Engaging Introduction
If you have this plant in your house, you already own one of nature's most powerful air purifiers. Known scientifically as Sansevieria trifasciata and commonly called the snake plant or mother-in-law's tongue, it's admired for its striking appearance and incredible health benefits. Beyond its beauty, this plant silently works to improve your environment, making your home healthier and more peaceful.
I first bought a snake plant on a whim. I was at a garden center, looking for something—anything—that I couldn't kill. I had a reputation for being a plant murderer. Succulents withered. Ferns browned. Even my hardy pothos looked at me with disappointment.
A clerk pointed to a tall, sword-like plant with striking yellow-edged leaves. "This one," she said, "is unkillable."
I was skeptical. But I bought it anyway.
That was seven years ago. The snake plant has survived my neglect, my overwatering, my underwatering, my moving it from room to room, and a brief period when I forgot it existed behind a bookshelf. It's still thriving. It's grown so tall that it nearly touches the ceiling.
And along the way, I learned that this nearly indestructible plant is also quietly working to make my home healthier.
Let me share why the snake plant is such a blessing—and why you should consider adding one (or several) to your home.
First, What Is a Snake Plant?
The snake plant (Sansevieria trifasciata) is a perennial evergreen native to West Africa. It's characterized by its tall, upright, sword-shaped leaves that can grow up to 4 feet tall. The leaves are dark green with lighter green zigzag bands and often have yellow or white edges.
Common names: Snake plant, mother-in-law's tongue, devil's tongue, St. George's sword.
Why "snake plant"? The wavy, pointed leaves resemble the pattern and shape of a snake's skin.
Why "mother-in-law's tongue"? The sharp, pointed leaves are a playful (if slightly unkind) reference to a mother-in-law's sharp tongue.
Growth habit: Snake plants grow slowly but steadily. They spread via underground rhizomes, so they can eventually fill a pot.
