I read somewhere that the F1 hybrid Peer Gynt (i think) won't have its position renewed on the national seed list, so maybe this year would be the last year to be able to obtain seed for it.
Another old sprout is Bedford(-Fillbasket) which is a standard open pollinated variety.
I grew red delicious last year (first time for brussels) and they were tasty. We still had to buy green brussels for Xmas which were shredded, along with the red, and stir-fried to make a colourful dish. This year, I am growing another two organic varieties (De Rosny and Wellington) so we shall see how that goes....
