any pollen they are carrying on the stigmata as they enter. The pollinators generally exit the flower, having been dusted with the plant's own pollen, by lifting a petal. This one-way system helps to ensure cross pollination. In late summer and autumn, the plant stops producing carnivorous leaves, and instead produces flat, non-carnivorous phyllodia. This is probably an adaptation to low light levels and insect scarcity during the winter months, and shows clearly the cost of carnivory. The yellow pitcher plant is easy to cultivate, and is one of the most popular carnivorous plants in horticulture. The yellow pitcher plant readily hybridises with other members of the genus Sarracenia: the hybrids S. x catesbaei (S. flava × S. purpurea) and S. moorei (S. flava × S. leucophylla) are found in the wild, and are also popular amongst collectors.
