It’s common knowledge that most domesticated plants are edible and safe for human consumption. But there’s also the other side of the coin.
I’m talking about the wild plants that humans can safely consume. Does any plant come to mind? Because right now, I’m beginning to think about the Venus Fly Trap.
As the name suggests, it traps and consumes flies but is it edible itself? I guess your next line of thought is; the Venus Fly Trap is poisonous, and that’s why it consumes insects.
It’s one of the few known carnivorous plants that inhabit the Earth. But we just discovered the contrary.
Human beings could also eat these wonderful plants. Yeah, I know vegetarians must be tearing their hairs out, but they shouldn’t.
In this article, we dig deeper into more facts about the Venus Fly Traps and also determine whether it’s a safe meal for your consumption.

More About Venus Fly Trap (Dionaea muscipula)
Any discussion on insectivorous plants consuming bugs and insects won’t be complete without mentioning the Venus Fly Trap. Darwin, the great geologist, recognized the Venus Fly Trap as “One of the most wonderful [plants] in the world.”
What caused Darwin to be so captivated by the plant? The answer lies in the main characteristic of the Venus Fly Trap— the ability of its jaws to snap around an insect.
It’s a small plant with four to seven leaves on a stem. Each plant has about six stems.
The plant grows to about 5 inches in diameter. The edges of the leaves have what plant scientists describe as “teeth.”
These leaves form a trap when they snap into a concave shape. The leaf blade of the venus fly trap has two regions; one is heart-shaped and carries out photosynthesis, while the other is a terminal lobe hinged at the middle, which forms a trap. This is the true leaf.
The terminal lobes’ inner surface contains a red pigment with edges that secrete mucilage. These inner surfaces have what we call stiff hairs.

The Trapping Mechanism
If an insect happens to cross over these hairs, they trigger calcium ions that ultimately lead to the hinges shutting and trapping the insect. At this stage, the insect is trapped but not dead yet.
As expected, the insect will keep struggling to get out of the trap. The continuous struggle keeps knocking the trigger hairs further, which send out electrical impulses once per minute.
When the hairs release triple impulses, the calcium ion levels are raised, causing a release of the hormone jasmonate. Jasmonate is the hormone that catalyzes the gland cells in the venus fly trap to release digestive enzymes.
After a few days of digesting the insect, the Venus flytrap will open up its lobes again to get the next meal. We know your next big worry is whether the venus fly trap could be harmful to humans or not.

Well, the fact is, they don’t bite even if you insert your finger inside the hinged leaves (don’t yell at me if you try, and they do). The Venus flytrap can only snap shut and produce digestive juices when it’s sure it has caught something tangible that’s worth a meal.
It can determine whether the trigger is caused by a false object or a real meal; it should be able to close when a couple of stiff hairs are touched within the first 20 seconds of the first alarm.
And that can’t be your finger. On the contrary, you could do more damage to the plant than the other way round.
Unfortunately for you, getting a taste of these wonderful plants will be a tall order as they are rarely found around. They mainly inhabit the wild areas in specific locations.
They are a native of South and North Carolina in the United States, and you will find them growing in only two regions, namely the sandhills and the coastal plain.
Soils in their natural habitats are nutrient deficient though they benefit mostly from enough sunlight and humidity in their environment. Despite the nutrient deficiency soils they grow in, the Venus fly trap can survive because of its trapping mechanisms.
These do not necessarily guarantee survival, but they benefit from consuming a bug or two often. You will be lucky to encounter these plants since they are so scarce.
Further, they are an endangered species, which could make your intention to turn them into a meal a legal issue.

Venus Fly Traps reproduce through seeds when their flowers become pollinated. Their seeds mature in 5 – 6 weeks, morphing into a black pear shape.
Birds, wind, and other agents transport these seeds into new areas, making them inhabit newer regions. Another interesting bit about the venus flytrap is that they can reproduce asexually.
Their roots grow into the soil, forming bulb roots. You could get another fly trap from this bulb.
Can Humans EAT Venus Fly Traps?
As you may be aware by now, most carnivorous plant species like the venus fly trap are rare and endangered. They grow in soils that lack nutrients hence depend on trapping and feeding on insects to supplement their nutrient needs.
In the case of the Venus flytrap, many factors have affected or interfered with its natural habitat. This includes urbanization, poaching, and environmental changes.
Such challenges may make the consumption of the plant difficult; however, if your worry is more from a health point of view, no need to cast aspersions. They are safe to eat.
However, there are enough other beneficial plants to eat out there, so we would recommend looking elsewhere.
Growing the Venus Fly Trap

Gardeners can plant seeds of the venus fly trap both indoors and outdoors. The best season to grow them is around spring, when they start growing rapidly, ending with a subsequent dormant phase.
Growing the venus fly traps calls for lots of patience. It takes 3-4 years to develop a new plant from seed to full maturity.
You can quicken their growth rate by ensuring optimum conditions.

