So that's how Cavendish bananas got their name! I had no idea. Cool (or should that be warm?) fact of the day!
Also cool fact I just looked up after learning that - they were cultivated there by Sir Joseph Paxton, head gardener, designer of the Great Conservatory and later of the Crystal Palace!
Lots of neat associations with the name Cavendish. :)
And yes, OP, Puddy Cavendish does sound adorable, and has a very 1920s air.
