The ash tree is a type of deciduous tree belonging to the genus Fraxinus. It is known for its tall stature, typically reaching heights of 30 to 80 feet. Ash trees have compound leaves, which means each leaf is made up of several smaller leaflets. They produce small flowers in the spring, followed by clusters of winged seeds called samaras. Ash trees are commonly found in North America, Europe, and Asia, thriving in a variety of soil types. They are valued for their strong, flexible wood, often used in furniture and sports equipment. However, many ash trees are threatened by the invasive emerald ash borer, a beetle that damages the tree's health.
