In other words, every twig grows in a pair. Trees with opposite branching have two twigs growing across from each other. The American elm tree is just one of many tree species with alternate branching. With alternate branching, only one twig grows at each node on a branch, and the twigs alternate! On most trees, branches and twigs grow in an alternate or opposite pattern: Alternate Branching Some trees even have whorled branching (right), in which three or more twigs come out of the same place on the branch. In an alternate pattern (left), the twigs are staggered along each side of the branch in an opposite pattern (center), the twigs are directly across from each other on each side of the branch. Knowing these patterns can be a valuable tool in tree identification. The look of the branches provide additional ways to identify certain trees. Branches and twigs of trees grow in specific patterns. Many species have buds that are about an inch long and extremely pointed. Ash TreesĪsh trees are easy to identify due to their large, dark dome-shaped buds.Įach branch has a large singular bud at the very tip. Gingko buds grow directly on top of the remains of last year's leaf buds, slowly building these stubs over time. While often recognized by their triangular leaves or smelly berries, ginkgo trees also have buds with a distinctive knobby appearance. Some tree buds are more distinct than others: Ginkgo Trees Buds can be found at the tip and along the sides of smaller branches and twigs on a tree. They are covered by leathery scales that protect these young leaves until they are ready to really start growing the next year. Budsīuds aren’t just the people you look at trees with, they’re also another way to figure what trees you’re looking at! At the end of the summer, trees grow miniaturized versions of next year's leaves, called buds. These trees can be spotted in garden plantings inside Central Park, McCarren Park, Hudson River Park, and Rockaway Beach. This patchwork appearance happens as the tree grows and sheds bark from previous years. Crepe Myrtle TreesĬrepe myrtle trees have multiple trunks covered in shades of cream, peach, and cinnamon. Like many trees, cherry bark can also change with age, going from relatively smooth to a ridged or fissured appearance. These lines, called lenticels, allow the tree to exchange oxygen created through photosynthesis with carbon dioxide and water vapor from the air. But to make sure our trees stay healthy, please leave the bark on our birch trees! Cherry TreesĮven without its famous white and pink flowers, you can still spot a cherry tree by its dark bark dotted with horizontal lines. These sheets can be used for paper, baskets, building, and fire-making. In certain types of birch, the bark peels away in horizontal sheets. The bark of birch trees is often white, flat, and smooth. Paper Birch TreesĪnother bark that’s easy to spot is birch bark! The bark not only gives the London planetree a striking appearance, but also aids the tree in shedding pollution absorbed from the air. The London planetree, the most common street tree in New York City, also has some of the most distinctive bark - a camouflage of green, yellow, white, and brown. Let’s take a look at some of the most distinctive barks in New York City: London Planetrees Looking at a tree’s bark can help you identify tree species at any time of year! And the bark can come in a variety of colors, like brown, white, and even green. But unlike our skin, bark is actually made of dead cells, meaning it can’t expand much, so you’ll see cracks form as the tree grows. These cracks look different depending on the type of tree and environment. The outermost layer of bark protects these living tissues, much like our skin protects our bodies. Inside a tree’s trunk, its tissues move water and nutrients between the roots and leaves. Generally, you can look for these four features of a tree to identify its species: Bark And you can even use these clues in the winter, when trees usually go dormant and lose their leaves! Ever wanted to get to know the trees in NYC a little better? Most people only look at a tree’s leaves to try to identify it, but there are plenty of trees in the city that are easy to recognize just by looking at their bark, buds, and branches.
