A ground cover plant’s ability to spread on the soil under shrubs and trees makes it an important ingredient in a garden’s ecology. These plants keep moisture in the ground and weeds out of the way – a hugely important task. While some are faster growing than others and some are at times invasive it is important to establish a layer of ground cover from the outset. At times, the planting design calls for a mixed elevation of colours and textures. At other times, a more minimalist approach may call for a simple carpet of one or two species. With the latter, it is therefore important to select the right plant for the task as be it shade or sun there would be only one plant to highlight the main accent tree or shrub.
