Research performed by Dr. Roger S. Ulrich of Texas A&M University, Helen Russell of Surrey University in England as well as those conducted by Dr. Virginia Lohr of Washington State University verify that plants significantly lower workplace stress and enhance worker productivity.

In Dr. Lohr’s study, common interior plants were used in a computer laboratory with 27 computer workstations. A computer program to test productivity and induce stress was specifically designed for these experiments. Participants working in an environment with plants present were 12 percent more productive and less stressed than those who worked in an environment without plants.
