Three Cheers for Houseplants
Three Cheers for Houseplants
Those unsung heroes that brighten our homes and office spaces
By Marion Owen, Fearless Weeder for PlanTea, Inc. and
Co-author of Chicken Soup for the Gardener's Soul Source
DID YOU KNOW that the hardest working occupants in our homes and offices don't have arms or
legs? They don't do dishes, mow the lawn or answer the phone. They go about their duties in
complete silence, 24 hours a day, 7 days a week. And if that isn't enough, they demand nothing in
return. Yet, what they do for us deserves a Medal of Honor!
I'm speaking of houseplants, those African violets and ferns that grace our living rooms and desks
without so much as a peep.
Not everyone shares my enthusiasm for plants, though. Take Jerry Seinfeld, for example. After
reading the following comment about houseplants, you'll wonder if he even allows plastic ferns on
the set while taping the show.
"I have no plants in my house. They won't live for me. Some of them don't even wait to die, they
commit suicide."--Jerry Seinfeld
Jerry Seinfeld notwithstanding, houseplants deserve to be elevated above the status of green
statues. We should consider houseplants our friends. Why's that? Mostly because they help us
breathe. Not by pushing on our chest or giving us mouth-to-mouth resuscitation, but by filtering out
indoor air pollution.
Now in case you're thinking you don't have to worry about indoor air pollution because you don't
smell anything bad, read on.
We breathe about 20 times per minute, more than 10 million times per year, which adds up to
about 700 million breaths in a lifetime. That's a lot of inhaling and exhaling and each breath
reminds us how important clean air is to our overall health. Most of us don't give indoor air pollution
a second thought since there's so much emphasis on the ozone layer, the greenhouse effect, acid
rain and so on.
But we should think about it more often, especially since the average person spends 90 percent of
his or her time indoors.
Plants to the Rescue
Have you every walked into a new house or office building and was almost knocked over by the
strong odors? You weren't imaging it. In 1984, a World Health Organization report suggested that 1
out of 3 new and remodeled buildings may have poor indoor air quality -- enough to cause
headaches, eye, nose, or throat irritations, dry coughs, dry or itchy skin; dizziness and nausea.
They even gave this situation a name: Sick Building Syndrome.
About the same time, NASA scientists were studying ways to combat indoor air pollution. Recent
studies have proven that oxygen boosts the brain's performance. You know how lethargic and
mentally foggy you feel after riding in a plane with poor air circulation for four hours? A breath of
fresh air does the trick. But astronauts can't just step outside for some fresh air. Fortunately, the
2-year study discovered a practical, pollution-absorbing device: the everyday houseplant.
The plants used in the study absorbed contaminants from the air so efficiently, even the scientists
were surprised. Soon, plans were made to launch plants into space. Scientists wanted to see how
they'd perform as part of the life support system aboard orbiting space stations. Imagine, a rubber
plant in a space suit...
Plants as Air Conditioners
Plants take substances out of the air through their stoma, the tiny opening in their leaves. Recent
studies have shown that plants not only breathe through their leaves, but roots and soil bacteria
also remove trace levels of toxic vapors. In goes the bad air, out goes the good.
So, what kind of toxic vapors are we talking about? And are they limited to just new buildings?
Besides the obvious culprits like cigarette smoke, and diesel and propane fumes, invisible and
odorless compounds leak from counter tops, furniture--even the chair you are sitting in.
Let's start with formaldehyde. Some of you might remember formaldehyde from your high school
science classes as the smelly substance used to pickle specimens for dissection. This chemical is
found in virtually all indoor environments. The nastier form is called urea- formaldehyde, or UF. It is
found in foam insulation, particle board and pressed wood products used in desks, tables, shelves
and other office furniture.
Formaldehyde is also used in making paper bags, waxed papers, facial tissues and paper towels.
Many of these products are treated with UF resins. This is why unbleached coffee filters, paper
napkins and paper towels are finding their way into mainstream retail stores. Consumers are
demanding safer, dioxin-free paper products.
Sources of Fumes that Cause Indoor Air Pollution
The list of guilty products continues. Many common household cleaning agents contain
formaldehyde. UF resins are used in wrinkle-free treatments, fire retardants and adhesive binders
in floor coverings, carpet backings and permanent-press clothes. Other sources of formaldehyde
include natural gas, kerosene and cigarette smoke.
Then there's benzene. Benzene is a common solvent and is present in gasoline, inks, oils, paints,
plastics and rubber. It is also used in the manufacturing process of detergents, explosives,
pharmaceuticals and dyes.
Last but not least, we have trichloroethylene. Trichloroethylene is a big word that demands we
sound it out slowly when trying it on for the first time. TCE is used in the metal degreasing and dry
cleaning industries. You'll also find it in printing inks, paints, lacquers, varnishes and adhesives.
A Houseplant in Every Home and Office?
Fortunately, there are simple ways to diminish the effects of indoor air pollution. Start by becoming
an informed consumer. Read the lables and buy smart. Second, let's get back to those hard
working houseplants.
After NASA told the world how well plants vacuum-cleaned the air in our homes and offices, people
bought ivy plants, Boston ferns, and spider plants from garden centers, florists and grocery stores.
Now, 75 percent of all households have at least one indoor plant. And to think that it wasn't long
ago when folks believed indoor plants robbed oxygen from the atmosphere, making it unsafe for
human inhabitants.
I starting writing this article as a "houseplant care" article. But it seemed pointless to talk about how
to take care of indoor plants, without first explaining why you should bother, or even care.
That African violet sitting on your kitchen windowsill is much more than a green statue sitting
around, doing nothing for its room and board. Plants are more than decorations for your home or
office. Plants not only filter air, but they ease tension and reduce stress. Studies show that their
presence in hospitals--or even having a view of plants or trees through the window--helps patients
recover more quickly from illnesses and surgery.
If you own houseplant, consider yourself fortunate to have such a useful being around. Treat it like
a member of the family and spread the good word by giving plants as gifts. The recipient will enjoy
its beauty long after the bloom has faded from cut flowers.
And, by all means, take care of your hard-working roommates. Feed them a mild, organic fertilizer
during the growing season. Transplant them every two years or so, and pay attention to their water
needs. By the way, it's better to err on the dry side. Provide good air circulation, dust them off
occasionally, watch for pests, and give them plenty of light. And you might consider treating them to
a little Mozart once in a while.
