With a trunk circumference of 208 inches in 2009, a height of 84.6 feet, and a spread of 110 feet (pabigtrees.com<\/a>), this tree is among the top three largest White Oaks in Lancaster County, and among the top 30 White Oaks in Pennsylvania.  <\/p>\n\n\n\n

\u200b”The Penn Hill Oak was a young tree when the Quaker meeting house was built around 1750,” Mary Boomsma said. “I’ve heard it was there before William Penn was given Pennsylvania.”<\/p>\n\n\n\n

The ISA formula for inferring the age of trees (see Special Topics:  Estimating the Age of Trees)<\/em> produces a figure of 331 years using the 2009 measurements; up- dating to 2018 brings the estimate to 340. Thus Boomsma’s statement is plausible: This White Oak may indeed be a Penn Tree.<\/em>   (King Charles II of England granted William Penn the lands of Pennsylvania in 1681, 327 years ago.)   <\/p>\n\n\n\n

This amazing species has an unusual tolerance for growing near Black Walnut trees whose roots exude a natural herbicide\u00a0<\/em>(juglone)\u00a0that severely retards the growth of other plants.<\/em><\/p>\n\n\n\n
