Japanese rock gardens, influenced by Zen Buddhism, can be found at Zen temples of meditation. They actually have very little plant material and mostly consists of rock, gravel, sand and some moss.
Though they come in all shapes and sizes, they are well suited to small garden landscapes. Japanese gardens have evolved overtime and many of its forms now exist, but the basis of the design still remains the same.
Using the formula of Yin and Yang and other traditional practices, a sense of balance must be obtained in the garden design to keep the basic look of garden.
Japanese gardens can stimulate nature in miniature form, which makes it perfect for small space garden design.
