This species, one of the most popular garden magnolias, is a hybrid that dates from the 19th century. Magnolias however are among the most ancient flowering plants — dating back to the Tertiary period, 100 million years ago. We are most familiar with the petals of flowers, but to me the really fascinating forms are the reproductive structures hidden in the center.
