I am a big fan of the Japanese Garden. The use of rock, water, and plant elements as part of a trinity of symbolism and metaphor. Heavy with dwarf conifers, large boulders, koi ponds, and waterfalls, the landscape is a place that causes a person to sit for a time and connect with their natural world.
There are many studies confirming water’s calming effect in the home and office environment. I visited the Anderson Japanese Gardens in Rockford, Illinois early June of 2014. Below are a few photos of some of their water features.
