The American Elm is a tree with a sad but hopeful story. Once, these trees lined streets all over America. They were big and beautiful, with branches that spread out like an umbrella.
But in the 1900s, a disease called Dutch elm disease killed many of these trees. It was a tough time for the American Elm. However, some trees survived and scientists are working hard to bring them back.
American Elms can grow very tall – up to 100 feet! They have dark green leaves that turn yellow in fall. The leaves are oval-shaped and have jagged edges.
These trees are tough. They can grow in many types of soil and can handle cold weather well. That’s why they were so popular for planting in cities.
The wood of the American Elm is strong and flexible. People used it to make furniture, floors, and even boats. Native Americans used the bark to make canoes.
Today, you can still find American Elms in some places. Scientists are breeding new types that can fight off the disease. Maybe one day, these trees will line our streets again.

The Siberian Elm is a tough tree that can grow almost anywhere. It comes from Asia, but now you can find it in many parts of the world.
This tree grows fast and can live in hard conditions. It doesn’t need much water and can handle very cold weather. That’s why it’s called Siberian – it can grow in cold places like Siberia.
Siberian Elms are usually about 50-70 feet tall. They have small, dark green leaves that are oval-shaped with jagged edges. In spring, the tree gets tiny flowers before the leaves come out.
People have planted Siberian Elms in many places because they grow so easily. They’re good for making windbreaks – lines of trees that block strong winds. The wood is also used for making furniture and sports equipment.
But there’s a problem. Siberian Elms can grow too well in some places. They can take over areas where other plants should grow. That’s why some people call it an invasive species.
These trees also drop a lot of seeds and branches. This can make a mess in yards and gardens. Some cities have stopped planting them because of these problems.
Despite these issues, Siberian Elms are still important in some places. In parts of Asia, people use the bark to make medicine.

Okay, this one is a bit different! Sea Lettuce isn’t actually a tree, but a type of seaweed. We’re including it because its scientific name starts with ‘U’ and it’s often called “sea lettuce trees” because of how it grows.
Sea Lettuce grows in oceans all over the world. It looks like bright green, thin sheets or leaves. These “leaves” can grow up to 40 cm long and are only two cells thick!
This seaweed grows attached to rocks or other hard surfaces in the ocean. It can grow very fast, sometimes doubling its size in just a few days.
Sea Lettuce is important for ocean ecosystems. Many sea animals eat it, including fish, crabs, and sea snails. It also provides shelter for small sea creatures.
People eat Sea Lettuce too! It’s used in salads and soups in some parts of the world. It’s healthy to eat because it has lots of vitamins and minerals.
Sometimes, Sea Lettuce can grow too much. When this happens, it can cause problems for other sea life. Scientists are studying ways to use this extra seaweed, like making it into biofuel.
