Most people treat the Venus flytrap like a weird, green novelty item. They buy one at a big-box hardware store, stick it on a kitchen windowsill, and watch it slowly turn into a black, shriveled mess within three weeks. It’s kinda sad, honestly. Because in reality, these plants aren’t meant to be disposable "pet" toys. They are hardy perennials. If you actually treat them like a living thing instead of a desk gadget, they can outlive your dog.
So, let's get to the point. How long does Venus fly trap live?
In the wild, a healthy plant usually hangs around for about 20 years. In a controlled greenhouse or the home of a dedicated hobbyist? Some specimens have been known to push past the 25 or even 30-year mark. But the average lifespan for a flytrap bought by a beginner? Usually about 30 days. That gap is huge, and it’s almost always because of a few simple, but fatal, misunderstandings about what this plant actually is.
The 20-Year Bog Dweller
You’ve probably heard these plants are tropical. They aren’t. They’re actually from the Carolinas—specifically a tiny 90-mile radius around Wilmington, North Carolina. It gets cold there. It frosts. It even snows sometimes.
Because they live in nutrient-poor bogs, they evolved to eat bugs to get the nitrogen they can't find in the soil. But here is the thing: a single trap on the plant isn't immortal. Each individual trap can only snap shut about 5 to 10 times before it gets tired and dies. Once a trap has "spent" its energy, it turns black. This doesn't mean the whole plant is dying. It's just a leaf retiring.

A 20-year-old Venus flytrap is basically a massive underground rhizome (sort of like a bulb) that keeps pumping out new leaves. As long as that "heart" of the plant stays healthy, the plant keeps living.
Why Most Flytraps Die Early
If they can live for two decades, why does yours look like a charcoal briquette after a month? It usually comes down to three things:
- The "Magic" Water Trap: You cannot give these plants tap water. Period. Most tap water is full of minerals like calcium and sodium. To a flytrap, that's literal poison. Their roots are built for pure rainwater. If you use tap, the minerals build up in the soil and "burn" the plant to death from the inside out.
- The Burger Problem: People love to feed them "human" food. Don't. A piece of hamburger meat or a slice of deli turkey will rot the trap because the plant can't digest fats. It needs the chitin from an insect's exoskeleton.
- Missing Their Nap: This is the big one. Since they aren't tropical, they must go dormant in the winter. They need 3–4 months of chilly temperatures (between 35°F and 50°F) to rest. If you keep them in a warm living room all year, they basically die of exhaustion after a couple of seasons. It's like a human trying to stay awake for three years straight. Eventually, the system just collapses.
Survival in the Wild vs. The Living Room
In the wild, the main thing that kills a Venus flytrap isn't old age—it's competition. They are tiny. If taller grasses grow over them and block the sun, they can't photosynthesize and they starve. Fire is actually their best friend. Periodic wildfires in the Carolinas burn away the tall brush, clearing the "floor" so the flytraps can soak up the sun.
When you bring one home, you're the "fire." You have to keep the area clear and the light high.
How to Tell if Yours is Reaching Old Age
You won't see gray hair on a plant. Instead, look at the rhizome. Experts like Peter D'Amato, author of The Savage Garden, point out that as the plant ages, the rhizome (that white, bulb-like base) will naturally split.
One plant becomes two. Two become four.

Technically, the "original" plant might be gone, but because it's a clone of itself, the organism is essentially continuing its life cycle indefinitely. If you repot and divide these clusters every few years, you could theoretically keep a lineage of the same plant going for your entire life.
The Secret to Longevity: Actionable Steps
If you want your plant to actually hit that 20-year milestone, you have to stop treating it like a houseplant. It’s a bog plant.
- Only use Distilled Water: Or rainwater. Or reverse osmosis water. Never, ever use "spring water" or tap.
- Sun is Non-Negotiable: They need at least 6 hours of direct, stinging sun. A "bright room" isn't enough. They want to be outside or under a very high-powered LED grow light.
- Peat and Perlite Only: Never use potting soil. Potting soil has fertilizer. Fertilizer kills flytraps. They need a 50/50 mix of peat moss and perlite with zero additives.
- Respect the Dormancy: When November hits, put them somewhere cold. A garage, a cold windowsill, or even the vegetable crisper in your fridge (search "fridge dormancy" for the specific technique).
Most people fail because they try to be "too nice" to the plant with rich soil and warm rooms. Be a little "mean" to it. Give it crappy, nutrient-free soil and a cold winter. That’s how you get a Venus flytrap that lives long enough to see your kids graduate.
To keep your plant thriving into its second decade, start by checking your water's TDS (Total Dissolved Solids) level; if it's over 50 ppm, switch to distilled immediately. Then, plan for a dormancy period this coming winter by finding a spot in your home that stays consistently below 50°F but above freezing.
