Germinating now- - photos of seedlings

[Gabriela]

Nice NA collection

Found a bunch of germinated pots outdoors on Sunday and while fresh in my folder I would like to mention Campanula saxifraga – this species is reported by some as warm germinator or after a short cold period (which I tried last year and didn’t work for me).

It comes to show well that in some cases there is no clear cut method for germination and that the genetic component and seed provenience has a greater influence on germination than thought before. The second ed. of Baskin & Baskin book Seeds - Ecology, Biogeography, and, Evolution of Dormancy and Germination, has an interesting chapter on the subject (a bit heavy book from all point of views though).

And here three times pictures of seedlings, where I got the seeds from  members of the forum ...

Silene davidii 10.03.17 from Philippe
Bellevalia sp ex Iran 27.12.16 from ebbie
Digitalis obscura 27.12.16 from GordonT

Thank you again ...

Rhododendron mucronulatum var taquettii from seed ex germinated already in the end of February, but they are looking like this now. Soon ready to be pricked out. Thank you John.

Romulea sabulosa from the 2016 seedex were sown on Feb 14th 2016 and one germinated that summer.  The seedling to the left emerged on Feb 14th 2017, one year later.

. John, did you have these inside or outside? Do they require any special conditions to germinate?

They say in a greenhouse the whole time, temps in summer got to 40c on many occasions as the ventilation was turned off and the doors opened erratically.  The 7.5cm deep pot may have been water once a week at best.   One more seedling has since come up.

After a first this year with Crocus and Galanthus from seeds, here comes more - Erythroniums. This forum is contagious
I never bothered to sow E. americanum but last year I kept some seeds for myself.


Erythronium dens-canis - thank you Trond!

My second pot of Lilium matagense (Bjørnar's BO-16-065) has germinated with all 9/9 seeds coming up. They were planted in January in the cold frame, but it has been crazily warm here (around 20 °C most days for the past 3 weeks), so they got moved to the pit which allows light into our basement (in French, this is called a soupirail; is there a word for this in English?) on the shady side of the house where the temperature only gets up to 13 °C.


Next are a couple of species of which I have no previous experience.
Rhodophiala montana was in the fridge in moist kitchen paper for 15 days, then into the soupirail. First germination was 21 days after being taken out of fridge. Only 3 (from 16) germinated so far.
   

Rhodophiala splendens had the same treatment as R. montana. So far, just a solitary seedling, 24 days after coming out of the fridge. So fingers crossed for more.

Very elaborate labels, Keith ... my respect.

Some nice new species starting to germinate here. I'm especially excited about Linaria michauxii.

These were all planted March 24, last year.
With no. 2 grit cover, I thought the "hook" on the end of the emerging Iris histriodes was interesting....

Campanula choruhensis (no.1 grit cover)

Allium paradoxum normale:
--- left - 4 weeks at 4°C, then outside in natural spring, summer, winter and (now) spring.
--- right - 4 weeks at 21°C, then outside in natural spring, summer, winter and (now) spring.

Sanguinaria has started to germinate few weeks ago but I waited to be sure I have all lots to compare. As known Sanguinaria seeds can have a deep simple epicotyl dormancy and also a double dormancy (germination in 2 years). By the look of the different pots/seeds coll. in different populations it seems that it's not random (like it often happens with Trillium grandiflorum) but very much related with the collection site.
Sorry I don't keep neat labels so you have to trust what I'm showing:
Seeds sown in 2015 – germ. 2017.


Seeds sown 2016 - germ. 2017


Few others
Minuartia circassica


Ornithogalum hajastanum


Hydrophyllum virginianum (as well with simple epicotyl dormancy)

This is interesting. I sowed S.canadensis from my own seeds in summer 2015 and they are germinating now.

At the Beginning of 2014 I sowed Aquilegia saximontana, seeds coming from Alplains/USA. One seedling came up but did not survive. The box stood in a plastic case in a corner outside since then. Last week I wanted to clean it up and that's what I found:

After more than three years! I hope they will survive this time.
