The Sugar Maple is primarily used for maple syrup production; a single tree can produce 5-60 liters of sap per year! It is also known for its brightly colored Autumn foliage, ranging from bright yellow to orange or even fluorescent red. The tree is long-lived, typically reaching ages between 200 and 300 years and can grow to be between 50-130 feet in height.
