Evergreen and Deciduous Tree IdentificationĪn evergreen tree is a tree that never drops its leaves or needles. tree diversity is much higher east of the Mississippi river compared to the West.Ī larch loses its needles in the fall. There are about a half dozen species of trees in that massive area! If you’re in Florida you’d better get to work because there are hundreds of species in that state. If you’re in mainland Alaska then your task as a tree identifier is pretty easy. This accounts for about 20% of all plant species on the planet. There are about 60,000 species of trees on Earth. Palm ‘trees’ and bamboo fall under the monocot category and therefore aren’t trees (you can still think of them as trees though, only snobby botanists will call you out on this). This means that monocots are never trees. Nature never fits perfectly in the boxes we prescribe to it.īotanically speaking, only dichotomous plants can produce wood. Rarely, some ‘bushes’ can reach up to 40 feet high. However, if the plant has many trunks coming from the ground and is less than 15 feet tall, it is a bush rather than a tree. Bushes, like trees, are also woody plants. The line between bush and tree can be blurry. Vines also aren’t trees (although some tree branches have vine-like habits).
This group includes herbaceous and perennial wildflowers. Let’s rule out some broad categories of plants that aren’t trees.Īny plants that die back to the ground in winter are never trees. The technical definition of a tree is a woody plant that has a single trunk that grows to a considerable height. Eucalyptus trees have interesting branching patterns and bark.
