Ornamental shrubs are plants that are grown for their aesthetic value and are often used in landscaping. Alders, yews, acacias, spireas, hollies, and smilaxes are all examples of ornamental shrubs. Alders are deciduous trees or shrubs with toothed leaves and catkins, while yews are evergreen shrubs or trees with flat, dark green needles. Acacias are flowering shrubs or trees with small, yellow or white flowers, while spireas are deciduous shrubs with clusters of small white or pink flowers. Hollies are evergreen shrubs with spiny, glossy leaves and red berries, and smilaxes are woody vines with small, fragrant flowers.
