Create a vertical accent in your landscape with narrow, evergreen shrubs. Grown in a wide variety of colours and sizes, narrow evergreen shrubs are taller than they are wide, creating a bold architectural line in your landscape. As evergreens, they retain most of their foliage year-round, making them a constant source of vibrancy. Planted side-by-side or used as a specimen shrub around the garden, narrow evergreens provide a special presence to the home and garden.
