Syzygium pycnanthum is a member of family Myrtaceae or known as ‘Jambujambuan’ family. The research aim was to observe the development process of flowering and fruiting phase of S. pycnanthum at Purwodadi Botanical Garden. It has been noted that this species has ten (10) stages of flowering and fruit development, namely flower bud initiation, flower bud fully emerge, unfolding calyx, visible corolla, bud starts blooming, early blooming, perfectly blooming, perianths and anthers fall, early fruit structure and ripe fruit. All these stages require 80-89 days.
