A pluot is a hybrid fruit created by cross-breeding a plum and an apricot. Pluots do not occur in nature and were first created in the late 20th century.
The composition of a pluot is roughly 60 to 75 percent plum and 25 to 40 percent apricot. They thus taste more like a plum but have the texture of an apricot. They also usually have the plum's darker coloration.
The pluot was created by Floyd Zaiger in the 1980s and is a registered trademark of his company, Zaiger Genetics. There are actually over 20 varieties of pluot, which vary in how much of the composition is plum and how much is apricot.
