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:
Give your sprinkler system a checkup when turning it on in the spring and occasionally during the summer.
Trim branches that are obstructing spray patterns and raise sprinklers that are too low for spray to clear the grass.
