Here is - rather early - Primula megasaefolia (nearly hardy outside but for safety in a pot)

Rudi, have you seen Jon Evans' report from Pershore AGS Show ?
It is here:
https://www.alpinegardensociety.net/plants/pershore-early-spring-show-2020/ (https://www.alpinegardensociety.net/plants/pershore-early-spring-show-2020/) - look out for fine plant of Primula allionii ‘Elke Weiss’ - named for your charming wife !
-
Maggi, thank you for the notice of Eric Jarretts Primula allionii Elke Weiss.
There is only a small problem: The picture shows a beautiful plant, but is not Elke Weiss.
Attached are 2 Pictures of the true plant.
-
Oh dear, that's a shame - we must let Eric Jarret and Jon Evans know.
edit to add, Eric Jarrett has confirmed to Jon Evans that he's grown the plant for around ten years and the name may have got muddled.

just a few in flower today

Compare Steves P. frondosa with my picture of March 2020 in the northern hemisphere reply 81. I can,t remember if I bought the plants of P. farinosa or grew them from seed. It is early for farinosa. I,ve read descriptions of both species and wonder which mine is.
-
Ian, the AGS Encyclopedia says that P. frondosa and P. farinosa are very close, the main differences being the length of the sepal lobes relative to the length of the calyx (1/3 vs 1/2), and the shape of the sepal tips, which are acute in P. frondosa and obtuse in P. farinosa - my own plant definitely fits P. frondosa on both characters. It is difficult to be certain from your photo, but I think the sepal tips on your plant are also acute rather than obtuse. When I ordered seed I chose P. frondosa in preference to P. farinosa because it is supposedly much easier in cultivation.
-
Thanks Steve, I,ll need a magnifying glass. Latin was not a language in our school.
-
The sepal lobes on my plant are acute. The length of the sepal lobes seem to be about half as long as the calyx. It was the flowering time which made me wonder which species I had. I,ve seen P. farinosa in the wild twice, flowering in late May and early June at another location. My plant seems more robust than P. farinosa.

Primula sieboldii 'Fuji Shishi'. I seem to have accidentally developed a collection of sieboldii after admiring the plants at the East Anglian show. This one is the first to flower this season.

Self sown Auricula seedling in the greenhouse. The parent plant is an unnamed Rumbling Bridge hybrid with farinose leaves and pale greeny yellow flowers. I collected a few seedlings from neighbouring pots (no other primulas near) and all the offspring have had blue or mauve flowers.

I love P.sieboldii, and especially the blue ones are my favourites, though I have only one seed-grown blue P.sieboldii. It is my treasure. :)

Here is Primula marginata.

Another blue-ish Primula sieboldii 'Kiraboshi', although my camera is recording it as more blue than my eyes see it - it has a magenta tint in real life.

Primula kisoana spreads in my garden. The white form is a pin, and both pin and thrums show up in the pink form. Here is a nice dark pink form.

Beautiful Primulas from all! I need to grow a few more species, a bluish P. sieboldii would be more than nice.
Stefan - is that P. frondosa in wild habitat?
Only P. vulgaris ssp. are in flower here. I understand is practically only the flower color that distinguish them from P. vulgaris.
P. vulgaris ssp. sibthorpii (or hybrid), very early even by its standard, in full flower last week.

Hi Gabriela,
It is a wild plant found only in the Central Balkan Mountains, Bulgaria. A rare and protective species. The seeds are from Gatineau botanical garden - Canada.

Sorry Stefan, I forgot to open this topic. Thank you, yes I know is endemic from Bulgaria that's why I thought maybe you had the chance to see it in the wild. Interesting you grew it from Canadian seeds origin :) I also have it in the garden, should start to flower soon.

I think this is Primula septemloba, grown from wild-collected seed. It completely disappears in winter.

Not one I am familiar with - but, as usual, Pam Eveleigh's Primula World site has information.....

