Robinia pseudoacacia
Black Locust
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 Saving Tip:
Watering every day results in shallow roots.
Instead, water deeply every few days using the Cycle and Soak method (two or more short run times, each separated by about an hour).
