Yes it's very old fashioned and probably not really worth eating.
But they are charging £1 in the local supermarket for a small black punnet!!!!
We bought three packs of seeds for £1 from a well know discount store on Foss Islands Road in York (It might be called M&B?) The Coriander and Parslry are doing fine on our little balcony in boxes. But the star of the show has been the Radishes. They germinate within a day and grow incredibly fast.
So we had 3/4 of a packet of seeds left. We popped a bit of kitchen paper in a pot and now we have lots of little friends to eat!
