What you describe sounds like lichen and it won't harm your plants but it does look a bit odd. There's not much you can do to stop the lichen growth although some gardeners peel it off the bark. Depending upon the type of shrub you have, you may be able to use a lime/sulfur spray to control the lichen. If your shrubs are evergreen, don't use lime/sulfur. It could burn the foliage. If your shrubs are deciduous you can spray them with lime/sulfur in the winter, after all the leaves have fallen off. Best wishes with your shrubs.
