The Ents/Onodrim and Groot are both walking, "talking" (quotes in terms of Groot) tree-like beings. Groot was first shown in Marvel comics in Tales to Astonish #13 (1960) and Tolkien published The Lord of the Rings on the 29 July 1954, 11 November 1954 and the 20 October 1955, with the Ents first appearing in The Two Towers (11 November 1954). There was therefore around 6 years between them. Also on the LOTR fandom Wiki page for the Ents it states "The Marvel character Groot bears many similarities to Ents".
Considering how The Lord of the Rings became so iconic in world literature, as well as the short space of time between its publication and the introduction of Groot, was the character of Groot inspired by the Ents and is there any input from Groot's creators about this?
