Pitcher plants are not poisonous to humans or pets. Also, contact with Pitcher plants is completely harmless. These plants make up safe and beautiful houseplants. This article will give you an overview on how Pitcher plants can make up great houseplants. Also, it will give you pointers to avoid harming Pitcher plants. Pitcher plants are unable to poison humans not only if they accidentally come in contact with either their digestive fluid or any other part of the plant; pitcher plants are also non-toxic to such a degree that they are being eaten in some parts of the world.
As you can see, you are more likely to eat a nepenthes than it is likely for them to eat you! While your children should not attempt to eat up a whole pitcher plant, they are harmless to the touch and even way safer than other popular house plants. Nepenthes pose no threat to the curious fingers of exploring toddlers.
As all pet owners know, it is close to impossible to hinder either cats or dogs from putting things in their mouths. They like nibbling at and licking everything they can get to, be it actual food, furniture, or houseplants. In the latter case, a carnivorous and exotic plant might give the impression that it poses a risk. Especially cats are known to be attracted to plants because they enjoy their fibrous texture that, when it is consumed in small amounts, or when it comes in the form of special plants like kitty grass, can aid their digestion.
Digesting a few bites of a Nepenthes might result in mild digestive issues in cats but usually does not lead to the display of any serious, long-lasting effects.
In the case that your pet has consumed large quantities of such a plant, though, there are nevertheless some symptoms that you should keep an eye out for: if you notice your cat vomiting a lot, suffering from diarrhea, being unusually lethargic, or displaying a rash or any other kind of irritation around their mouth you should contact a vet.
When you need to visit a veterinarian because of symptoms like these, it makes a lot of sense when you take a piece of your pitcher plant with you, so that they know what they are dealing with and can assess the situation quickly and competently. In general, it will be more important to save the plant from your pet and not the other way round. There are some things you can do to avoid your house plants ending up chewed up or shredded. Some plants even defend themselves by their taste.
Venus flytraps, another well-loved carnivorous plant, for example, are known to taste sour and thus not to be to the liking of cats. To protect plants with a more delicious taste from maltreatment by a cat, you can make sure that your cat always has some kitty grass or catnip to keep them busy. Aside from that, you should try to put your nepenthes in locations that the cat cannot reach.
While cats might be likely to crawl up shelves and jump onto whatever when it comes to dogs it is often enough to simply put your plant somewhere up high. A hanging planter is a good idea in both cases.
Just make sure to put it somewhere in the room where the cat cannot jump to from other high locations. Back in the 19th century, the European adventurers and explorers traveling the world brought back home stories of cruel, man-eating plants that lurk in exotic rain forests. Nowadays we know that this is not true. Now we know that nepenthes do not grow remotely tall enough to ingest a human being. Nevertheless, this shows that pitcher plants have fascinated and scared human beings for a long time.
Especially the most well-known of them, which are the species that belong to the genus called nepenthes, drew botanists as well as laypeople in by being both scary and undeniably beautiful. Both intrigued and somehow a little fearful we still like to observe the insects that fall into the trap of a pitcher plant.
But, are these carnivorous plants poisonous unsafe to be kept as house plants? And a few of these pre-carnivores evolved the ability to trap insects, digest their exoskeletons, and absorb nutrients from their carcasses. Those plants survived better in places with poor soil quality because they could get carbon and nitrogen and other nutrients from insects.
It was a desperate measure. For a plant, turning leaves into specialized traps means sacrificing a lot of energy. All of these evolutionary adaptations make for pretty finicky house plants. Since carnivorous plants evolved to live in nutrient-poor soil, the minerals in most tap water overwhelm the roots.

The nitrite and nitrate ions made available by the bacteria are readily absorbed by the roots of plants. If the nitrification process is impaired, there could actually be a shortage of these nitrite and nitrate ions; hence, the carnivorous plants have evolved a mechanism to obtain a supplemental supply of nitrogen. A Venus' flytrap Dionaea muscipula. Active traps are formed by hinged, 2-lobed leaf blades fringed with stiff hairs. When the leaf blade folds closed, it traps an insect within a jail of interlocking hairs.
