Sarracenia purpurea ssp. purpurea and S. purpurea ssp. purpurea f. heterophylla require at least 5 months dormancy and all the others 3. Providing a longer period of dormancy is not harmful, but on the contrary is beneficial. Ideally Pitcher Plants should be provided with a dormant period that is of a length that will allow them to grow during the spring and summer and rest during the fall and winter. Many of the species will start to produce flower buds when their internal rest period is over, a fact we observe every year when plants in cold storage at 38°F (3.3°C) start growing flower stalks.
