Having plants, going for a walk in the park, or even looking at a landscape poster could produce psychological benefits, reduce stress, and improve concentration.

Based on several experimental studies, the presence of potted plants has been found to be helpful in many different settings including work, school, and hospitals. In particular, plants have been shown to lower blood pressure (systolic), improve reaction times, increase attentiveness, improve attendance (at work and school), raise productivity (at work), improve well-being, improve perceptions of the space, lower levels of anxiety during recovery from surgery and raise job satisfaction.

Not bad, huh?! Feeling good around plants is probably not surprising. After all, we surround ourselves with plants during celebrations and tragedies (i.e., weddings and funerals, respectively). We also set aside "sacred" green space for parks

and community gardens
