Ephemeral Phenomena: A Haiku

I could have written a hundred sentences about this topic. Instead, I have chosen to be parsimonious with words, and now I let you puzzle over the meaning of the haiku I have written instead:

Wizened old witness,

Of growing and withering,

Sheds her last leaves. Peace.
