Birches bend and shed their bark, but should they bend for me?

Thanks for the feedback, billy and toinfinity - it is appreciated very much.

I mix things up where rhyming is concerned. I don't follow rules very well, at least in my writing. 

impending / ending
in / kin
vast / tasks
adaptation / amalgamation
one / none

Does it read too awkwardly? I can make the rhyme scheme a bit more conventional.

Oh, and no - I didn't write the poem around the last line. It hadn't struck me until I got there, actually. That's one of the things I love so much about writing. If something is meant to be, it'll be!
