Exclamation!™ ('Morton Circle') London Planetree is a hybrid selection by Dr George Ware at the Morton Arboretum.  The controlled cross is between our native Sycamore and the Asian species.  Platanus x acerifolia Exclamation!™ gets its name for its very upright pyramidal in the winter landscape.  In addition to its very upright regular straight habit, Exclamation!™ is also resistant to both Anthracnose and frost cracking, so it makes a very versatile fast growing shade tree which tolerates a broad spectrum of site conditions.  Introduced by Chicagolad Grows®.
