Pitcher Plants in Winter

3-19-13 pitcher plant in winter2 IMG_6845The pitcher plant flowers that bloomed in bogs last June persist through the winter. Their maroon petals are gone, as is their scent, and they are withered and somewhat drab-colored, but the upside down flowers are still on display, supported by long, graceful stems protruding above the surface of the snow. Pitcher plants flower for about two weeks at the beginning of summer, during which time their pollen is distributed (primarily by bees). After fertilization, 300 – 600 seeds form within each ovary. This is when the carnivorous pitcher leaves develop. In late fall, the “pitchers” begin to wither and the seed pods turn brown and split open, scattering seeds. In three to five years, the plants which these seeds grew into will begin flowering.
