Small, green/purple flowers appear in clusters in the spring and winged seeds, as shown, mature in late summer. It is the host plant for the Eastern Tiger Swallowtail butterfly and currently threatened by the invasive Emerald Ash Borer. For more information, visit:

White birch trees are easily detectable due to their distinctive white flaking bark that resembles paper. In the spring, these trees produce catkins (top image) which allow for wind pollination when they mature and drop off the tree. To learn more about white birch trees, visit:
