About
Aesculus assamica is a medium-sized deciduous tree characterized by its large, glossy palmate leaves that emerge bronze before maturing to green and transitioning to orange-yellow in the fall. The flowers are creamy white with a yellow throat that deepens to maroon as they age. After flowering, the tree produces conkers encased in a smooth, thornless shell.
