30 Gorgeous Rock Garden Ideas for Easy Outdoor Style

Rock gardens offer an opportunity to create a visually dramatic landscape and even a low-maintenance solution to awkward spaces such as a steeply sloped front yard. The choice of rock can set the tone for the garden — will you go with terracotta stones that complement a tropical landscape, lava rock for a modern look? Or will you use what nature provides, as in this rock garden designed by LDAW Landscape Architecture PC that's filled with boulders and overflowing with lush sedums.

Plant choice, of course, is key in rock garden design. Grasses, sedums and mungo pines look at home in rock gardens, which often are placed in sunny areas. Lavender, California poppies, cheddar pinks dianthus, shasta daisy, creeping phlox, agave and thyme are among the variety of plants that thrive in the warm and well-drained growing environment offered by a rock garden.

Mix rock sizes and shapes to create interest. Consider pairing boulders with smaller river stones, or create a daring palette for your rock garden by using pea gravel and colored glass pebbles.

Two great plant groups to draw from when designing your rock garden are ornamental grasses and evergreens. Both of these plant types blend beautifully with stones to create a planned-by-nature look. Better still, both groups feature low-maintenance plants. This rock garden showcases undaunted ruby muhly grass (Muhlenbergia reverchonii ‘PUND01S’), a drought-resistant plant. Good evergreen choices with a low profile include dwarf blue globe (Picea pungens ‘Glauca Globosa’), bird’s nest spruce (Picea abies ‘Nidiformis’) and mugo pine (Pinus mugo).

Rock gardens on a slope or raised bed provide a warm growing environment and sharp drainage, which is ideal for plants like lavender (Lavandula) or California poppy, also known as golden poppy (Eschscholzia californica). Both of these pretty flowers self-sow readily in a rocky area, creating serendipitous drifts of color.

You don’t need a large-scale rock garden to enjoy the style. With a small rock garden, you can play with mulches and plant arrangement in ways that let you create changes over time.
