Plants for hedges are shrubs that grow straight up rather than spread along the ground and have a width that is about the same as the height of the plant. Shrubs are very adaptable plants, since they are able to be pruned and trained to grow in different ways. When shrubs are planted close together, they grow up more than they do wide with each one blending in with its neighbors to form a hedge.
