FAMILY: Fabaceae

This Tree in Colorado:  The crown of the Honeylocust is open-spreading and leaves filter less light than many other species, making this tree a good choice for lawns. It withstands a wide range of conditions, tolerant of drought, high pH and salt.

Growth Rate: Fast growing.

Landscape Use:  The size of this tree varies widely, from 30′ – 70′ high with a comparable spread.

Hardiness:  Zones 4-9.

Leaves:  Compound leaves with 8 to 14 leaflets are bright green in summer and clear yellow to yellow-green in the fall. Leaves fall early.

Flowers:  Between May and June, fragrant but subtle flowers will appear in clusters.

Bark:  Older trees have grayish-brown bark broken up into long narrow ridges and deep furrows.

Insects and Disease:  Cankers and root collar rot are the major diseases of honeylocusts in Colorado. Because these trees are susceptible to these diseases, it is strongly recommended to avoid monogamous planting by using a diversity of trees.
