Meet the captivating Venus Fly Trap (Dionaea muscipula), a fascinating carnivorous plant that has bewitched botany enthusiasts for centuries.

Hailing from the wetlands of North and South Carolina, this striking perennial boasts distinct lobes with jaw-like traps that lure and devour unsuspecting insects. Its unique appearance has earned it the moniker “nature’s little predator.” Though maintaining its carnivorous allure might seem daunting, the Venus Fly Trap thrives in moist, acidic soil, and with a little care, it will reward you with its incredible spectacle of snapping traps and delicate beauty.

Most common Venus Fly Trap varieties:

  • ‘Big Mouth’: Prepare to be amused by the wide-open jaws of this plant, making it a true spectacle for any plant enthusiast.
  • ‘Red Dragon’: Feel the mythical vibes of this majestic plant, with its fiery red allure and an aura of ancient legends.
  • Sawtooth’: Unleash your curiosity as you encounter the captivating saw-like edges of this plant’s traps, ready to ensnare unsuspecting prey.
  • ‘Bohemian Garnet’: A crimson jewel among plants, this stunning beauty flaunts deep red hues that evoke the spirit of Bohemian allure.
  • ‘Fused Tooth’: Nature’s fusion artist, this plant showcases tooth-shaped traps that merge functionality with artistic charm.
  • ‘Wacky Traps’: Step into a world of whimsy and surprise with this unique variety, where each trap seems to have a playful personality of its own.


Growing Venus fly traps as potted houseplants is a great way to observe their fascinating behavior up close. Despite being carnivorous, they are relatively easy to care for.

  • Soil: To replicate their natural surroundings, it’s best to utilize a potting mix that is peat-based and has excellent drainage. This will imitate the damp, acidic, and nutrient-sparse soil found in their native habitats.
  • Water: To water the Venus fly trap, it’s better to use rainwater instead of tap water. You can set up a rain barrel or collect rainwater in a container outdoors for this purpose. If rainwater is not available, distilled water is a good substitute.
  • Light: During the growing season, it is important to give your plant 12 hours of light each day, with at least 4 hours of bright and direct sunlight.
  • Feeding: Feed it live insects like flies and mosquitoes. Use tweezers to gently place the insects inside the trap. It’s also a good idea to keep a feeding journal, as the plant has a limited number of trap openings and closings during its lifetime. It is crucial to avoid triggering traps for amusement, as shutting them down consumes a significant amount of energy from the plant.


Propagating Venus fly traps is a breeze through division, the most reliable method.

  1. In early spring, mature plants produce offshoots which can be carefully removed with a sharp knife or pruners, ensuring they have roots attached.
  2. Prepare pots with fresh peat-based growing medium, making holes in the center of each pot. Plant the offshoots in these holes, water them thoroughly, and maintain evenly moist soil.
  3. Find a spot with indirect light for the pot, avoiding bright sunlight until the newly propagated plant begins to develop its roots. With these simple steps, you can effortlessly multiply your Venus fly trap and enjoy more of these captivating carnivorous wonders!


To maintain the Venus fly trap’s carnivorous display, it’s best to prevent it from flowering during May or June. This is because the flowering process can draw a lot of energy from the plant.

Frequently Asked Questions

How hard is it to keep a Venus flytrap alive?

Keeping a Venus flytrap alive is not exceptionally difficult, but it does require some specific care and attention. These plants have unique needs due to their carnivorous nature and their native environment. If you can provide the right conditions, they can thrive and live for many years.

The key factors to consider for successfully keeping a Venus flytrap alive are:

  • Light: Venus flytraps require plenty of bright, direct sunlight. They should receive around 12 hours of light daily during the growing season (spring to fall).
  • Soil: These plants prefer nutrient-poor, acidic soil. Using a peat-based potting mix with good drainage will mimic their natural bog environment.
  • Water: Venus flytraps must have consistently moist soil at all times. Using distilled or rainwater is recommended, as tap water may contain minerals that can harm the plant.
  • Feeding: They obtain nutrients by capturing and digesting small insects. While you can feed them, it’s not always necessary, as they can catch insects on their own.
  • Dormancy: Venus flytraps go through a dormant period during the winter months. During this time, they require cooler temperatures and reduced watering.

If you can meet these requirements and provide proper care, your Venus flytrap should flourish. It’s important to research and understand their needs thoroughly to ensure their long-term health and survival.

What can a Venus flytrap eat?

Venus flytraps are carnivorous plants and primarily feed on small insects and arachnids. They can catch and eat:

  1. Flies (such as house flies, fruit flies)
  2. Mosquitoes
  3. Gnats
  4. Spiders (small ones that venture into the traps)
  5. Ants (occasionally, if they are small enough)

The traps of a Venus flytrap are triggered by the movement of their sensitive trigger hairs. When an insect or arachnid touches the trigger hairs multiple times within a specific time frame, the trap snaps shut, capturing the prey inside. The trap then secretes digestive enzymes to break down the captured prey and absorb nutrients from it.

It’s important to note that Venus flytraps do not rely solely on capturing prey for their nutritional needs. They can photosynthesize like other plants, but their carnivorous adaptation allows them to thrive in nutrient-poor environments where they may not get enough nutrients solely from the soil. As fascinating as their carnivorous behavior is, it’s essential to provide the right conditions for their overall care and well-being.

How many times can a Venus flytrap eat before it dies?

This plant’s mouths can close up to four or five times before it perishes.

How many years can a Venus flytrap live?

If taken care of properly, these plants have the ability to live for an extended period of time. On average, a Venus Flytrap can live for up to 20 years.

Why did my Venus flytrap turn black after eating?

If your Venus flytrap turned black after eating, it is likely a natural and normal part of the plant’s digestive process. When a Venus flytrap captures and consumes its prey, it triggers a series of physiological changes to digest and absorb nutrients from the captured insect or arachnid.

After the trap closes around the prey, it secretes digestive enzymes to break down the soft tissues of the insect, converting it into a nutrient-rich slurry that the plant can absorb. This process can take several days to a couple of weeks, depending on the size of the prey and environmental conditions.

During digestion, the trap’s outer surface may darken or turn black, which is an indication that the enzymes are at work breaking down the captured prey. This darkening is generally temporary, and once the digestion process is complete, the trap will reopen and reveal the indigestible parts of the prey, such as exoskeletons.

It is important to differentiate between the natural darkening that occurs during digestion and other possible causes of blackening, like fungal infections, overfeeding, or improper care. To keep your Venus flytrap healthy, it is crucial to maintain the correct environmental conditions, such as providing enough light, moisture, and soil. If you observe any additional indications of stress or extended darkening, it may be necessary to investigate further and take appropriate measures to ensure the plant’s health.
