The Story
Plant Bio
The London Planetree is a large, majestic deciduous tree, a hybrid between the American Sycamore and the Oriental Planetree. It is famed for its beautiful, exfoliating bark that reveals patches of cream, olive, and gray. 'Morton Circle', sold as Exclamation!, is a cultivar selected for its strong central leader, uniform upright-pyramidal habit, and excellent resistance to anthracnose and frost cracking. Its form is much more uniform and dense than the species.
