Phytoremediation
That spider plant or pothos sitting on your desk isn't just decoration — it may be actively scrubbing the air of chemicals you can't smell, and this study gives you a ranked shortlist of which species actually pull their weight.
Scientists set up four popular houseplants in a real lab where chemicals like benzene and toluene were present in the air — the kinds of fumes that can cause headaches and long-term health problems. They measured how well each plant cleaned the air and how stressed the plants got doing it. The ti plant came out on top, clearing nearly nine out of ten units of harmful chemicals, while spider plant and pothos also performed well, making all four solid choices for cleaner indoor air.
Key Findings
Cordyline fruticosa (ti plant) removed 87.50% of VOCs, 88.23% of CO, and 36.78% of CO₂ — the highest of all four species tested.
Ti plant had the highest Air Pollution Tolerance Index score (14.76%) and the densest stomata (94.34 per mm²), traits linked to superior pollutant uptake.
All four species — ti plant, arrowhead vine, golden pothos, and spider plant — showed measurable phytoremediation ability in both pot and green-wall configurations.

Researchers tested four common houseplants in a pharmaceutical lab filled with chemical fumes and found that ti plant (Cordyline fruticosa) outperformed the others, removing up to 87.5% of volatile organic compounds while also tolerating pollution stress better than its competitors.
