Melon Seeds

Melon seeds will grow Melons in 1.8.

Over time, Melon Seeds will grow into the maximum size and grow a Melon on any adjacent Farmland block. If one of the adjacent Farmland blocks has a Melon on it, the seed will not grow any more Melons until the Melon is removed. A single seed can grow an infinite amount of Melons.

Melon seeds can be found in Abandoned Mine Shaft Chests or crafted from a single melon slice.

Crafting
Melon seeds can be crafted out of 1 Melon (Slice).
