Two Mysterious Pomegranate Trees

Hunan First Normal University (湖南第一师范学院), is a popular site for red tourism on account of its association with Mao Zedong. One point of interest is a well where it is said Mao used to draw cold water to wash himself. More interesting to me is beside the well are two pomegranate trees (punica granatum, 石榴 ) that were damaged (parts of are still visibly scorched) but not destroyed by the 1938 Changsha fire. Ever since the fire, one of the trees flowers but does not bear fruit; the other tree bears fruit but never flowers.
