An elderly neighbour has just asked me to find out where I can get hold of these so he can plant them next year... I have looked online but not many sellers and not too much info either, anyone on here grown them, or know where I can buy some Dutch brown beans for growing? Linda

Their calabrese Lord produced huge heads. They charge P&P and Vat but otherwise seeds and service good. Once you grow them you can then keep the seeds and sown your own.
I grew them a couple of years ago. They ripened fully to the drying bean stage weeks before anything else, beginning of August in fact
and i'm growing them this year, partly to get fresh seed
you're welcome to some if you don't mind waiting
