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:
In shrub areas, convert from spray sprinklers to bubbler or drip systems that apply water directly to roots.
Occasionally check the soil's moisture level around shrubs before and after watering to determine if watering times are appropriate.
