Wild collected seeds I bought from Holubeck (horridula, integrifolia, prattii and punicea) December are now germinating, and very well, too. :) The seed pots were outside all winter, under snow and I took them to cold polytunnel two weeks ago where they are now germinating. Even in M.punicea pot there are couple of seedlings coming up. I now hope I can keep all these alive until flowering. :)

Very exciting Leena 8)
I've never succeeded with punicea.

I've never succeeded with punicea.
I have tried it twice but never got the seeds to germinate, so I'm very excited to get seedlings this time.
Did you have trouble with them later?
-
No, I never got any germination so either my conditions were wrong or the seed wasn't viable.
However Margaret or others may know if there are any particular challenges in growing the seedlings on.
-
I think it's down to them needing a prolonged freeze to germinate, I never had issues in Norway, but they (the exact same Holubec seeds as Leena) haven't germinated here in Denmark... I'll keep my fingers crossed they'll germinate next spring.

Mec punicea seed should be sown as fresh as possible to get good germination.

And typical Scottish winters are cold & long enough?

I hope yours germinate next year.
Here seeds really had a long and cold period, about four monts below freezing.
I have had also very good germination from Adonis seeds this year, even older seed pots germinate now, and I think also they need below freezing temperatures for longer times to germinate.

They often did in Norway if sown too late in winter, so I'm hopeful, even if the climate is a bit milder here - x cookei was sown a month earlier and they have germinated from old seeds, if admittedly not very well. It may be that fresh seeds lack deep dormancy?

M. xcookei has always been described as sterile, so it would be very interesting to see photos of your plants when they flower. Could they have back-crossed with either of the parents?

No back-crossing, it's the only Meconopsis in my mother's garden... They're from a cross I made back in 2009 or so, I sold a bunch of them thinking it was regular punicea before realizing I had succeded. (One full pod of seeds out of some 10 attempt.) Some are loosely clumping, some running, some pink and some purple.
It's not very fertile, I have some 10 seedlings out of maybe 100 decent looking seeds collected 2019-23, although there's a chance more will germinate next year.

We know more about the requirements of M. punicea than other species because one of our members did an experiment sowing a set number of seeds every month and carefully recording the results; he found that early sowings were more successful than later ones.
As far as other species are concerned, I think all Meconopsis seed needs cold, though storage in the 'fridge before sowing seems to suffice. Once sown, ours then germinates in a couple of months. So, seed sown in February will germinate in April at the same time as seed sown the previous summer and with similar success. For the majority of species, therefore, there doesn't seem to be any advantage in sowing as soon as the seed is ripe (which then has to be looked after for longer to make sure it doesn't dry out). More detailed experimentation might find there are other species like M. punicea (maybe M. quintuplinervia?), but the majority of those more commonly grown don't appear to be.

Thanks, that's really interesting.

This is interesting, as it matches my observations - although the conclusion I've drawn is a need for a longer cold period, not that fresh seeds germinate better... I've had older seeds from Holubec germinate fine if sown around Christmas, and waiting a full year to germinate if sown in February, but still germinating well when they eventually do germinate.

"Dad" (M. quintuplinervia) opened his first flowers today, so I could get some comparison pics. Not sure if this is 3 or 4 different clones, they're all spreading, I'm guessing the clumping ones may have perished from lack of division over the years.

Really pretty M. x cookei and flowers look big.
I have sown several times M.quintuplinervia with no success, but couple of days ago I noticed that there is germination in a pot of M.quintuplinervia sown in January and pot kept outside (nder snow). :)
I am so pleased. :)
Blue Meconopsis are looking good coming up. These are Jim's ex, or maybe I should just say FBG plants. :)

Meconopsis intergrifolia from seeds from Tristan couple of years ago started to flower in late May.
They are so nice!

This Meconopsis zhongdianensis was sown in 2020, and I managed to grow one plant to flowering size. In more moist spots the seedlings died but in this a bit drier place it survived.
A very nice smallish Meconopsis. :)

Meconopsis baileyi flowering now.

The last flower of Jim's ex FBG, it has now flowered for a month!

I have several of the more common ones such as Baileyi and Lingholm but don,t know suppliers of others. I would like to try other coloured perennial species. Does anyone have suggestions for suppliers?

I have gotten most of my Meconopsis seeds from SRGC seed exchange. :)

A friend belongs to the Meconopsis Group and gets her seeds from them.

Perennial species of Meconopsis come mainly in blue, purple and white, the vast majority of yellow and red flowered ones are monocarpic. Seeds are sometimes available from perennial forms of Meconopsis punicea (which has red flowers), but in my experience these produce monocarpic plants. The hybrid between M. punicea and M. quintuplinervia is M. x cookei and the cultivar 'Old Rose' is a reliable deep pink perennial, but I know of nowhere from which this is available commercially. In Scotland, the best specialist nurseries for blue, purple and white perennial species and cultivars (many of which are sterile) are Edrom, Macplants and Kevock. The best source of seeds is The Meconopsis Group (and the Group's website is the best source of information on cultivation, identification, nurseries etc). M. sherriffii is a glorious pink flowered perennial species, but has sadly been lost from cultivation.

Thanks Margaret.

Meconopsis intergrifolia from seeds from Tristan couple of years ago started to flower in late May.

This looks like the Balangshan form of Meconopsis integrifolia which has until now been included under the subspecies souliei, but is quite distinct due to its wide open saucer, rather than cup-shaped flowers. It is probably sufficiently genetically distinct to be described as a new subspecies or maybe even a new species, certainly it is worth preventing it from hybridising with other Integrifoliae. It has become uncommon in cultivation in Scotland and only one member of The Meconopsis Group reported having successfully raised plants in 2023. So, please take care of it, hand pollinate if possible and grow more plants if you get fertile seed. Do you have more than one plant? Congratulations on having such a special plant!

Thanks Margaret. :) They were really nice shape, and also the colour was intense yellow, especially in the beginning of the flowering.
I have five plants, and three of them flowered this year. Unfortunately I stupidly planted them to different beds (in hope that if any of them died in the winter, some would survive) and so they didn't flower close to each other. I tried to hand pollinate them, but not all seed pods look good. There may be some which are good, and hopefully provide seeds, but I'm not sure yet. The remaining two plants will flower next year, and they grow next to each other, so pollination is more sure.
