A classic pond has a form that is reminiscent of earlier styles, such as Renaissance and Baroque, or Roman, Egyptian or even Persian gardens. This type of pond always has a neat, symmetrical form. It can sometimes be circular, but is usually long and rectangular. It can also be a raised basin above ground level. A classic pond usually has a sharply defined, perfectly horizontal stone edge and there is a hard path for walking around it.
On the other side of the path, there are plant borders which often feature plants which sweep back towards a wall or neatly clipped hedge. A fountain or a series of spray features are, of course, all part of the design but they do have consequences for the plants. For example, water lilies find it hard to cope if their floating leaves are constantly splashed with water. Colourful fish, such as goldfish and Ide fish are not happy in choppy water. A classic pond may not have any plants around it; they are often surrounded by spouting, rotating, clattering or babbling water ornaments. Since ancient times, people have known that algae do not grow well running water. An attractive, classic pond does not have any moss or green algae, but clear water and lovely clean edges.
