The leaves are palmately lobed with three to five lobes, and the fall foliage displays shades of yellow and orange. Black Maples produce winged samaras as seeds.
Boxelder (Acer negundo)
Boxelder is a smaller maple tree, typically reaching heights of 30 to 50 feet. The bark is light gray and smooth, often displaying shallow grooves as the tree matures. The leaves of the Boxelder are compound and consist of three to seven leaflets. In the fall, the foliage can turn yellow or pale green before dropping. The seeds are winged samaras.
Japanese Maple (Acer palmatum)
Japanese Maples are known for their ornamental value with finely divided leaves that come in various shapes, including palmate, dissected, and linear. The bark can be smooth or fissured, and the tree generally reaches a height of 10 to 25 feet. There is a wide range of leaf colors, including red, green, purple, and variegated. Japanese Maples produce small winged samaras as their seeds.
Norway Maple (Acer platanoides)
The Norway Maple is a large tree with a rounded canopy that can reach heights of up to 100 feet. The bark is gray and grooved, forming a distinctive pattern. The leaves have five lobes and are dark green in color, turning yellow in the fall. Norway Maples produce paired winged samaras.
Red Maple (Acer rubrum)
The Red Maple is a medium to large-sized tree that can grow up to 90 feet tall. The bark is gray and smooth when the tree is young, but it becomes darker with furrows as it matures. The leaves are palmately lobed with three to five lobes. In the fall, the foliage transitions to vibrant shades of red and orange. Red Maples produce winged samaras as seeds.
Sugar Maple (Acer saccharum)
The Sugar Maple is a large tree that can reach heights of up to 100 feet. The bark is gray-brown and furrowed as the tree matures. The leaves have five lobes and are known for their vibrant fall colors, including shades of orange, yellow, and red. Sugar Maples produce winged samaras as seeds.
Silver Maple (Acer saccharinum)
The Silver Maple is a fast-growing tree that can reach heights of 50 to 80 feet. The bark is light gray and smooth when young, but it becomes rough and furrowed as the tree ages. The leaves are palmately lobed with five lobes, and the fall foliage can display shades of yellow and red. Silver Maples produce winged samaras as seeds.
