Where: Maple Grove Arboretum
What: Red Oak leaves
So: This photograph shows a Red Oak tree which has some leaves that are mostly red, some which are red and green, and some leaves which are mostly green. The red leaves, rich with anthocyanin, are faced toward the area of the tree which gets the most sunlight, while the more green leaves are the ones which reside in more shade. Those green leaves get less sunlight, and therefore, have worse conditions to create the vibrant red color which you can see in some of the leaves.

Where: Maple Grove Arboretum
What: Sentry Linden tree
So: This tree appears to have suffered a wound as shown in the picture. This could have been caused by people or animals, but you can see the calluses and growth that occurred because of this wound.
