Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Idaho Locust is a medium sized tree that grows to about 40 feet tall and 15 to 20 feet wide. Small, light green pinnate leaves turn yellow in autumn. 6 to 8 inch long pendents of rose-pink, fragrant flowers bloom in spring. Idaho Locust has a more open habit than Black Locust, and it has few or no seed pods, but it does have thorns.
