Pitcher Plants Flowering

6-17-16  pitcher plant flower parts labeled 298Pitcher plants are known for their unique, insect-trapping leaves, but their flowers are just as unusual.  Their petals are a deep burgundy color and attract pollinating flies by looking like raw meat. The sepals, usually green structures that protect the bud and then become inconspicuous when the flower opens, are leathery and remain long after the petals fall off, well into winter.  The pistil, or female part of the flower, has a typical ovary at its base, where seeds are formed, but the style (stalk-like in most flowers) expands into a large, star-shaped umbrella. This umbrella becomes the lowest part of the flower as it droops downward in its early open stages and collects pollen that falls off of the anthers surrounding the ovary. The stigmas, where pollen must land in order for pollination to take place, are located on the five points of the star-shaped style, where visiting insects land.  A pitcher plant is designed to be pollinated by pollen stuck to the body of the insect before the insect descends onto the lower platform section of the style, where it crawls around gathering nectar, and inadvertently, pollen.
