Hi,
The plant in the photo isn't Dianthus alpinus, which is a short-stemmed alpine with flowers characterized by white speckles (as shown in the other photo at this site by Ghislain118).
The site where the photo is from claims it to be Dianthus x allwoodii (though it doesn't actually list the name correctly); the plant does appear to be typical of Dianthus x allwoodii.
Could you please ask to have the photo moved to Dianthus x allwoodii?

Thanks,

We have no entry for D. x allwoodii. Dianthus allwoodii (with or without the x) is not recognized as an accepted species name in any of the major taxonomic databases. Neither is Dianthus alwoodii, as it's spelled on the Outsidepride site. I'll move the photo to the general entry for Dianthus.

That's fine. I am very puzzled though. D. x allwoodii is the name for a group of D. plumarius x caryophyllus hybrids, and I'd have thought that name would fit the rules for hybrids used by this site, as you've explained them to me previously.
Thanks,

I found it listed in the GRIN database, but that information was dated 2007, and the more recent database updates have eliminated it, so I guess it didn't fit their rules.
