Maple Grove Park, 1420 Columbia Avenue, Lancaster PA
White Mulberry rarely lives beyond 75 years; most trees die before 50. However, a tree that George Washington planted on February 28, 1785 (according to his diary) still lives 233 years later [see photo at left]. While it’s hard to be precise, the mulberry at Maple Grove is surely one of the oldest in Lancaster County.
Almost all of the Morus alba growing in Lancaster County today are thought to be offspring of trees planted early last century to feed silkworms, thus supporting the silk industry (see 'Special Topics'). This Maple Grove tree, for example, may have sprouted from the droppings of some long-ago bird who feasted on the fruit of a local mulberry orchard.
This amazing species releases pollen from its catkins at approximately 350 mph, over half the speed of sound, making it the fastest known movement in the plant kingdom.
