From the Top
Those uppermost branches, the ones that scrape the sky and soak up the sun, they are the first to bud. Everything else follows in kind.
It's an interesting phenomenon, metaphorically speaking (and — given that I've forgotten most of what I learned in Intro Biology — that's the only way I can speak). Flowers, plants, crop, they all grow from the ground up. But blooming starts at the top and works its way down.
There has to be message here somewhere.
