I logged on purely by chance today and this was the first post I saw.
I grew the LabLab beans featured in the One Show programme, from bought seeds one of our Bangladeshi plot holders gave me. Unfortunately I didn't save any seeds because I told him he could pick whatever I grew - and he did! However, he is going to give me more seeds next year.
The plants produced lots of beans this year, they were quite thick but apart from having slightly stringy sides they were lovely.
