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."
4. If you have an actual green thumb, it might be scurvy.
3. Lettuce is 96 percent water and 4 percent lettuce.
2. The White House tool shed contains shovels, trowels and Weed Whacker One.
1. With enough care and effort you can grow your own "Barack-oli." (This was accompanied by a prop stalk of broccoli bearing a keen resemblance to her husband, President Barack Obama.)
"Thank you very much, Mrs. Obama -- thanks for taking your time," Letterman told the first lady, who made her first appearance on his show this past March.
Michelle's new book, American Grown: The Story of the White House Kitchen Garden and Gardens Across America, is in stores now.