1. Primula waltonii, sown 28 January 2018 from SRGC seed list 2017/2018-3090, listed as Primula ioessa. First flower opened 18 May 2020, other seedlings just start to flower now. It's not unattractive with its very deep claret flowers that become lighter with age, but I'm a bit disappointed that it isn't P. ioessa.
[attach=1]
2. Primula grignensis, or at least bought under this name. I don't see any difference with P. hirsuta.

Hello Andre, shame about the not-ioessa.
I think the differences between grigensis and hirsuta are very slight .....
quoting Primula World ....
Primula grignensis D.M.Moser
Section Auricula, Subsection Euauricula
Type specimen: D.M. Moser s.n. 25 Mai 1996, Italien, Lecco, Cresta Cermenati, 1950m resides at G (specimen G00440611).
Reference paper: S. Creme & G.Cristofolini, Phylogeny of Primula Subsect. Euaricula - A case study on origin and evolution of alpine endemism (http://www.destradigelagarina.it/UploadDocs/4971_art07_crema.pdf), Ann. Mus. Civici-Rovereto 28: 135-159. 2013.
Epithet: Named for Le Grigne Mountains, Lake Como region , Italy.
Distribution: Italy
A close relative of P. valcuvianensis and P. hirsuta but distinguished genetically (See reference paper). This species is found growing on limestone on the Italian Grigna massif, above Lake Como. In the original description this species was compared with P. daonensis by having less sharply toothed leaf margins and calyx lobes actute, and compared with P. villosa by having smaller leaves and glandular hairs that are not red. Compared with P. hirsuta the calyx lobes are patent with the tube (spreading in hirsuta). This species hybridizes with P. auricula in the wild.
-
Thanks Maggi. I know that reference and have even compared the calyx lobes in photos of P. grignensis from the type locality and P. hirsuta* from other places. I can't find any difference whatsoever. The main distinction seems to be that P. grignensis grows on limestone, whereas P. hirsuta grows on acidic rock types. My plant seems happy enough without limestone, but that doesn't prove anything.
*Take this photo of P. hirsuta for example: https://www.biolib.cz/en/image/id142919/ (https://www.biolib.cz/en/image/id142919/)
The calyx lobes are not spreading at all.

Primula bella. Seed ex Holubec (as P. nanobella, which is considered a synonym). Sown on 22 December 2019 in a mix of equal parts ericaceous soil and grit with some sharp sand, stood outside without protection. First germination 19 February 2020. The tiny seedlings pricked out in May in ericaceous soil + grit, always kept damp and out of direct sunlight but without overhead shade. First flowering 2 October 2020. The flower is 13 mm across and the largest rosette is 2 cm across.
This is a high-alpine Chinese species (Yunnan, Baima Shan, 4400 m) which I expected to be difficult to keep alive, so I am pleasantly surprised how well it has done - so far. It even survived a heat wave with four days above 35 degrees Celsius. Whether it will survive the coming winter is another matter; I plan to give it some protection against winter wet.

Very nice and well done!

Primula auriculata seeds were sown last December, pot kept outside for the winter and they germinated in spring, and now it looks to me like they might flower next spring:). So fast. I'm really looking forward to seeing them flower, I just hope they survive the winter.

The summer rest of Primula palinuri is over and new leaves start to grow again.

chinese species are gorgous, the leaves of this one look attractive.
Did you let the pots without protection during 2019 winter?

That's a lovely little primula Andre! Congratulations.

An update on Primula bella (apologies to Yann and Tristan – I had not seen your replies, thanks for them). Most of the plants survived their first winter (20/21) outside but protected against rain. They formed new rosettes in the spring but these did not flower in 2021. When they went dormant in the autumn of 2021 they did not seem to have formed proper resting buds and none of them reappeared in 2022. Perhaps this species is naturally short lived, or perhaps they were kept too damp in the autumn. It is often hard to tell why a plant fails. Unfortunately, it will be difficult now to get seeds of this Primula again.
