The landscaping surrounding the library was designed to be attractive but also to have less of an impact on the environment.
Choosing species of plants that are native to the area can help in a number of ways. They are more drought tolerant and need less watering. They are less liable to be impacted by pests and will not require pesticide use.
As you walk around the library you will notice grasses, cotoneasters, blueberries, and magnolias.
