Nice results for your first flowers, Tony!

Crosses are always so much more fun, intriguing, somehow more meaningful and pleasantly surprising when you do them yourself.  As you know, it's not that terribly uncommon for colors to pop up "out of no where" with Lilium hybrids.  I wonder how often it happen in Iridaceae?

Here are some of my germination records this year.  Lori, you passed along the incentive to document and save germination times and methods!
Warm germinators are put under a three shelf double fluorescent shop light set up. Cold treatment is either basement 4-10C in January, February or cold mudroom (alternates from 0C to 4C).  Longer outdoor treatment is done in an unheated greenhouse.  This winter in central Ontario, Canada we've had more snow with fewer severe dips (-25C -30C) in temperatures but longer lasting than in past years!
My simple rock garden is still snow covered but in a dry scree like area shoots are finally showing and brown is turning to green. Crocus are just starting to flower!

Wow, what a fabulous collection, Sharon!
From where did you get Arabis lemmonii?  It's not one that gets much attention though I think it's very interesting (have only seen one once).
I got home this evening from a conference and was delighted to find that Pedicularis densiflora has germinated!  My fitful previous attempts with a couple of other species were total failures.  More detail to follow...

Lori, the Arabis lemmonii came from the British Columbia Alpine Club.  I was attracted to its succulent looking leaf formation in your photo on another site!  Did you not have this in your garden?
The Pedicularis at first looks like Echium.  I’m sure it will be a relaxing plant to admire, kidding.  It seems to be of some ethnobotanical interest to some?  You never know what will turn up using Google!  Seems I received seed from this year’s Seed Exchange too but didn’t get it sown!  Will try it in a vermiculite bag.

Here are further germinations as of April 12, 2013. Seed sown in January through to the beginning of this week.

No, and I've only ever seen it once in the wild, which was when I took the picture!  I must watch out for seeds.  I also found the succulent leaves most interesting.  

Another amazing collection of seedings!!  Are you filling some new alpine beds?

Calceolaria biflora - germinated in 36 days at room temperature.  I had a couple of purchased plants winter over outdoors here many years ago, so I'm hopeful...

Updates on:
Cryptantha paradoxa - germination started in the cold after 6 weeks chilling; (NB. Alplains says this one doesn't need stratifying but recommends scarifying).

Penstemon erianthus v. redactus - germinated in the cold after 6 weeks of stratification:

Eriogonum robustum - in the cold room for 6 weeks; germinated in 3 days at room temperature:

Cryptantha humilis - 6 weeks chilling; germination started in 2 days at room temp:

Eriogonum ovalifolium v. eximium - germinated in the cold after 6 weeks of stratification:

Cryptantha caespitosa - germination started in the cold after 6 weeks stratification:

Campanula scoparia - germinated in the cold after 6 weeks stratification:

Hypericum pallens - emerged in 13 days at room temperature.  But only one germinated out of 20 seeds!
   

Oenothera caespitosa ssp. crinita - emerged in 10 days (the large one) at room temperature, and the others in about 17 days.  This seed was wild collected by John Weiser (Thanks!).  I need to transplant these!
   

Phyteuma serratum
- emerged in 16 days at room temperature.
   

Three Townsendia spp., all planted at the same time at room temperature.
Townsendia excapa - emerged in 12 days.
   

Townsendia rothrockii
emerged in 5 days.  On the bottom left, you can see what the seed looks like, still attached to the seedling.
   

Townsendia spathulata emerged in 6 days.

Aquilegia canadensis Little Lanterns emerged in 17 days at room temperature.
   

Allium sacculiferum emerged in 18 days at room temperature.  When I transplanted these, the little buggers' onion smell was easily as strong as mature plants!
  And thanks for the seed, Mark!
   

Physaria didymocarpa emerged in 5 days at room temperature.
   

Erigeron pinnatisectus emerged in 4 days at room temperature.
   

Iberis taurica emerged in 5 days at room temperature.

Wow, lots of good looking and promising seedlings coming along.  Lori, happy to see that Allium sacculiferum is coming up well.  And what is Aquilegia canadensis 'Little Lanterns' like?

My seed sowing fell miserably behind this year, changed jobs in November and scrambling to learn the new role, was very busy and traveling quite a bit, then became ill for approximately a 3 month period, finally surgery and now recovery.  That said, I'm glad I did sow some seed last autumn, because now most flats are showing germination.

My seed flats spend the winter outdoors, protected from squirrels and chipmunks with wire mesh.  In this photo, I removed the wire on three flats, I bend the wire to be more hoop-house shaped as the leaves and stems grow.  The top two flats are Jeffersonia dubia, and the bottom flat is Epimedium grandiflorum f. flavescens 'Nanum' open-pollinated seed.  To the left of the top-most open flat, you can see more seedlings, that is Jeffersonia dubia Korean Form.

Epimedium elongatum; even with small seed pots I cover with wire mesh.

Anemonopsis macrophylla; germinated last year, flat left on ground overwinter, and young plants are ready to plant out.
