A tidy riddle: something that lives in winter, dies in summer, and grows with its roots pointing up. Guessing the answer together is half the fun of reading it aloud.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Lives in winter,
Dies in summer,
And grows with its roots upward!
