Plants in the revamped rock garden are coming into flower: Dianthus pavonius, D. weyrichii, D. anatolicus, D. squarrosus.
-
Very nice Ralph, I have D. pavonius coming from seed but I'm not expecting flowers this year.
My Dianthus are coming too:
[attachimg=1]
Dianthus superbus sp. or possibly a hybrid by the pond edge.
[attachimg=2]
'Whatfield Magenta' on top of the wall. It grows in about 3 inches of soil and is never watered or fed.
-
You grow D. superbus by water? I know its a sub alpine species, but do you find it needs or will tolerate plenty of moisture? I ask because mine in struggling in a hot sunny gravel bed.
-
Hi Ralph, It's by water but not a wet spot. The pond is made with a retaining wall on one side because we are on sloping ground. There is a liner to hold water, backfilled with some soil between it and the wall. This soil is very poor and dry so I grow things like Dianthus, Lotus corniculatus, Anthyllis etc.
I haven't found D. superbus particularly fussy with regard to moisture - it grows for me in normal garden conditions and also in a very dry spot on top of the wall next to the 'Whatfield Magenta'.
Not sure if that's much help, perhaps mine is a more vigorous form (or even a hybrid?)

I was looking at your beautiful white Dianthus clump Tristan, with the Anthyllis in the background and was thinking just the same - that it may be a hybrid. I'll post an image with the type Dianthus superbus; not a great picture, it's from a plant that struggled in a container for 2 years. It is indeed a species that prefers moist locations, as far as I've seen in the wild. Heavenly scented!
-
Hmm Gabriela, I thought that's what I received it as but maybe I am mistaken, or maybe it was mislabelled when I bought it. There are one or two imposter Dianthus doing the rounds through seed exchanges etc.
Anyway, it's a nice little pink, whatever it is! I'll post closeups of the flowers and foliage in case anyone can shed any light.
-
Tristan, I think Gabriela is right. I grow D. superbus (unfortunately no pics) but my plant looks like Gabriela's.
It is native to Northern Norway:

Thanks both. I will have to do some detective work...
-
Pleased with the way the Dianthus are performing in the revamped little rock garden: D. squarossus, D. spiculifolius, D. freynii. And some good old Devon Pinks in the gravel bed.
-
Some other dianthus
Dianthus deltoides
Dianthus pungens (end of blooming) from south-east of France
Dianthus saxicola (= Dianthus sylvestris), different color
-
Again, few dianthus... all wild collected from cutting.
Dianthus gyspergae (from Corsica)
Dianthus hyssopifolius
Dianthus seguieri pseudocollinus
Dianthus x saxatilis (= Dianthus hyssopifolius X Dianthus seguieri)
-
Two more
Dianthus carthusianorum
Dianthus sp. : if someone have an idea... I can post more picture.
-
D. seguiriana subsp. pseudocollina is lovely isn't it Yvain? We came across a lot of it in the Livradois-Forez a couple of years ago and collected a little seed. It has established well in the garden and I love the contrasting dark calyx. The only thing that would improve it is a decent scent!
-
Even crossed with D. hyssopifolius (which has a nice scent, you should try it), it still has no scent but a nice big flower (see D. x saxatilis).
-
Nice Dianthus collection Yvain!
-
And lots of seeds to come ;D
I miss Dianthus arrosti (from Corsica), Dianthus pavonius (from Alps) and Dianthus superbus (from SRGC, ex-Norway, Hoy ?)
-
Yvain, Dianthus gyspergae is a nice dianthus, you're showing a nice set here.
-

It also seems your collection lacks the beauty from the Carpathians - D. petraeus ;)
-
Merci Yann ;)
D. gyspergae come right from Calanques of Piana where it is endemic. I am quite happy that the two cuttings that I took has rooted.
-

Yes Gabriela, nearly as beautiful as D. hyssopifolius :P I nearly only have native Dianthus collected during my walks, but this is only a matter of occasion and I will accept the opportunity to welcome D. petraeus in my garden ;) ;D

D. hyssopifolius is my favourite from all that you showed Yvain, nearly as beautiful as petraeus :P
I have two small clumps that usually don't set too many seeds, but you may get lucky who knows ;), or you may have to wait until I go on the mountain again.

Dianthus 'Eileen Lever'. This is a smashing little thing from Aberconwy that I picked up last year, not quite at its best yet. They had it growing in tufa which I might try too with some cuttings.
-
Dianthus squarrosus and Dianthus spiculifolius.
-
Dianthus haematocalyx ssp. haematocalyx from Mount Olympus in north Greece. This is Dianthus haematocalyx ssp. pindicola. From Mount Smolikas in the Pindus Mountains. 1960 meters. Northwest Greece.
And over again Dianthus callizonus from the southern Caucasus.

Beautiful and I envy you for being able to buy such treasures.
I would like to mention though that Dianthus callizonus is an endemic species from Romania in Piatra Craiului Massif (Carpathian Mts.), no relation with the Caucasus.
-
Dianthus callizonus is a favorite for me. I have grown many....

You are right of course completely, Gabriela... I has prescribed me. Thanks for the correction. But the first letter was right. ;D ;D Sorry for the mistake... Maybe because of the heat. 8) At other place I have already shown a photo, there I have properly described it. In the picture from yesterday one sees the interesting hairs of the blossoming very good.

Yeah, you're right, the first letter was right :)) I assumed it was just a slip of the tongue, as the saying goes, but I wanted to make sure for the others reading who maybe don't know so well the plants like you do.
Would be great if the two of them would be closer so we can 'jump' from one to another.
-
I just noticed that the first picture has a wrong name. This is Dianthus haematocalyx ssp. pindicola. From Mount Smolikas in the Pindus Mountains. 1960 meters. Northwest Greece. She is with me in the area for Sempervivum and Saxifraga ... since I have not used any labels ... was perhaps a mistake ... I'm still just a beginner. ;D
-
I found in my Dolomit-Stone-Garden a Dianthus spec. grown directly in the rock. This Dianthus survived this summer a dry period of 4 month and temperatures till 39 °C. In this time the plant developed flowers and produced seeds!
-
the dianthus spec. of the dolomit stone flowers again!
-
Nice :)
