the tree that flashes silver every time the wind has second thoughts

means A small to medium tree of the rowan family (Sorbus aria and relatives), native to Europe, with leaves that are dark green on top and densely white-felted underneath, so they shimmer pale when the wind turns them.

from A plain English compound: "white" plus "beam," where "beam" is the old word for a tree (Old English bēam, a cousin of German Baum, "tree"). So a whitebeam is simply a "white tree" — named for the silvery undersides of its leaves. That same old "beam"-as-tree survives hidden in "hornbeam" and in "beam" itself, since timber for a roof began life as a tree.
