Flower pots and windowsills seem to have a natural affinity for each other. It takes planning to grow pots of colorful blossoms, however. As a shortcut, arrange cut tulips, lamb's ears, lilacs, or other flowers in glass vases or small jars placed inside the pots. Cut the stems just long enough so that the blossoms clear the rims of the pots and appear to be spilling out.
