The Kentucky Coffeetree is a slow to medium-growing species that is native to the midwest; it was Kentucky's state tree for nearly 20 years, hence providing the first part of this organism's name. While the second part of this tree's name (coffee) may seem inviting to taste this plant, it is important not to eat this plant raw, as the seeds and pods are poisonous to humans because they contain cytosine. However, upon roasting them, one can use the leaves, seeds, and pulp of the Kentucky Coffeetree to make beverages similar to coffee. This tree is remarkable in its toughness and adaptability; it can survive both droughts and floods, as well as high levels of air pollution. The Kentucky Coffeetree makes a great ornamental tree (as seen on Yale's campus) due to its unique ascending branching structure, which gives the plant a crown-like appearance. Students can look forward to this striking view as May and June approach, as the Kentucky Coffeetree is known to bloom in late spring. On the topic of blooming, this species is deciduous; its leaves emerge in a beautiful bronze-pink shade and progress to dark green over time, then as fall comes, the leaves turn yellow and brown before falling from the tree.

The Eastern Redbud tree, also known as Cercis canadensis, is a small, deciduous tree that can be found in eastern North America. It is commonly found in wooded areas, along streams, and in parks and gardens. The tree grows to be 20-30 feet tall and has a rounded, spreading canopy that provides dappled shade. Its bark is dark brown and slightly rough, and its heart-shaped leaves are bright green in the spring and summer, turning yellow in the fall. One of the Eastern Redbud's most striking features is its pink to purple flowers, which appear in early spring before the leaves. These small, pea-like flowers bloom in clusters along the branches, making the tree look as though it is covered in pink or purple mist. After the flowers fade, the tree produces flat, brown seed pods that persist into the winter. The Eastern Redbud's wood is hard and dense, making it useful for woodworking projects. The tree is relatively low maintenance and can tolerate a wide range of soil types, as long as they are well-draining. It is also resistant to pests and diseases. Overall, the Eastern Redbud is a beautiful and versatile tree that adds color and interest to any landscape.

A message from our English ivy specimen growing up a wall and neighboring tree along the Farmington Canal Trail behind Pauli Murray: "Ivy is one of those plants everyone knows, and comes with a lot of baggage..." well excuse me, don't we all?! I may be getting dragged on the daily for "dominating the canopy," "invading California and the northwestern United States," having fruits that are "toxic to humans and livestock," or being "very costly and labor intensive to eradicate," but the haters only make me stronger. And I didn't hear a peep from them when I was out here purifying their air, making the front of their house all green and trendy, or providing shelter for adorable birds and bats. Long story short, it's tough being famous. I came here all the way from Europe and Africa, so love me or hate me...plant me or spend thousands of dollars and countless Saturdays trying to remove me...I'm not going anywhere anytime soon. ;) With love and ground cover from your favorite woody, perennial vine, English Ivy P.S. Please do not group me together with my sister Poison. We don't know where she went wrong...
