I have 3 dianthus furcatus plants grown from seed from the 2018 seed exchange. The leaves all look similar but there are 3 flower forms. Are all 3 dianthus furcatus? I also have a dianthus alpinus grown from seed that looks similar to the paler form in the photo with the 2 colour forms.
I'm really pleased with them - thank you!

Hi,
The third may be D. furcatus but further pictures would be needed (close up of the flower up and side to see if there's some hair on petals, and the shape of the calyx)
The two first are not furcatus
You can look at pictures from the wild here : https://www.florealpes.com/fiche_dianthusfurcatus.php

Hi Dewberry,
Not familiar with furcatus but based on Yvain's link I would be rather doubtful that any of your plants are this species. The first two look rather like D. alpinus (especially the darker one - not so sure about the paler one).
Best wishes, Tristan

There are hairs on the upper side of the petals (top picture).

furcatus is usually hairless, has pale pink flower and epicalyx shorther ~half of calyx.
About hair on petal, flora europaeae give the 2 possibiliies but FLora gallica give only one (hairless). You can have lots of pictures of this dianthus here : http://www.photoflora.fr/FiTax.php?NumTaxon=2053
Identification of dianthus is not easy in nature even if you know which one you can encounter. In a garden, from seeds from cultivated plants, and without the natural localisation of the plant, it's nearly impossible as they are easily hybridising (I have hybrid carthusianorum x monspelliensis and requieni pseudocollinus x ?? that grow sponteanously in the garden...).
