The northern red oak, Quercas rubra, is native to North America. The northern red oak can be found in forests throughout the Great Lakes region, Midwest, up to Nova Scotia, down to Mississipi, and all the way up to Maine. As the most common species of oak in the Northeast, one can expect to run into this majestic tree fairly often. The champion oak, as it is sometimes called, grows up to 43 m (141 feet) tall and can live up to 400 years. Its name is derived from the beautiful red foliage it displays in the fall.

My window looks right onto the fullest part of this tree and I have lived in rooms that surround this courtyard for most of my Yale Undergraduate time. It has been lovely to see it grow into the magnificent tree we see today.

The bur oak is a large deciduous tree that possesses alternately arranged simple leaves and a wide, uniform crown. Bur oaks are among the most fire-resistant, cold-tolerant, and drought-resistant of all oak species; thus, they are distributed over a wide geographical range in North America. The plant is monoecious with imperfect flowers, a quality that reduces the chances of self-pollination and is thus advantageous for promoting genetic diversity within the population. The lifespan of bur oaks generally exceeds 200-300 years.

Callery pear trees are very tall and beautiful. If you catch them in the springtime, they are covered in beautiful white flowers, and you can usually smell them from a block away as they produce a very strong odor. They bear fruit that is usually consumed by birds, not humans. This tree is known to be an invasive species. This tree not only serves as a decoration to whatever environment it may be in, but also as a shelter and food resource for birds.

People might think of their annual trip to pick out a Christmas Tree when they look at a Norway Spruce, and they are exactly right! The Norway Spruce is a large pyramidal tree that is dark green in color with long, cylindrical cones. Not only are they extremely popular for the holiday season, but they are also widely used for construction, pulp, furniture and musical instruments. Fun fact #1: The name of this tree is a bit of a misnomer. Although the species does grow in Norway, the Norway Spruce grew in Eurasia, the Black Forest and other parts of the continent long before making its way to Norway. Fun fact #2: The tree at the Rockefeller Center every year during the holidays is a Norway Spruce. Fun fact #3: The young branches in a Norway Spruce are often used to make beer.

The American Elm is a species native to the eastern part of North America. It is a large deciduous, hermaphroditic tree that produces small perfect flowers in early spring. The flowers are wind pollinated, however, since they are protogynous (the female organs maturing before the male organs) this greatly reduces the chances of self fertilization. These kinds of trees can grow to more than 100 feet and they often provide great shade with their umbrella-like canopy. You have probably passed by this specific tree if you have ever taken a stroll on the New Haven Green. Unsurprisingly, this is one of very many American Elms on the Green. Maybe that's why New Haven is called Elm City!

Loquats are evergreen trees that originated in China and grow in subtropical regions all over the world. The tree pictured is one of four loquat trees in my backyard and is approximately five years old. This tree accidentally grew in this spot because my dad threw the seeds into the grass here after eating a fruit from one of the other trees. The fruits that this tree produces are tangy and sweet, and its leaves make an aromatic tea.
