Gleditsia triacanthos 'Suncole' (Sunburst®) 
The 'Sunburst' Honeylocust is a deciduous tree with a rounded, spreading crown and ascending branches. It is thornless and seedless; indistinct greenish flowers appear in late spring. The fern-like appearance casts a dappled shade with bright yellow foliage that fades into a rich green in the summer. It prefers well-draining soil and can withstand low levels of drought. The unique foliage makes it a perfect stand-alone tree in any size garden.
