Welcome to A4A
Regarding;
if you're interested in growing unusual veg
I thought Dawn would have mentioned her famous 'Killer Whale beans'.
Having grown some of them, my advice is keep them to 'Wee Willie' size when they get really big they go the same way as most overgrown beans, tough & stringy.
'Wee Willie'
take from that what you will ;)
