bringing the fig tree onboard

Commenting on the words, “Vayita kerem…,” Rashi writes that Noach was able to plant a vineyard immediately after exiting the ark because he had brought grape vines and shoots from a fig tree onboard with him before the flood.  Since the text of the Torah only mentions Noach's planting a vineyard, why does Rashi need to mention anything about fig trees?

The Ne’os Desheh, the son of the Ishbitzer, explains that Noach’s spiritual reach exceeded his grasp.  Noach had been privileged to learn Torah, he was chosen to be the sole survivor of the flood, he was the recipient of a bris with Hashem symbolized by the rainbow, and he was the one whom Hashem selected to restart humanity with.  An impressive resume – one that led Noach to shoot for even greater things.  Noach thought that by restarting human history through him, the world could be wiped completely clean from the sin of Adam.  Noach is called “ish ha’adamah” – a man who aspired to bring tikun to the earth, which had been cursed after Adam’s sin.  The vineyard Noach intended to plant was the vineyard of, “Ki kerem Hashem Tzivakos Beis Yisrael” --  Noach thought that he could even the founding father of Klal Yisrael.

Yet as great as Noach was, he was not Avraham Avinu.  The leaves of the fig tree that Noach took with him are a metaphor for the sin of Adam.  It was the leaves of the fig tree that Adam used to try to cover himself after eating from the eitz hada’as.  Noach did not and could not rise above the defects and imperfections that were part of Adam haRishon’’s makeup.  Even as he entered the teivah, what was on his mind was not planning mankind's spiritual future, but rather the enjoyment of a good glass of wine, the pleasure of olam ha’zeh.
