Planting seeds in her husband's re-election bid, Michelle Obama delivered a Top 10 list of gardening-related tidbits on Late Show with David Letterman Tuesday.
The first lady, clad in a resplendent yellow dress, delivered the list from the map room of the White House, in promotion of her new book, American Grown: The Story of the White House Kitchen Garden and Gardens Across America.
And now, for the list …
10. Gardening was invented in 1822 by Albert Gardener.
9. Plant avocados, tomatoes, onions and cilantro together and grow a guacamole tree.
8. Eggplants were originally cultivated for use as doorstops.
7. In his lifetime, the average American will eat half a radish.
6. The largest zucchini ever grown contained a Starbucks.
5. Later this year the Supreme Court will finally rule on "tomato" vs. "tomahto."
