If you have this plant in your house, then you have…

You have likely seen headlines such as: “If you have this plant in your house, then you have good luck!” or “…then you are breathing cleaner air!” These catchy phrases circulate widely on social media and lifestyle blogs, often attributing mystical, health-related, or spiritual benefits to common houseplants.

While such claims are engaging, they rarely tell the whole story. Without knowing which specific plant is being referenced, it is impossible to evaluate the statement accurately. However, examining a few popular examples reveals a helpful pattern: many plant myths contain a grain of truth, wrapped in layers of exaggeration.

Here is what science and tradition actually say about some widely celebrated houseplants.

If You Have a Snake Plant (Sansevieria)

The claim: “…then you have cleaner air!”

The reality: Research from NASA’s Clean Air Study did find that snake plants can remove trace amounts of certain indoor pollutants, such as formaldehyde and benzene. However, the study was conducted in sealed laboratory chambers, not typical homes. To achieve air-purifying effects comparable to a mechanical air filter, you would need an impractical number of plants—estimates suggest more than ten per square foot.

The balanced take: While a single snake plant will not transform your indoor air quality, it is undeniably low-maintenance, resilient, and visually striking. Its presence adds greenery, which studies show can support mood and reduce stress. That is a meaningful benefit, even without the superlatives.

If You Have a Money Plant

The claim: “…then you have prosperity coming your way!”

The tradition: In practices such as Feng Shui and Vastu Shastra, plants like pothos and jade are symbolically associated with abundance, growth, and positive energy. These beliefs are culturally significant and personally meaningful to many.

The reality: There is no scientific evidence that a plant can influence financial outcomes. However, these species are famously adaptable—they tolerate low light, irregular watering, and beginner-level care. Their resilience makes them excellent choices for new plant owners, which may indirectly support a sense of accomplishment and well-being.

If You Have Lavender

The claim: “…then you sleep better and feel calmer!”

The research: Lavender’s aroma has been studied for its potential to promote relaxation. Some clinical trials suggest that inhaling lavender essential oil may modestly improve sleep quality or reduce anxiety in certain individuals.

The nuance: These effects are typically observed with concentrated essential oils used in controlled settings, not merely from having a potted lavender plant nearby. That said, the gentle scent of lavender, combined with the ritual of caring for a plant, can contribute to a calming environment. The benefit is real, but it is subtle and supportive—not curative.
