Facts on Carnivorous Plants


Carnivorous plants attract, capture and kill their prey. They eat the prey by producing digestive enzymes or rely on bacteria to perform the digestion process. They also absorb the nutrients from the prey to get an extra boost of energy and growth.


Of the 250,000 to 400,000 flowering plant species, only about 200 are carnivorous.


Carnivorous plants are divided into two groups: One type has active traps triggered by movement and the other has passive traps.

Food Sources

These plants eat insects and small animals such as mites, flies, spiders and frogs, but do not survive on just insect and animal protein. They are green plants full of chlorophyll and produce food through photosynthesis. They only supplement their nutrition with prey.


Carnivorous plants are natural bog plants. They live in an area of constant moisture, high humidity, bright light, poor soil and plenty of insects.


Venus fly traps, pitcher plants and sundews make good houseplants if you grow them in a plant terrarium. Feed the plants insects once or twice a month or lightly fertilize every four weeks.
