The Sunburst honey locust is native to the midwestern United States where it grows in moist and winter-cold locations. It is a fast growing tree with an arching branch habit, reaching 35-50 ft. tall, 30-35 ft. wide. The new growth of this cultivar is bright yellow and very attractive. Flowers are inconspicuous; clusters of 12-18 in. long flattened brown bean-like seed pods ripen by end of summer.

Sunburst honey locust has proven to be a tough and highly adaptable tree that is grown for shade in parks and gardens across the Inland Empire. It is best adapted to loam soils, and with regular summer moisture it has proven to endure sun, heat and aridity. Mature trees will endure short periods of summer drought. It is widely appreciated for it's graceful branching habit and moderate shade during the summer.

Water Needs

The Sunburst honey locust grow best in the Inland Empire with moderate amounts of water on a monthly basis throughout the year. Deep watering is recommended for good rooting depth and to help maintain good foliage character. It should be noted there are several winter months marked by an asterisk (*) when rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water depending upon exposure conditions and size.