Recent studies indicate that the pressure loss may be in the layer of mesophyll cells underlying the upper epidermis. When these cells suddenly become flaccid, the leaf folds upward along the midrib. A decrease in ATP adenosine triphoshate is associated with each closure, suggesting that biochemical energy is also involved. Repeated stimulation of the trap by touching the trigger hairs too frequently will noticeably fatigue the trap. This fly is trapped between the folded halves of a Venus' fly trap leaf blade.
The fly is imprisoned within a jail of interlocking hairs along the leaf margin. This fly later escaped, only to be caught and digested by another leaf. Bladderworts T he only carnivorous plant with a true "trapdoor" is the remarkable bladderwort Utricularia. This little submersed aquatic plant has one of nature's most precise and delicate traps, and certainly the most rapid.
Thousands of minute bladders are attached to feathery submersed branchlets by tiny stalks. Some authorities consider these finely divided branchlets to be modified leaves. The flattened, pear-shaped bladders range in diameter from 2 millimeters the size of a pinhead to about 4 millimeters the size of a BB. At one end is an opening and a flap of tissue which forms the door. The door hangs down from the top of the entrance like a garage door, except it opens inward.
Support tissue and a mucilage coating around the door frame helps to seal the door and prevent water from entering the bladder. The door opening is surrounded by several bristly hairs that resemble the antennae of a tiny crustacean or insect. Numerous, tiny glands inside the bladder absorb most of the internal water and expel it on the outside.
As a result, a partial vacuum is produced inside the bladder and the pressure on the outside becomes greater than inside.
This causes the walls to squeeze inward and explains their slightly concave appearance. Left: A flowering bladderwort plant Utricularia vulgaris raised out of the water.

Note the bristly hairs at the entrance to the bladder traps. T he airtight door is hinged to allow easy entry; but like a door, it cannot be forced open from within.
Special trigger hairs near the lower free edge of the door cause it to open. When a minute aquatic organism touches or hits one of these extremely sensitive hairs, the hair acts as a lever, multiplying the force of impact and bending or distorting the very pliable door. This breaks the watertight seal and, since the bladder contains a partial vacuum, the hapless victim is sucked in.
Bladder extracts from some species of bladderworts indicate that enzymes secreted by the plant may be involved in the digestion process. View of the slender branchlets of a bladderwort plant Utricularia vulgaris bearing tiny, pear-shaped bladders.
One bladder trap has been enlarged to show a trapped copepod, a minute crustacean related to shrimp and crayfish. The tail, legs, and antennae of the copepod are clearly visible. The entire bladder is about 2 mm across, slightly larger than the head of an ordinary straight pin. Predatory Fungi A ny discussion of carnivorous plants would be incomplete without mentioning the amazing predatory fungi that actually capture and devour they prey. These organisms are technically not plants since they belong to the Kingdom Fungi, but they are nonetheless quite remarkable.
The predatory fungi belong to the Phylum Division Zygomycota. In some mycology books they are placed in the Class Zygomycetes. The zygomycetes include a number of microscopic fungi that attack bread, dead flies and moving animals. You have probably seen the web-like filaments and black sporangia of black bread mold, especially if you allow freshly-baked bread without preservatives to get moldy. Other references place these fungi in the Class Deuteromycetes Imperfect Fungi because their sexual cycle is not fully understood; therefore, it is difficult to place them in a definite fungal class.
The visible body of these fungi consists of a mass of intricately branched filaments, collectively referred to as a mycelium. Several predatory species in the genus Dactylaria attack minute nematodes called eelworms, and another fascinating species Dactylella tylopaga attacks microscopic amoebas in the soil.
I t is hard to imagine a filamentous fungus that actually lassos its prey, but this is the case in certain species of Dactylaria. Some of the filamentous strands of this fungus form a loop which serves as an animal trap. Minute nematodes called eelworms slither into the loop, hoping to eat the fungus.
