F. Otto Haas Oak Allée

This European style lane was first planted in 1905 as the entrance drive to the estate from Hillcrest Avenue. Eighty-six scarlet oaks were originally planted, but the venerable allée was destroyed in a 1991 tornado. Replanted in 1992 with Shumard oak, oakleaf hydrangea, bottlebrush buckeye, and deciduous hollies, this area has a seasonal interest throughout the year. Allées were originally introduced as a landscape feature during the Italian Renaissance. The word “Allée” is from Old French, aller meaning “to go” and refers to a walkway or drive bordered by rows of evenly spaced, even-aged trees of the same species. Allées were popular in European royal parks and estates in the 17th and 18th centuries mostly in France and England. In the late 19th century in America, it became popular to create tree-lined streets on the model of the allées.

Construction Notice:

Parking Lot Closed September 21, 22 and 23.

Morris Arboretum’s parking lot is being repaved September 21, 22 and 23. Our parking lot is a demonstration lot for its sustainability. Installed 25 years ago as one of the first of its kind, the parking lot has filtered into the earth about 31,863,304 gallons of precipitation from the Wissahickon watershed. But the time has come for it to be renewed.

The entire parking lot will be closed September 21, 22 and 23. Auxiliary parking will be available at the bottom of the hill (near the kiosk) and shuttle service will be provided to the top of the hill. ADA access will be limited. No buses will be permitted beyond the kiosk.

We apologize for the inconvenience, but we are committed to keeping our parking lot sustainable and our visitors safe. Thanks for your patience.
