Combine weathered wicker furniture with floral cushions to create a peaceful Japanese Zen garden. Opt for cushions with subtle floral patterns in calming colors. Keep the furniture arrangement minimalistic and symmetrical. Surround the furniture with Japanese maple trees, bamboo, and a small Zen rock garden. Add some lanterns and a bamboo water fountain to enhance the Zen atmosphere. This combination will bring a sense of tranquility and harmony to your garden.
