I am having problems growing my cave beans as they keep getting eaten, I have tried netting etc but still they are eatenI need some pictures of their flowers for my painting and although looked on ...

We are sorry to hear something is nibbling away at your beans!  The flowers are normally white, we've found a link to a US company that sells these rare seeds and you can just see the flowers on one of their images:
