The leaves are also finely serrated, giving them a delicate and graceful appearance.

They are also rich in vitamin C and are a valuable source of nutrition for both humans and wildlife.
The Glaucous Dog Rose prefers full sun or partial shade and well-drained soil. It is a relatively hardy plant and can tolerate a range of soil types, from sandy to clay. It is a low-maintenance plant that requires little pruning, although it can be pruned in the late winter or early spring to remove any dead or damaged wood.
