One of the most popular yellow leaved ornamental trees, Gleditsia triacanthos 'Sunburst' is favoured for its vibrancy, small size and versatility. The arching branches are clothed in golden yellow, small pinnate leaves that turn a lime green in the summer and then clear yellow in the autumn.
The tree has a slightly spreading form and will grow to just 5 x 3 metres in 20 years. It will do well in most soils that are free draining in sun or part shade. Some exposure can be tolerated and pollution isn’t a problem.
Known as a Golden Honey Locust, 'Sunburst' is an award-winning small tree that will make a big impact with its bright, light, feathery foliage.
AKA Golden/Yellow Honey Locust, Gleditsia triacanthos f. inermis 'Sunburst'
Our pot grown Honey Locust 'Sunburst' trees benefit from being suitable to plant at any time of year. Begin by removing weeds and grass within a metre of your desired planting hole, then dig a square hole as deep as your root mass and approximately 2x as wide. To help Gleditsia establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees).
Gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems. Add a stake and tie to prevent root rock and allow the tree to establish more easily.
If you’re planting Golden Honey Locust in spring, summer or dry weather, water well and regularly for the first few months. Keep an eye on young trees and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little.
Once Gleditsia is planted, keep the area free of competing weeds and grass for the first couple of growing seasons. Installing mulch matting will aid in this. Do not simply mow the grass around the area as this will only encourage it to grow more vigorously. If your area is prone to rabbits, we advise using a rabbit guard.
Yellow Honey Locust trees do not require regular pruning. If you wish to tidy up 'Sunburst', do this during the dormant season. Focus on removing any damaged, diseased or overcrowded branches. If you require a clear trunk, remove any side shoots to help raise the crown.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. *Pot sizes may vary. Below are definitions of terms:
Supplied Size: Height measured from the top of the pot.
Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.
Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.
Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.
Multi Stem: A multi stem tree has two or more stems arising from or near ground level, growing from one root system.
Bush: A plant with many stems low down, rather than one clear stem.
Clump: Several plants in one pot that can give the appearance of a multi stemmed and very bushy tree.
Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.
Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branches of the crown). Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height:
