I found this interesting for two reasons Norm.
First, the rhythm - it has a distinctly regular and, I assume, intentional cadence until the last stanza (which is also indented), that caught my attention, and made me want to re-read, to see if the conclusion would cast a different, or undiscovered perspective on the whole.
Second, the title - which in retrospect, had an effect on me. The stereotypical impression of 'boys in trees' is possibly one of 'action' - maybe something like 'boys will be boisterous', whereas this has an atmosphere redolent of sensitivity, the sensory experience, and in part it's almost sensual - well, to my ears anyway :>

Beautiful imagery and it has a lilting music due to the
alliteration and internal rhyme. I found myself replacing
"first" in the last line with "early" - I think because of
iambic consistency (but I can see the connection with Eden
and "first"). I like the constrained Romanticism in this
appealing lyric...BRgds.,Alan.
