Pioneers made cinnamon-brown and black dyes from a bark extract, and iron sulphate could be added to the tannin from red maple bark in order to make ink. [29] Red maple is a medium quality firewood, [30] possessing less heat energy, nominally 5.4 gigajoules per cubic metre (18.7 million British thermal units per cord) , than other hardwoods ...
They are dark green and hairless above, with a yellow-green and softly pubescent underside. In autumn, the leaves turn from a brilliant yellow to orange to deep red. The fruit is a paired brown samara, 2-2.5 cm long, maturing in autumn. [3] Acer leucoderme is often confused with Acer floridanum (Florida maple), but there are several differences.

The sugar maple is most easily identified by clear sap in the leaf petiole (the Norway maple has white sap), brown, sharp-tipped buds (the Norway maple has blunt, green or reddish-purple buds), and shaggy bark on older trees (the Norway maple bark has small grooves). Also, the leaf lobes of the sugar maple have a more triangular shape, in ...
The leaves turn golden yellow to red [4] in autumn (less reliably in warmer areas). In Texas, specimens do not color well if they have a heavy seed year. [5] The flowers appear with the leaves in mid spring; they are produced in corymbs of 5–15 together, each flower yellow-green, about 4–5 millimetres (3 ⁄ 16 – 3 ⁄ 16 in
Shoots are slender with smooth, hairless bark. [8] [9] Vine maple leaves are coarsely toothed and 3 to 14 cm (1 + 1 ⁄ 4 to 5 + 1 ⁄ 2 in) in length. They are palmately lobed with 7–11 lobes, the lobe-points forming a nearly circular pattern. In the autumn, the leaves turn bright yellow to orange red.
The leaves are 10–15 cm long and 6–12 cm broad, with three or five lobes, the basal lobes of five-lobed leaves being small; they have a serrated margin, conspicuous veining, and a reddish 4–8 cm petiole. They are matt to sub-shiny green in summer, turning to bright yellow, orange or red in the autumn.
