Below, we focus on Gleditsia triacanthos ‘Skyline’. This cultivar is usually grown as a tree.
The tree is widely used in residential streets, avenues, roads, and parks. It is also frequently planted in squares and shopping districts in European city centers. We do grow this cultivar as a shrub, but its use remains somewhat limited.
The tree forms a beautiful pyramidal to umbrella-shaped crown that does not produce thorns and may not produce pods until it reaches maturity. The tree is known for its open crown, often featuring characteristically whimsical branches, which is particularly noticeable in winter. People appreciate its open structure, beautifully pinnate leaves, and stunning golden-yellow fall color. In the summer, the sun plays through the small, pinnate leaves.
This cultivar was introduced by Cole Nurseries in Ohio (1957). Another highly versatile cultivar is Gleditsia triacanthos’Sunburst’. The leaves of this tree emerge in a beautiful golden-yellow color and later turn a light green. We often grow this cultivar as a multi-stemmed shrub. As a shrub, Gleditsia triacanthos ‘Sunburst’ typically grows more attractively than the ‘Skyline’ cultivar.
