Most beds and borders are at ground level, involving much stooping and bending. A raised bed can mean easier work and closer appreciation of small plants. There are many styles of raised beds that can be purchased from many suppliers at differing price levels and differing quality. They may extend right along the length of a wall or fence, it can be a large, deep raised bed, or small and shallow housing tiny alpine plants.
All types of plants, except deep-rooting trees, can be grown in raised beds, according to the depth: roses, Iow-growing shrubs, miniature conifers, hardy and half-hardy annuals, perennials and bulbs of all kinds. Rock-garden plants are particularly suitable for a small raised bed.
