Just gone down the wormhole of apples whilst trying to read about Granny Smith.
So an apple seed does not grow the same variety of the one it came from.
It is a genetic lottery and you could get any type of apple. A new amazing variety or a hard sour apple.
So how do they keep making Granny Smiths? Well it’s a clone of the first ever Granny Smith tree. They use clippings and attach that to another tree. So there is no actual Granny Smith tree!
It’s really fascinating when you search how all these apples were discovered.
For example how Pink Lady got trademarked and How you have to be part of a club to grow the Jazz Apple.
