Sycamores are among the last trees to go into leaf; in the fall, they are the first to shed. They make sweet food in green broad leaves for a while—leaves wide as plates—and then go wild and wave their long white arms. In ancient Rome men honored the sycamore—in the form of its cousin, the Oriental plane—by watering its roots with wine. Xerxes, I read, “halted his unwieldly army for days that he might contemplate to his satisfaction” the beauty of a single sycamore.
