The narrator's daughter calls her multiple times to see the daffodils before they are over, but bad weather delays the trip. When the narrator finally visits on a rainy day, her daughter drives her to see the flowers anyway. They come upon a garden of 50,000 daffodil bulbs planted in swirling patterns over 5 acres by a single woman, starting 35 years prior by planting just one bulb at a time each year. The experience teaches the narrator the "Daffodil Principle" of achieving great things through small, consistent efforts over time.
