Enigmatic Acer cappadocicum
Acer cappadocicum ‘Aureum’ (Acc. # 442-36*B), with its blond canopy rising above others in the maple collection, catches your eye as you stroll down Bussey Hill Road and look across the rosaceous collection. This curious tree, a cultivar of Coliseum Maple accessioned in 1936, has been experiencing rather dramatic summer leaf bleaching for the past several years, with many leaves in the upper canopy turning stark white and dropping from the tree. Multiple causes have been hypothesized, from a somatic mutation in part of the crown to innate susceptibility of the cultivar due to insufficient photo-protective pigments. Join Putnam fellow Chase Mason to hear results of a phytochemical investigation of potential causes of this phenomenon. To appreciate the canopy, gather by Carefree Beauty™ Rose (Acc. # 407-97*MASS) at the intersection of Forest Hills, Bussey Hill, and Meadow Roads on Thursday, July 14 at 6:00pm.

Parking: Park along the Arborway and enter at the Arborway or Forest Hills Gates. Walk to the ponds to view the tree from across the Bradley Rosaceous Collection.
Public Transportation: Take the T to Forest Hills. Exit the upper level of the station and cross South Street. Turn right on South Street and head uphill, parallel to the exit ramp, to the Forest Hills Gate. Enter the Arboretum via the Forest Hills Gate and walk along the roadway toward the ponds to view the tree from across the Bradley Rosaceous Collection.
