Lychnis chalcedonica

I think I've got some of these in the garden ,are they the ones they call the Maltese cross Dawn ?

Yes Amy. They are Maltese Cross, I have pale pink ones too. I prob sent you the seed :)

I haven't a pink one Dawn but I have this colour , I'm surprised it's doing so well in my garden if they like the water ...

I grew them as they are damp lovers. I can send you seed of the pink one :)
