Attractive flaking cinnamon bark, leaves with three leaflets, green above, silvery below, with some coarse teeth. Fall color is brilliant red, though the crown is sparse. Rows of raised planters behind Old Chemistry feature multitrunked specimens from 2016. Nine remain of trees in the inner courtyard of Crothers Hall, near the building entrances, planted in 2010. Four older transplants endure in the lawn on the left of the Mausoleum.

Campus’s handsomest established specimen is at the right corner of the front of Lou Henry Hoover House. See the region’s champion in size and beauty on the left of the back porch of Gamble Garden House in Palo Alto.
