According to Plants At Work, a "national information campaign
working in conjunction with the industry to inform professionals
and the public about the numerous benefits of interior plants",
the multiple advantages of plants in the workspace far outweigh
"Plants in the workplace offer more than aesthetic value. In
fact, studies have shown they help reduce stress, enhance
employee attitudes, increase productivity, and improve air
"Plants offer a means to decrease stress while enhancing
productivity by 12%."
"...plant transpiration in an office environment releases
moisture, creating a humidity level exactly matching the
recommended human comfort range of 30-60%."
"According to literature from the Associated Landscape
Contractors of America, proper selection and placement
of plant materials can lower heating and cooling costs
by as much as 20%."
"Research shows that plant-filled rooms contain 50-60%
fewer airborne molds and bacteria than rooms without plants."
"Strategically placed, plants quiet down an office."

On a more personal level, my supervisor, in the last office
in which I worked, once gave me a large, bushy philodendron
on the occasion of some achievement on my part. I appreciated
it much more than any of the inanimate plaques, cards, and
other objects I received on other occasions. She passed away
a couple of years later. I still have the plant in my living
room over 5 years later, having taken it with me when I left
that position. It has always brought me joy and fresh air.
