This blossoming crab apple tree is the main character of Berkeley College's North Court. Malus trees are a group of 42-55 small, deciduous trees or shrubs that grow 4-12 meters in height. Malus trees are native to the temperate zone of the Northern Hemisphere. Malus trees are often self-sterile which means that cross-pollinators like bees are recruited to spread pollen from the stamen of one Malus flower to the stigma of another Malus flower. However, it is common that Malus species freely hybridize, which can make it difficult to categorize a unidentified Malus tree based solely on its physical characteristics.

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.

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.
