The first plant in Japan's dry landscape

Quick answer：

The first plant in Japan's dry landscape, also known as Zen rock garden or karesansui, is typically not associated with a single plant species. These gardens typically use rock arrangements and raked gravel or sand to represent mountains and water, and they may incorporate a variety of plant materials such as mosses, grasses, and bamboo. The choice of plants is often influenced by their ability to withstand harsh conditions, as these gardens are meant to evoke a sense of serene natural scenery with minimal use of living plants.
