Has anyone ever planted these and had a result? Ray has saved the seeds

Yes. They germinate readily, and grow fairly easily in a warm,
sunny place. They are thoroughly unexciting, unfortunately.
The mature plant looks like a gigantic brussel sprout, and I
doubt that they would crop even in your polytunnel.
