Water Apple Botanically known as Syzygium samarangense from Myrtaceae family. It is not actually an apple. It is a tropical fruit that grows in south-east Asia, including southern India, Indonesia and Malaysia. It is a medium size tree, can grow more than 8 meter in height if planted in ground. It is an evergreen plant with broad leaves.

The flowers are white to yellowish-white, with four petals and numerous stamens. The resulting fruit is a bell-shaped, edible berry with colors ranging from white, pale green, or green to red, purple, or crimson, to deep purple or even black. The fruit grows 4–6 centimetres long and has 4 fleshy calyx lobes at the tip. The skin is thin, and the flesh is white and spongy and fruits appear on nearly any point on the surface of the trunk and branches. When mature, the tree is considered a heavy bearer.

It does not taste like an apple, and it has neither the fragrance nor the density of an apple. It is comparable to the taste of a watermelon. Unlike either apple or watermelon, the wax apple's flesh has a very loose weave. The very middle holds a seed situated in a sort of cotton-candy-like mesh. This mesh is edible, but flavorless.
