Border and lawn edging plants are used to define areas. Solid color plants better define gardens or landscapes where lots of colors and textures are being used, while multi colored plants work perfectly as borders to monotone color gardens or bare landscapes. Spreading, or draping, border plants will creep into the garden or landscape mixing with the other plants or spill over the edge of the garden bed. They work well in any garden setting, but really show their talents when planted along the edge of a multi-level garden.

Along the edge of gardens, landscapes, or paths is a key spot to introduce new colors or textures. Contrasting border plants with colors used in the setting make areas pop. Brilliantly colored plants such as the Heucheras or Black Mondo Grass offer unusual colors and work as contrasting companion plants.
