These low-maintenance, high performance plants add color and life to beds, borders, pathways, and patios. Most effective when planted in large swaths, the majority spread on their own and grow in dense fashion, which gives them the considerable advantage of suppressing weeds. Here we have included low-growing ground covers for sun or shade, and for dry spots or moist ones. Plant a single variety to create a uniform look, or choose several to craft a mosaic pattern.
