What ground cover can a I plant to stop an eroding slope? Sun most of the day, clay soil. I would like something that blooms. I don’t want to put rip-rap on it.
The Gardener’s Answer
Hi, Carol: Landscaping a slope with perennial groundcovers is a good way to prevent erosion. The roots of these low-growing plants will spread and help to keep the soil intact. It will become a low-maintenance space that does not require mowing. Sun-loving options that bloom include stonecrop sedums, perennial geraniums, creeping phlox, lysmachia, creeping thyme, vinca, and dianthus. They all have their own specific bloom times but similar growth habits. Perennials do not bloom as long as annuals but incorporating a few different groundcovers with different blooming periods will provide color throughout the growing season. It would not make sense in a smaller area but if you have significant space to plant, you may consider choosing more than one option. I hope this is helpful.
