They actually were a whole different species: yew trees. I realized that they were not pine trees at all. I used to think these small, stubby, shrub-looking trees were baby pine trees, and that their needles would grow long and thin one day. Be careful when you touch them - you might get pine sap on your fingers which, although it smells amazing, will take forever to wash off. Pine trees are evergreen conifer trees, meaning that they are green all year round and bear cones instead of fruit. Pine “leaves” are actually thin needles that grow in little bunches. Cherry blossom tree leaves look very similar to elm leaves the way you can tell them apart is subtle, but you’ll see that elm leaves have more defined teeth, and are tougher than cherry blossom leaves, which are more fragile and thin. They also have a pointy tip, making the oval shape more like a teardrop. These leaves are also toothed, meaning they have jagged points all around the edges, like little teeth. In most cases, you should be able to fold a maple leaf in half down from its stem to the tip, and have both sides align perfectly.Ĭherry blossom trees, also known as sakura trees, have oval shaped leaves. The maple family falls under the genus Acer, which means “sharp” in Latin. The maple leaf, featured on the Canadian flag, is pointy and symmetrical. The picture above shows round lobed oak leaves, meaning the tree is a white oak. Red and white oaks are just different species of oak, and two of the most common ones. The difference between round and pointed is that round lobed leaves mean that the oak is a white oak, and pointed leaves mean the oak is a red oak. They have rounded or pointed “knobs” around the leaf. Oak leaves are easily identifiable because of their lobed leaves.

These teeth often have one to four glands. Taking a closer look at the leaflet's shape will prevent confusing Ailanthus with black walnut ( Juglans nigra). The leaflets have an unequal base with two to four teeth. The pointed shape helps to differentiate tree-of-heaven from other trees that grow in our area that also have compound leaves. In this case, the compound leaves have 11 or more pointed leaflets. The leaves can grow to be one to three-feet long and are compound, meaning that each leaf consists of a number of leaflets.
