Paul James, host of HGTV's Gardening by the Yard, offers tips on using stone in the landscape. Mention landscaping, and most people think of plants. But many landscapes also include hardscape features such as paths, walls and structures. One of the most popular hardscape materials is rock -- perfect for constructing borders, terraces and walls. Few materials give a garden as great a sense of permanence, and few last as long. Rock is an excellent choice for paths and patios. Rock projects -- from a meandering flagstone path plopped down on a bed of mulch to an elegant patio for outdoor entertaining -- can be created to fit any gardener's budget or skill level. When combined with plants, large and small rocks can transform an otherwise ho-hum landscape into something special. Whether used as focal points or accents, they can change the character of a landscape like no other material. Incorporated into water features such as ponds and waterfalls, rock can convey the impression of raw nature and set a mood that is tranquil yet powerful. What's the difference between rock and stone? In their natural setting, they're rocks; when we bring them into the garden, they're stones. Each has its own individual character. For a patio or pool deck where you want tables or chairs, select smooth, flat rocks so that chairs can be scooted easily. If rock is to be used to add character to the garden, look for rustic, weathered stones covered with moss. If you're building a fishpond, choose natural and outdoorsy-looking rocks with attractive colors. In the Tulsa garden of Brad and Jody Porter are rocks of all shapes, sizes, thicknesses and colors, from small chunks of gravel to lichen-covered boulders weighing as much as two tons. For 20 years Brad has designed and installed rock-garden features of all kinds, and he and Jody sell rock projects. Types of stone include the following: - Building stone, used for fireplaces, new houses and fenceposts;
- Flagstone, generally a thin, flat stone used for steppingstones and patios;
- Decorative boulders, which work well for waterfalls and around fishponds; and
- Decorative gravel, often used as a groundcover.
