Originating from China and Indochina
With its highly unusual large and broadly lobed leaves and green/orange tulip shaped flowers this is a tree of outstanding garden merit. Possibly a good candidate for hard pruning in order to produce the largest purple tinted vigorously growing foliage, this is a great species for medium sized jungle and exotic style gardens.
If left to form its full size, its impressive broad and dense crown is better seen with space around it in a larger garden. Easily grown in all soils in sun or part shade.
Height and spread after 5-6 years 4m x 3m.
Semi mature height and spread after 10 – 12 years 8m x 4m
Potential mature height and spread after 40 years plus 15m x 10m
