Sarracenia purpurea is a fantastically strange carnivorous plant that is easy it grow. Mature plants produce 15-20cm pitchers that grow horizontal in a rosette pattern, the pitchers curve upwards and wider toward the pitcher mouth. The colours range from bright yellow-green to deep purple with many red veins running throughout the pitchers. Sarracenia purpurea ssp. purpurea is the hardiest of all pitcher plants & can tolerate temperatures as low as -34 degrees Celsius. The purple pitcher makes a great outdoor container plant; they do best when placed in bright sunlight. Sarracenia are one of the most efficient of all carnivorous plants, consuming vast numbers of insects. They lure prey by secreting nectar around the lip of the pitcher; the nectar paralyses the insect and it falls into the tube. Once the insect reaches the bottom it is slowly dissolved and the plant absorbs the nutrient value.
