Scarlet maple: this maple is such a bright shade of red, I think someone told it a very naughty joke.

Acer rubrum or Red maple is a very common tree in North America. It grows up to 15m in height, and is grown for its good looks and colour. It has red flowers that grow in clusters, reddish stems and bright red autumn foliage. When it comes to soil, acer rubrum can thrive in almost any conditions. It is often found growing in swamps and also in very dry and poor soils. The leaves have three lobes and are slightly serrated. This tree is grown commercially both for the timber, and for maple syrup production. Acer rubrum is the state tree of Rhode Island.