If you intend to establish your venus fly traps through seed germination, there are few factors you should put into consideration: germination time and the seed age.
You want to grow your seeds before they become older. The probability of venus fly traps producing seedlings lowers with age.
Some conditions to put in place for successful seed germination of your flytrap are:
- A well-draining container; the pot should have drainage holes. This helps prevent your roots from rotting.
The pot should be tall to accommodate the long taproots of the Venus flytrap. Depending on your preference, you can pot them individually in small pots or large pots as bundles.
You want to be keen on the material your pot is made of. Avoid clay, terracotta, and ceramic materials at all costs; they leach minerals to the ground.
Another container you want to avoid using is the terrarium. They are harmful to venus fly traps since they block sunlight, restrict air movement, cause rotting issues and prevent the flytrap from capturing bugs.
Terrariums help with humidity, but you can achieve this through misting.

Plant your seeds in carnivorous plant soil. Source the soil type from commercial stores that sell soil for carnivorous plants. You can also find resources online on how to prepare your carnivorous plant soil.
They love potting media that is free of fertilizer.
Only use pure water sources to water your venus fly trap soil. Ideally, this should be distilled water, reverse osmosis water, or rainwater.
Tap or bottled water has too many minerals that could kill your precious plant.
Watering should only be enough to wet the soil but not flood it. You can check this with your finger to ensure the ground is neither too hard nor overwatered.
Other Things To Lookout
- Your soil media should be humid all through the germination period.
- Sprinkle the seeds on top of the soil to avoid burying them.
- Wrap your container or pot inside a transparent material, preferably a Ziploc bag.
- Ensure to put the seeds under direct sunlight for at least six hours a day. Venus flytraps love sunny spots.
- Mist the seeds to increase humidity.
- Your seeds should germinate in five weeks.
If growing indoors, you may want to supplement lighting with fluorescent lights of 6500K colors or LED.
- Feed the venus fly trap once a month by introducing house flies if growing them indoors. You can also place the plant outdoors to allow them to capture insects on their own.
- The plant doesn’t survive on bugs, but they are necessary to encourage growth.
Artificial Propagation Germination
Gardeners can also propagate venus fly traps through leaf cuttings. This entails producing a clone by extracting a leaf from the parent plant.
For an effective result, get the plant part during the active growing stage and not during dormancy. Below is a quick step-by-step guide.
- Uproot Venus flytraps from its growing medium and empty the soil until all the roots are bare.
- Scout for a healthy leaf amongst the external leaf layers.
- Pluck out the healthy leaf gently and firmly pull it downwards and outwards to ensure the leaf gets detached with some rhizomes at its base. You should grab the leaf from the top.
- You can repeat the above step as many times as you desire.
- Next, transfer the leaf cuttings to a carnivorous plant soil medium and lay them on their side. The soil should be moist.
- Cover the rhizomes with soil and wait for the seedlings to sprout.
The seedlings should start growing from the leaf pullings in 1-3 months. Afterward, await maturity in 2-3 months.
Things To Avoid
What you want to avoid during germination is causing unwanted stress to the plant. You can cause this by triggering the plant to snap unnecessarily.
The leaves of the Venus flytrap are only supposed to close during feeding time. Regular touching of the plant weakens its leaves, eventually leading to leaf loss.
If planting them indoors, place them in a still place with no movements in the environment.
If on a window sill, the curtains should be away from the plant to avoid causing unwanted triggers by passing through the leaves. Also, place them in areas with no kids or pets.
Dormancy is Essential
Venus flytraps will thrive through consistent watering, enough sunlight condition or light exposure, availability of bugs or insects, and ensuring a recurring dormancy every year.
Dormancy is vital for venus fly traps. They start dying if they skip dormancy for several years in a row. Achieve dormancy by exposing your venus fly trap to low temperatures of 7 degrees celsius.
Your venus fly trap should maintain a complete dormancy period of at least three months.
If you live in an area where lower temperatures are not the usual norm, consider using a refrigerator to achieve dormancy.
Please don’t bother about fertilizers since they majorly rely on lighting and feeding for their fast growth.
The Venus flytrap is one of the most amazing wonders of nature out there, thanks to its ability to consume insects by trapping and digesting them.
It’s an endangered species and must be protected from the ill effects of humans on its natural habitat.
If you had doubts about whether the plant is edible, you can put them to rest.
