EXOCHORDA GRANDIFLORA (_syn Spiraea grandiflora_).--North China. This
handsome shrub forms a much branched, spreading bush, about 4 feet to 6
feet high, and flowers abundantly in May. The habit is similar to that
of a shrubby Spiraea, but the pure white flowers are as large as those
of some of the species of Cherry, and quite unlike those of any known
species of Spiraea. The flowers are liable to injury sometimes from late
spring frosts, but the plant itself is quite hardy. As a bush on the
lawn it is nevertheless highly ornamental and desirable.
