chicagoland grows® Plant Introduction Program

Exclamation!® London Planetree

Platanus x acerifolia ‘Morton Circle’



With its strong central leader, uniform upright pyramidal shape, attractive exfoliating bark, vigorous growth rate and excellent resistance to anthracnose and powdery mildew, the Exclamation!® London Planetree is a superior choice for tough urban settings. It has exceptional tolerance to poor soils, extended flooding or drought, and air pollution. Exclamation!® works very well in large parking lot islands, median strip plantings, as a residential street tree, or as a landscape shade tree. From a controlled cross by Dr. George Ware at The Morton Arboretum in Lisle, Illinois. Mature size may approach 60’ tall by 45’ wide. Hardy to USDA Zones 4 – 8.

This has been the top selling tree in the program since 2015.
