Instead of asking to take a break under some trees while on a hike, you could use “boscage” to refer to the growth of trees. A landscape architect might use the same word to point out a grouping of shrubs. “Boscage” came into Middle English from the Old French “bosc,” meaning “forest”; that word was likely related to the Germanic word “busc,” also meaning “forest.” The Germanic root served as the origin for the English word “bush,” too.
