I’ve decided to split my exploration of Chestnut street into two sections: West of 15th and East of 15th.  I have documented a few tree species from each side.  Here are the first two trees, traveling West on Chestnut from 15th:

Pin Oak (Quercus palustris)

The Pin Oak tree species is hardy to zone 4 and is found primarily in the northeastern and north-central United States.  The tree is a large, deciduous tree which can grow to 75’ tall and 40’ wide at its max width.  The trees are pyramidal in shape when they are young and become an oval, tear-like shape as they get older.  They have a unique branding pattern, with lower and middle branches pendulous and horizontal, while the upper branches are upright and spreading.  Their canopies are very dense and full of twigs.  In the summer, their alternate leaf arrangements feature a shiny green color with sharply pointed lobes adorning them.  The leaves grow anywhere from 3”-6” in length and are fine textured.  In the autumn months, the leaves turn to a red and bronze color.  However, some urban trees can become brown or tan and are not as interesting.  The twigs also feature acorns that show themselves in the summer and fall months.  The main trunk of the tree has very noticeable shallow ridges and furrows and the color is gray brown, with smoother bark on the higher up, medium sized branches, with greenish brown stems coming from them.  The trees are easily transplanted and great shade trees.  They are some of the fastest growing of the oak species, however they need adequate room to successfully develop and aren’t really the best suited for city limitations.  Interestingly enough, here they are, adorning the sides of Chestnut Street…with barely any room to develop…   

Sawtooth Oak (Quercus acutissima)

Another interesting find here in the city was the Sawtooth Oak.  This type of Oak is native to Japan, China, Korea, and the Himilayas, and is hardy to Zone 6.  Like most oaks, the trees reach to a height of 40’-60’ tall, with a dense, rounded crown that is rather wide-spread.  The trees have a moderate growth rate.  The leaves are laid out alternately, and are simple, deciduous leaves in an oblong shape.  They grow to be 4”-7” in length and up to 3” wide.  They have serrated leaf margins, with bristle-like teeth on the serrations (see the images below).  The leaves are a dark, glossy green color in the summer and change to a brownish-yellow color during autumn.  The flowers are monoecious, and begin blooming in May.  During the autumn months, they fall to the ground and can become rather messy, creating interesting conditions along roadways within the city.  The bark is ridged and furrowed, and is a light brown color, with grayish twigs coming from it.  The trees are easily transplanted and are great city trees for the shade they provide as well as their ability to adapt to various conditions.  However, they do prefer well-drained soil, which can become a problem in urban conditions.
