Groundcovers are low-growing plants used to cover bare ground and prevent the growth of weeds. They also can be useful in problem areas, such as slopes where mowing grass would be difficult. They’re useful in any garden—public or private—and they provide an ornamental layer as well. There are many groundcovers available. Some do well even in full shade, others in bright sun, in wet soil, under dry soil conditions, where deer are a problem, and many are practically disease resistant. Come for a walk through the Winterthur Garden and see how the horticulturists put groundcovers to work.
