Interesting Magnar ! Here only few germinating at the moment .
Rhododphiala is one of the very few....

Kris - Same thing here. R. ananuca came up this past weekend.  About a week or so since I sowed it.

So it looks like they keep more or less the rhythm of their homecountry John , don't you think so ?

I really don't know Kris.  I having been trying to figure out their rhythms for quite some time. Seems they sprout when sown and moistened, after that I am at a loss.  I sprout them warm in bags and then move them under the coldroom lights and in late Spring into the greenhouse wehen there's more room.  I have been trying to keep notes on when the various species go dormant and then start to grow again.  In fact a few have just started to grow in the cold greenhouse and I will record which and give you a list of which species do what. There may be some holes, those ones may be permanently dormant.

I may have some araucana seed which was identified by Alberto in a posting as should you need any. I did send it in to the seedex though and you may be growing it.  BTW the yellow form selfed gave poor germination but I have have moved it into the cold prematurely.  Some may have received this species as elwesii in the past.

Many thanks for your comment John . I sown 4 or 5 different species this year .So far only one is germinating. I have one young plant that's refusing to flower for the moment. It is one that I obtained from a nursery. But it is strange because it make some leaves each year but always on different moments ..So I don't know if I treat them right ?
Yes , I wan't to trie that aruacana ...

Kris - PM your address to me and I will post them tomorrow.

Three more R. bagnoldii and two ananuca (of which I know nothing about) came up overnight.  Which species was it that you obtained at the nursery. I might have some notes on it?

Some of mine do much the same thing. It probably does not help that some of the dormant ones mistakenly get watered in the winter, especially if they are hiding amongst the leafy ones. The araucana never goes truly dormant here and puts out new leaves in very late Spring and then again in early winter though in less profusion.

And these Rhodophiala came from Santiago and germinated last month! (Attachment Link) cheers fermi

Fermi    - These look happy enough and I guess safe to say it is a happy summer-grower. Can you tell us which species it is?

Kris - I did a quick run-through the Rhodophialas to check which were dormant and which starting to grow in the cold (5c) greenhouse.

Sending leaves out half-heartedly so I assume winter to late winter-grower:

araucana
splendens
species ex Ashley
phycelloides

Growing away:

advena (some say shoots in September)

Dormant:

rhodolirion (not dormant but dead)

andicola (not dormant but dead)

1 shoot coming slowly but strongly:

pratensis

Seeds sprouted immediately - bagnoldii (said to shoot in Sept.) and ananuca

Seeds didn't sprout so moved to cold room  - andicola (Ashley says it may require a cold treatment)

I don't know how reliable my findings are, compare the above with Ashley's notes below:

Notes:

true elwesii - fresh growth in late August/September, almost evergreen according to Ashley
laeta - fresh growth in late August/September, almost evergreen- Ashle;, never sprouted for me here.
montanum  - begins to emerge from early/mid-October - Ashley
phycelloiudes - begins to emerge from early/mid-October - Ashley
rhodolirion - begins to emerge from early/mid-October - Ashley
serotina - shoots in September after first watering - Ashley
splendens - shoots in September after first watering - Ashley
species cw - shoots in September after first watering - Ashley

I don't know if this will be at all valuable as the greenhouse is quite cold though it can get warm on sunny windless days from now on.

John,
They are 2 forms of Rhodophiala bifida - in growth in summer because they are newly germinated, I think.

New germinations all sown a few weeks ago:
Puya mirabilis from Kristl,
330400-0

Aristea ecklonii from Nicole
330402-1

and 3 from Marcus Harvey,  
Salvia sclarea
330404-2

Salvia pomifera
330406-3

and Ebenus creticus
330408-4

cheers
fermi

I wish you luck with the Ebenus, Fermi, - it is a lovely plant and I see from the NARGS site that it had a narrow escape from rodents?!

I once grew a couple of seedlings and one even flowered but the plant really resents our cold wet winters even under glass and they soon died. Your climate should suit it much better!

Magnar: the list of seedlings in your reply #60
( http://www.srgc.org.uk/forum/index.php?topic=6490.msg230356#msg230356 )

Did they also all germinated at room temperature without a cold treatment?

I would like to encourage everyone to to give specifics on your germination experiences (temperature, duration, surface sowed/at depth,etc.).  It's wonderful that we can see what the seedlings look like, but just think of how much more valuable this thread would be with this other information included!

I love this thread as this is surely where it all starts.
I agree with you Rick that as much information as possible alongside the pictures would be very valuable. Generalisations within the various genera are usually OK, but sometimes the less cultivated species have different requirements, and therefore often lead to failures for the less experienced, and often to resignation. I will try to fulfil your requests when I post on this thread Rick.

Just don't overdo it, as I did so expertly last winter, and kill them all  :-[  :'(
Temperatures in my greenhouse got down to about -5 to -8oC but probably more importantly, stayed low for several weeks.  This proved fatal because most of the rhodophialas were in growth with moisture at the roots.
