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:
Apply a 2" layer of mulch around plants to reduce moisture loss.
Choose organic mulches, such as shredded bark, compost, or aged sawdust.
Inorganic mulches such as gravel are also acceptable.
