  • Description

  • Notes

This tree will grow 40' tall by 30' wide and has small, light green leaves with clusters of bright magenta fragrant flowers that bloom in spring. Leaves turn yellow in fall and then drop. This upward arching tree tolerates heat as well as cold. Idaho Locust prefers full to part sun and well draining soil. This variety has no seed pods.
Planting Instructions: 1. Dig a hole 2 times the width and 1 and 1/2 times the height of the container. 2. Set rootball just above ground level. 3. Mix soil with 25% amendment and %75 soil. 4. Backfill with amended soil. 5. Build basin and water.
