Syzygium aromaticum (Clove) is a triangular-shaped evergreen tree growing about 12 m
tall with a smooth grey bark and about 12 cm long, glossy opposite leaves that resemble
bay leaves. The attractive red and white bell-shaped flowers have four tiny petals
surrounded by a long, four- parted calyx and numerous stamens. The clove buds, shown
in Figure 6a and Figure 6b, are pink but calyx changes from yellow to deep red after the
stamens fall. The fruit, called mother of cloves, is an edible purple berry about 2.5 cm
long. The entire Syzygium aromaticum plant is extremely aromatic
