Specimens of Note

Beside Oakwell Mansion, we have a white oak that has been growing since the birth of our nation. The Lenape call this tree wipunkòkw and the scientific name is Quercus alba. This is the very white oak to which Olmsted referred in his telegram to William Bodine. ​This In 1919, when distinguished WWI veteran William Bodine was deciding where to place the new home for his young family amongst the forested corner of the Bodine’s Stoneleigh estate, he placed it between multiple oak trees that formed a continuous canopy shading the Oakwell home, their roots intertwined throughout the property, anchoring the soil and communicating through their fungi networks. Deciduous trees planted on the south-facing side of the residence would have allowed for light to warm the house in winter and shade the house in summer. This white oak is one of four that were originally formed a continuous canopy that continued east of the mansion. One of them was struck by lightning around 2012.

Circumference: 13.28' = 159" (50.5" diameter)

Height: 95'

Spread: 107' widest, 97' narrowest = 102' average spread

Behind the mansion, against the driveway and almost on the north property, is the 3rd largest tuliptree in Montgomery County. In the Lenape language this tree is called mùxulhemënshi, which means “canoe making tree”, and its scientific name is Liriodendron tulipifera.

Circumference: 13.45’ = 161" (51.25" diameter)

Height: 108’

Spread: 69' widest, 58' narrowest = 63.5' average spread

The second largest white ash in Montgomery County on the north property line. In the Lenape language, the ash tree is called mixakanakw and its scientific name is Fraxinus americana. Various calculators estimate that a white ash with a diameter this wide is approximately 300 years old.

Circumference: 15.6’ = 187" (59.5" diameter)

Height: 107’

Spread: 93' widest, 75' narrowest = 84' average spread

Toward the rear of the property, hidden behind multiple towering white oaks, you will eventually reach the largest red oak in Montgomery County, the "County Champion" located at the back right corner of the greenhouse complex. In the Lenape language, the red oak is wisahkakw, and its scientific name is Quercus rubra. This particularly magnificent red oak is one of the newly registered listings of the Pennsylvania Forestry Association’s PA Champion Tree Program. 

Circumference: 17.13' = 206" (65.5" diameter)

Height: 115’

Spread: 93' widest, 78' narrowest = 85.5' average spread
