It might seem like Granny Smith apples have been around forever. When you think of a green apple, the classic taste and color of this variety is probably what comes to mind. However, the Granny Smith variety wasn’t introduced to the United States until the 1970s.

Believe it or not, Granny Smith apples were named after a real-life Granny Smith. Maria Smith lived in Australia in the late 1860s. An apple seedling sprouted from the pile where she disposed of the crab apples she used for baking. She’d never seen a seedling like this one, so she let it keep growing.

Once the Granny Smith seedling bore apples, the flavor and color impressed her.  She began selling the seeds to other local farmers. The apples became popular in Australia over the next fifty years and were introduced to the United Kingdom in the early 1930s. The apple was easy to grow, stored well, and could be used for almost anything.

In the 1970s, Granny Smith apples reached the United States and immediately became just as popular as it had been in Australia.
