The thing that strikes me as manque about it is that it fails to mention the act. You're trying to describe your father's unselfish act. He put the dream somewhere deep within himself, to mature at a later time.
After he has made that sacrifice, you might say the dream within him remains germinal; but this could be true of all dreams, regardless of their origin. The sacrificial act which you call attention to in the beginning is not represented in your simile. Who puts the seed into the peach? God? Your father is supposed to be the peach, right?
