Black Locust can grow in many situations, but prefers dry areas with lots of sun. It is robust and is an excellent choice for establishing shade in dry, open areas.

The Armstrong Maple has a narrow, upright columnar growth habit. This stunning tree has showy leaves that range from yellow, orange to red in the fall. It is an attractive hybrid of the Red Maple and Silver Maple. It prefers acidic soils and will have some tolerance for drought once mature.
