I recall seeing on Gardeners World a place in the Midlands where you could go and purchase unusual vegetable seeds that are no longer sold in the UK by becoming a member, but I can't remember the name of the place. Can anyone help?
Try Garden Organic at Ryton near Coventry. Used to be called Henry Doubleday and Ryton Organic Gardens. I think you become a member and can then access their heritage seeds.
That's fabulous, thank you so much that was exactly the place I was thinking of.
