Yes, it's a maple. Two trunks don't preclude that. It's a consequence of something affecting the growing tip in its youth. Also young trees often colour later than mature ones. But I can't help you with the species or cultivar.

Based on what I can see of leaf shape as well the color of new growth, if you are in the eastern half of the US it is most likely a red maple, Acer rubrum.

im interested in where the tree is ....

there is no indication of any fall color on any plant in the garden ... im wondering why you expect this tree to be in fall color ... ??? .. unless the pix are mid summer pix????

ken

ps: thats some nice edging .... but if you just built the bed.. and the tree is a recent planting ... that could be a reason for it being out of phase.. with reality ... lol ... ive had a few trees.. take a couple years to settle down and actually properly color ... according to specs ... autumn purple ash comes to mind ... before eab struck ...

Yes, it is definitely a maple. It is still in active growth so it wouldn't be turning yet.
