We have corn cockle, corn marigold, corn poppy, corn flower and something else corn ;D
Our aim is to strim the grass around the perimeter fence and grow them there, would they be better in patches, it would be easier to take up the grass. I think, as far as the RHS is concerned, it's to mark the queen's jubilee for this year only :)
Not really feasible to grow them on as plugs as it would be me doing it :-\
