Taihu Stone: A Complete Guide to Its Facts, Characteristics, Origins and Garden Uses

Taihu stone is an ornamental stone formed by water erosion, mainly produced in the area around Taihu Lake in Jiangsu, which is how it got its name. It was originally limestone, and after long-term washing and erosion by lake water, it gradually developed its unique form of crisscrossing grooves and interconnected holes. Because of its strange shapes and elegant postures, it has been a classic stone in garden landscaping and stone appreciation culture since ancient times.

People often sum up the quality standards of Taihu stone with the four characters thin, wrinkled, leaky and transparent. Thin means the stone is slender and upright, wrinkled means the surface is undulating with many textures, leaky means the holes connect from top to bottom, and transparent means the openings are see-through and the line of sight can pass through. The overall color is mostly grayish white or grayish black, the texture is relatively dense, the lines are naturally winding, and each piece is almost unique.

According to the environment of formation, Taihu stone is divided into water stone and dry stone. Water stone has been washed by lake water for many years, so its holes are rounded and its shape is smooth, and it is usually of higher quality; dry stone is mined from mountain bodies and has relatively obvious edges and corners. When choosing, you can observe whether the holes are natural and whether the stone surface is smooth; there are also stones on the market that have been artificially acid-washed and polished, and their textures often look stiff, so extra care is needed when buying.

In gardens, Taihu stone is often used to stack rockeries, decorate courtyards and create pond revetments, and it can also be set up alone as a landscape focal point. It also often appears in bonsai and aquarium landscaping, adding a touch of mountain wilderness to small spaces. When placing it, pay attention to matching it with the surrounding plants and water bodies, and fix the base well under the stone, so that it can maintain a stable ornamental effect for a long time.
