Juglans nigra

Eastern Black Walnut


Conestoga House & Gardens, 1608 Marietta Avenue, Lancaster PA


David Kantner


This specimen has a trunk circum- ference of 12 feet and thus is larger than the Black Walnut at Wheatland. The circumference of Valley Forge’s Pennsylvania State Champion, how-ever, is 18.5 feet.  So the Conestoga tree is of county, not state, signifi-cance


This amazing species has so much of the toxic chemical “juglone” in its nut husks that these were formerly used to poison fish until the abhorrent practice was made illegal.

Note:  Possible Pennsylvania penalties for the above crime include a base fine of $75-$250; additional fines of $20 per fish; and imprisonment of 20-90 days.
