Tree of the Week: Black Hickory (Carya texana)


Our tree of the week is a 25-year-old black hickory (Carya texana). Last year at this time, this same tree was featured as our tree of the week. You can find that post here. This year, we have a few more photographs, snapped under a sunny sky, allowing us to appreciate the striking fall coloration of this species.

 

Our tree of the week is located in the center of the arboretum, near the basement entrance to the Student Union Building. It grows in full sun at the top of a gradual slope.

With the sun hitting its leaves, our black hickory shows varying shades of gold, bronze, yellow and orange. In the photo above, sunrays directly hit the left (southern) side of the tree, resulting in bright yellow leaves. Dark orange leaves appear on the right (northern) side of the tree.


From another angle, we can appreciate the pleasant pyramidal form of the black hickory.

The clear blue sky contrasts with the yellow-orange triangular apex of the black hickory. The effect is similar to that of the Great Pyramid at Giza,the apex of which was originally plated with gold to catch the sun's fire. The hickory certainly achieves its beauty with much less work.
