Many things originated in China. Bonsai is a good example. Another is Zen. The principle of Zen started with the Mahayana Chinese Buddhists in the time of the Tang Dynasty (thank you, Wikipedia). It eventually moved south to Vietnam, up to Korea and eventually settled in silence in Japan where it was obviously perfected.
The meaning of Zen, about which many books have been written over time, simply means a rigorous self-control, meditation practice and an understanding and insight into Buddhist nature, which is expected to be applied to all else and others. Hence the spartan presentation of a Zen garden that in its simplicity is inspirational, a touch of what we would call modernism and an irrefutable effect on your ideas of order.
Zen gardens were also often miniature landscape spaces where there was limited room to have a garden that could connect with daily utterances, prayers and offerings (and to show off a bit too).
Zen gardens often use just one lonely plant (quite often a conifer), robust enough to withstand the rigours of any weather, perfectly shaped and tended to be in excellent health for its very long life that often fell to a following generation to tend.
Stones and rocks are as important as the plants, as these represent structure and islands. Each is carefully selected for the purpose and can take a long time to position correctly to reflect its purpose as one among a whole dry landscape. Flat stones represent water, upright stones trees.
Carefully tended moss on rocks also demonstrates control and order (possibly with a pair of grass tweezers). Likewise, bamboo fencing is an essential element and must be of even quality within each culm and colour matched before it is exquisitely woven for a fence.
Carefully raked sand and pebbles form the base of the garden. This again, demonstrates order and an offer of meditation, introspection and discipline in keeping raked shapes such as circles in the sand. Usually followers use an equally crafted rake for the purpose, but you can use a standard steel rake if you have one.
Water is not a part of a Zen garden, nor technically, should a Zen garden be located near water. The Zen garden is a dry landscape that uses elements such as rocks, bamboo, sand stone and usually low-spreading plants.
Yours can be a small corner that has some surrounding shelter and with just a few of the elements. In effect, a Zen garden would be the lowest of low-maintenance gardens, but high in spiritual and nano control features.
