Evans suggested that when they bump into each other, they do what friends often do after being apart for a while: assess each other’s haircuts. In some ways, they’ve swapped styles. Thor has gotten a clean-cut trim, while Cap is sporting the ragged locks and beard.
“I’ll be like, ‘Short hair now? Good choice,’” Evans says, while miming a right hook against an invisible Outrider.
“And I’ll go, ‘Yours too. The beard. Very rugged,’” Hemsworth says.

I feel like I scream this all the time. Thor speaks Groot. The language Groot. And he introduces his friend as Tree. His name is Tree, he is a Groot. He is a Groot named Tree in the MCU.
I read lots of comics but I haven’t stumbled across this character in my pull list yet, so I have no idea about his in comics.
But I believe he is a Groot named Tree.
