Falling leaves have no words. Blossom in Four Seasons is the first half of an Internet phrase meaning that flowers will bloom brilliantly but there will always be a day when they wither, and its next phrase is Falling Leaves Have No Words, which is meant to praise the efforts that grasses and trees usually make for this purpose. The four seasons refer to the four alternating seasons of the year, namely spring, summer, fall and winter, each of which lasts three months.
