating in summer and to protect it from frost in winter.
Showy 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.
