The Origin of Granny Smiths

Granny Smith apples originated in Australia, in a suburb of Sydney, in 1868, according to the Worcester Tree Initiative. The apples are named after Maria Ann "Granny" Smith, the woman who first grew them. They are the offspring of a French Crab apple tree and whatever tree happened to pollinate it, resulting in this unique species of apple.

Interestingly, you can't plant a seed from a Granny Smith apple or a French Crab apple and expect to grow the same type of tree. This is because the new tree won't be a clone of its mother tree's genes; it combines the genes of two parent trees and the result is a different type of tree altogether.

If you want to grow a Granny Smith apple tree, you need to grow it from the cutting of an existing Granny Smith apple tree. The Worcester Tree Initiative explains that all the Granny Smith apple trees have therefore been grown from cuttings that trace their history back to the original tree.
