Regional wintering strategies
Florida swamp-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 -30°C, 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.

Symptoms of Low Temperature in Florida swamp-lily
Florida swamp-lily is cold-tolerant and thrives best when the temperature is above 5°C. During winter, it should be kept above -25°C. When the temperature falls below -30°C, although there may not be any noticeable changes during winter, there may be a decrease in sprouting or even no sprouting during springtime.
Solutions for Low Temperature in Florida swamp-lily
In spring, remove any parts that have failed to sprout.
Symptoms of High Temperature in Florida swamp-lily
During summer, Florida swamp-lily should be kept below 35°C. When the temperature exceeds 38°C, the leaves of the plant may become lighter in color, prone to curling, susceptible to sunburn, and in severe cases, the entire plant may wilt and become dry.
