Answer:
What grows in winter, dies in summer, and grows roots upward?
I can sizzle like bacon, I am made with an egg. I have plenty of backbone, but lack a good leg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole.

Power enough to smash ships and crush roofs. Yet it still must fear the sun.
