Carnivorous Plants

Fascinating gardens are a true art form and if you are wanting one that will catch the attention of others, you may consider adding a few of the best carnivorous plants available. There are several interesting exotic species to consider, such as the ever popular Venus Flytrap or the Cobra plant. Both these plants consume insects and can be of benefit to any garden in that way and in addition, they are a great conversational piece. While the benefit is strictly related to the size and type of carnivorous plants that you own, these plants can provide a small level of relief while providing entertainment to adults and children alike.

Basically there are five different types of carnivorous plants for you to consider. The most common type, is the Venus Flytrap found in cultivated varieties of the Dionaea muscipula family. Snap traps rely on a mouth that close in around its pray, where the plant will eat whatever it catches.

Once an insect is captured, the plant closes its trap tightly around the meal and bathes it in digestive juices that dissolve the insect’s soft, inner parts. Digestion takes five to 12 days, after which the trap reopens, then the insect’s exoskeleton blows away in the wind or is washed away by rain.

These plants range from colorful to bland, and do not have moving parts like their snap trap counterparts.

Sundew plants of the Venus Flytrap family are amongst the most interesting to watch. These plants secrete a glue which traps and breaks down insects for nourishment. The type of secretion created by this particular plant can cause skin irritation to humans and therefore should be treated with caution.

Bladder traps plants are a fascinating subset of carnivorous plants. Numerous, tiny glands inside the bladder absorb most of the internal water and expel it on the outside, and as a result, a partial vacuum is produced inside the bladder and the pressure on the outside becomes greater than the inside. This causes the walls to squeeze inward and explains their slightly concave appearance. Bladderworts are more commonly found underwater than above ground, which is another distinct characteristic from other carnivorous plants.

Finally, the lobster pot traps are among some of the most unusual looking carnivorous plants that you can acquire, they function by giving insects an easy way to enter, but little chance of escape.

Corkscrew plants are interesting, in that, the inside of the plant mouth is filled with downward pointing obstructions, used to prevent it’s prey from escaping it’s grasp.

For those interested in borderline species, there are several varieties of plants that do not meet all of the requirements of carnivorous plants, but have sharing characteristics. Some of these type of plants come from the Martyniaceae family, such as the Brocchinia Roridula. These plants lack one of the three required aspects, which is to attract, kill and digest prey, to be classified as a true carnivorous plant.

Carnivorous plants should be placed where young children and babies cannot reach them. While most of them are relatively harmless to humans, digestion of these plants should be avoided, due to the digestive enzymes that the plant utilizes to break down prey.
