Bay hedges, or Laurus nobilis, are evergreen hedges with fragrant, dark green foliage that adds both beauty and practicality to any landscape. They can grow up to 20 feet tall, are low-maintenance, and can be easily pruned to maintain a desired height and shape. Bay hedges are popular for their culinary uses and can be used to create natural barriers for privacy, sound reduction, and wind protection, as well as for topiary designs.
