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:

Consider replacing some lawn areas with groundcovers, trees, and shrubs.

Good candidates for removal are portions of large lawns, areas where no one uses the grass, patches that don't grow well, or spaces too small to water without overspray.
