The juniper in the linked example above (hope you visited it?) doesn't simply flag. It flows and undulates, and you can see the shapes of the curves in its trunk seem to follow arcs and ellipses.
To model this growth pattern, I used an ellipse (A) as the basis of a study and developed it the pattern of a tree growing in nature. I've cut it down to a portion (B) and iterated that segment several times (C) to produce the final sketch (D).
Here we have a trunk that is wind influenced, actively resisting and responding to the wind's activity.
