Description

This very fast-growing deciduous tree will grow 40-75' tall and 30-60' wide. It has blue-green or light green leaves with fragrant white flowers in the spring. Thorny branches, hard wood and heavy sucker production make the Black Locust a challenging maintenance project.

Water-wise plants can be beautiful as well as practical.

Ask at your local nursery for the types of plants that have minimal watering needs.
