description
The fire maple is a small tree or shrub that seldom reaches a height of 3 to 5 meters even up to 15 meters. It grows loosely upright with spreading main branches and mostly thinner branches. It often grows with multiple stems. The bark of the branches is red-brown on the sunny side, and from the second year it turns light brown and later gray.
The leaves shoot light yellow in spring and often red in summer. The opposite leaves are divided into petiole and leaf blade. The leaf blade is 6 to 10 centimeters long, 4 to 6 centimeters, broadly elliptical-elongated and three- to five-lobed. The middle lobe is the longest; the edges of the lobes are sawn. The leaf tops are glossy dark green, the undersides light green. The autumn color is bright red and sets in early.
The approximately 6 cm large, bare, upright, umbrella- clustered inflorescence contains around 50 flowers. The white-yellow flowers are fragrant.
The nut fruit is 2.5 to 3 cm long with the bald, translucent wing. They are at an acute angle to parallel to each other.
The number of chromosomes is 2n = 26.
