Sarracenia

Source: Gardening Studio
Like nepenthes, sarracenia are pitcher plants, though they are primarily found in parts of the United States and Canada. Unlike many other carnivorous plants, sarracenia look similar to normal flower species. For this reason, North American pitchers often fool their prey (and people).

Near the end of summer, the sarracenia’s leaves turn a deep reddish-purple hue to attract flies. Once a fly enters the tall, hollow leaf, it quickly encounters a pool of water and is trapped. The pitcher’s steep sides and the wetting agent it secretes prevent any chance of escape. Like other carnivorous pitcher plants, the sarracenia acts as a host to numerous other organisms.
