Venus flytraps (Dionaea muscipula) are fascinating carnivorous plants, captivating enthusiasts with their unique trapping mechanisms. While there’s only one species, numerous cultivars exhibit diverse traits, especially in size. When considering “How Big Do Venus Fly Traps Get,” it’s essential to understand both the typical dimensions and the impressive exceptions.
The standard Venus flytrap typically reaches about 4 to 5 inches (10-12cm) in diameter at maturity. This measurement encompasses the entire plant, from the tip of one leaf to another. However, when focusing on the iconic traps themselves, they are generally smaller, measuring approximately 0.8 to 1.2 inches (2-3cm) in length. These trap sizes are perfectly suited for catching their primary prey: small insects and spiders.
But the world of Venus flytraps is full of surprises. The notion of a “typical” size gets redefined when we delve into record-breaking specimens and specially cultivated varieties.
Unveiling the Largest Venus Fly Trap Ever Recorded
For those wondering about the absolute maximum size a Venus flytrap can achieve, look no further than the remarkable plant cultivated by Jeremiah Harris, a renowned carnivorous plant expert in Colorado. His ‘Alien’ cultivar reached a staggering trap size of 2.4 inches (6.1 centimeters), setting a world record. This ‘Alien’ cultivar is distinguished by its elongated traps and short teeth, features that indeed evoke the imagery of the creature from the famous Ridley Scott film. This example demonstrates that under optimal conditions and with specific genetics, Venus flytrap size can significantly exceed the norm.
Exploring Giant Venus Flytrap Cultivars
Beyond record-holders, several Venus flytrap cultivars are specifically bred for their larger size, offering enthusiasts the chance to grow impressively big plants. These giant cultivars are highly sought after for their vigorous growth and substantial traps. Here are a few notable examples:
- B52: Perhaps the most famous giant cultivar, B52 is known for its consistently large traps and robust growth. Bred by Henning von Schmeling from ‘Carolina Giant’ seedlings, it’s named after the American B-52 bomber, reflecting its impressive stature.
- Slack’s Giant (G16): Developed by the legendary UK grower Adrian Slack, this cultivar not only boasts large traps but also exhibits striking red coloration and an upright growth habit. ‘Slack’s Giant’, also known as G16, is a reliable and vigorous grower.
- South West Giant: Originating from the UK’s Little Shop of Horrors nursery, ‘South West Giant’ distinguishes itself with exceptionally long petioles (leaf stalks). These elongated petioles elevate the traps high above the soil, creating a unique and visually striking plant. This cultivar is also known for its hardiness.
- DCXL: A relatively newer American cultivar, DCXL rivals the best in terms of sheer size. ‘DCXL’ is admired for its large trap size, attractive appearance, and robust constitution, making it a favorite among growers.
These cultivars exemplify how selective breeding has expanded the size potential of Venus flytraps, offering options for those aiming to cultivate truly giant specimens. Reputable nurseries like Hampshire Carnivorous Plants in the UK and California Carnivores in the US are excellent sources for acquiring these impressive cultivars.

Venus Flytrap Size and Prey Selection
While cultivating giant Venus flytraps is fascinating, it’s important to consider the relationship between trap size and prey. Larger traps don’t necessarily equate to capturing larger prey. Venus flytraps are most effective at digesting prey that allows the trap to fully seal. Ideally, the insect should be about one-third the size of the trap. This ensures a tight seal, crucial for digestion. Therefore, despite their potential size, Venus flytraps primarily thrive on a diet of appropriately sized insects like flies, spiders, and similar crawling bugs.
Beyond Venus Flytraps: Exploring Truly Giant Carnivorous Plants
If you’re intrigued by carnivorous plants that capture significantly larger prey, consider exploring tropical pitcher plants (Nepenthes). These remarkable plants from Southeast Asia are known to trap and digest small mammals like mice. Nepenthes species feature pitcher-shaped leaves filled with digestive fluid. Prey often slips on the pitcher’s rim, falls into the fluid, and is slowly digested.
Nepenthes truncata x ephippiata stands out as one of the largest carnivorous plants globally. This hybrid produces massive pitchers exceeding 12 inches (30cm) in height and is known to capture mice regularly. Other giants in the Nepenthes world include Nepenthes rajah, Nepenthes edwardsiana, and Nepenthes attenboroughii, each exhibiting impressive size and trapping capabilities.

Numerous online resources and videos offer further insights into these captivating carnivorous plants.
In conclusion, while typical Venus flytraps reach a modest size, the existence of record-breaking specimens and giant cultivars demonstrates their impressive size potential. When considering “how big do Venus fly traps get,” remember that both typical sizes and exceptional variations contribute to the allure of these carnivorous wonders. And for those fascinated by truly large carnivorous plants, the world of Nepenthes offers even more impressive dimensions.
