They light up our home and our office.
But indoor plants also purify the air we breathe.
Studies have shown that popular potted plants also absorb dangerous chemicals and make it cleaner for us to breathe air.
One of the best "natural air fresheners" is Zhu Hongxing, a brightly colored tropical pineapple that blooms indoors for months.
Other plants include the corn plant (the Mexican dragon blood tree), which has long and mixed-colored leaves and is particularly good at removing the spicy chemical acetone from the nail polish defacing agent.
The work is carried out at a time when there is growing concern about the damage caused by indoor air pollution, including toxins known as volatile organic compounds, or from paint and printers to clean chemicals and drying-The clothes are cleaned.
The Royal College of Physicians estimates that indoor air pollution kills 99,000 people in Europe each year.
In addition, many people think they have "sick building syndrome" in which stagnant, polluted air triggers everything from headaches to skin allergies and fatigue.
Researchers at the State University of New York said: "buildings, whether new or old, may contain high levels of VOCs, and sometimes you can smell them.
Scientists have placed five different potted plants in a sealed chamber full of VOCs and monitored how the content of the chemical changed over time.
Testing of 5 common indoor plants and 8 VOCs found that some plants are better at absorbing specific compounds.
For example, all 5 plants can remove the spicy chemical acetone contained in the nail salon, but the dragon blood tree plants occupy the majority, accounting for about 94 of the chemical. The best all-
Round circle is the red star of bro and a member of the pineapple family.
Dr Vadoud Niri, head of research, said: "Based on our findings, we can recommend which plants are good for certain types of VOCs and specific locations.
To illustrate, pineapple plant is very good at removing six of the eight research VOCs
It can occupy more than 80 of each of these compounds --
During the sampling period of 12 hours.
So sitting at home or in the workplace can be a good plant.
At a meeting of the American Society of Chemistry, it was heard that the other three plants studied were emerald plants (Crassula, Argentina), spider plants (hanging orchid) and Caribbean tree cactus (lollea falcata)
The Royal Horticultural Association says potted plants bring many benefits.
Dr. Tijana Blanusa, RHS's leading horticultural scientist, said: "The psychological benefits of indoor plants have been revealed by improving people's exposure to their emotions, reducing stress levels, and improving the productivity of workers in the working population, improve pain tolerance, for example, using plants in hospital settings.
"Indoor plants can also bring some health benefits, including the removal of pollutants in the air, thus improving indoor air quality and physical health.
