About Robinia ‘Idahoensis’ (Idaho Locust)

This beautifully fragrant tree is known as Robina ‘Idahoensis’. Commonly known as Idaho Locust, this deciduous tree has green lanceolate shaped leaves that turn yellow-green in the fall and offers flowers and fruit through various seasons of the year. In the spring, clusters of pea-like pink flowers bloom that are as showy as they are fragrant. In the fall, brownish-green pod shaped fruit emerge that drop throughout the season. Reaching an average mature landscape size of 20-30′ x 20-30′, this tree grows at a moderate rate and has an upright oval form. Inviting birds, bees and butterflies, this tree is a great local pollinator.

Planting and care instructions

Plant Idaho Locust using well draining soil in an area that receives at least six house of full sunlight. Water regularly after planting to help establish its roots, then reduce frequency. Once established, this tree is drought resistant. As its fruit drops throughout the fall season, sweep the surrounding area for a tidy appearance. If desired, cut back branches in the early spring before new growth begins to emerge.

Landscape design ideas

Robinia ‘Idahoensis’ is a practical choice for cities to use in local parks or street medians. This tree is great for California landscapes looking to reduce water usage and for residential landscapes, a thoughtful option for cottage style gardens.
