Thanks!
Dodge-These are found mainly in the Southeastern US, and they range from Texas, to Florida, up to Newfoundland, and then all the way West to Fort Nelson, British Columbia!
There is a population of purple pitcher plant (Sarracenia purpurea ssp. purpurea) that grows naturally in Pennsylvania! Are they tropical? At best, some are semi-tropical.
All Sarracenia pitcher plant species grow well outdoors in full sun all year round here in our Mediterranean climate in California. They require a cold dormancy during the winter, and produce new leaves and
flowers in the
spring time.
Many can tolerate extreme freezes as they are found naturally in Michigan, New York, Ohio, Ontario, etc.
