Title: Erythronium 2018
Post by: barnclos on January 12, 2018, 10:42:40 AM
I received Erythronium caucasicum seed from Dr Pilous, and put them to soak yesterday. This morning I noticed that a couple of the seeds had 'protuberances' - I didn't take a close look at the seeds yesterday, but I have no doubt that they were already there, but perhaps a little more dehydrated/shrivelled. 

These are the seeds in question:

These seeds are typical of the rest batch.

I can convince myself that the protuberances are growing out from the seed, i.e. a shoot = germination = hooray. Is this just wishful thinking?

I am inclined to put them into moist vermiculite, so that I can keep an eye on them. Any advice will be gratefully received.

Best regards, and a Happy New Year to you all.

Keith,

The protuberances are not signs of germination but the remains of the elaiosomes, you will see them in this picture of fresh seed.

Seed sown fresh will germinate the following spring but as you have recently received and are sowing the seed now I suspect that you will see no germination until spring 2019.

You will get more information in this Bulb Log

Thanks Ian. I was initially prepared for germination next year (I had read that Bulb Log when I ordered the seed, but wishful thinking always overrides ageing memory), so they’ll get the ‘quiet corner treatment’ after all.

Good luck I hope your efforts are rewarded with flowering plants in around 7 years.

I'm not sure if these are early or about the same time and don't have any previous year pictures to check on. With all the snow in the past few weeks they have had one Hell of a lot of moisture and one E. dens-canis plant is way over.

Hello David,
                 My Erythronium dens canis in pots and under glass in cold frames flowered at the beginning of March and are now well over as well but the ones in the garden aren't showing anything yet. Hope they are still there? I have a few other Erythronium  appearing in pots as well but nothing outside at all. Its been a long cold dry spell here with no snow at all but we are getting light rain today. My father mentioned that yesterday the soil was still frozen about 5 inches down in his veg garden which would hopefully explain the lack of growth in the garden.

Erythronium albidum is almost over, while E. californicum and E. americanum are just hitting their stride.

Hi Maggi, just spotted we have two threads running.  (edit  by maggi - fixed now David)

Lovely day today for a change and wonderful to go out and leave the overcoat and scarf at home. So early afternoon we went to Wildside on the first opening of the year, pictures later hopefully. Once back home I took a chance to picture some Erythroniums from the garden. Some of these were, perhaps, a little immature but, given the recent run of weather, it could be months before we get a fine day again! One other excuse for poor picture quality really came from a voice from the kitchen window ""You're not going to kneel down on a wet lawn in those jeans are you"" reply 'Well I was, because if I don't kneel down and try to photograph on my haunches I'll be sure to fall over and squash the lot of 'em'.

So here goes:-

Erythronium 'Craigton Cream' with many stems to open yet. A strong grower from the 'Craigton' Stable.

This is one I have had for a few years now and my label says E. oregonum but I think, on the basis of my reading of Ian's book,  it's possibly E. californicum. Confirmation or otherwise? If I'd been kneeling down.............!

Erythronium tuolumnense. Last year I had two flowers, this year only one in spite of a sulphate of potash feed last year. The leaves look in good 'nick' though and Ian regards this species as being relatively quick to multiply. Oh, the snail got to the flower before I did.

E. 'Craigton 'Cover Girl' again a cracking grower.

Stunning photos, Steve! The markings on the first clone are exquisite! I'll have to look for Erythronium japonicum seed in the next seed exchange.

Sown June 2017 as fresh seed and according to Ian Young's bible, I've had the best germination ever.  The correct planting depth seems to be critical.  In the past we've only had luck with E. revolutum and that after many failed attempts with rock garden societies' seed, me to blame as I either planted them too deeply or let them dry out whilst dormant.  Once in the ground revolutum now seeds about like mad.

Erythronium revolutum Alleyne Cook fresh seed Spring 2017-
Erythronium 'White Beauty' my own fresh seed June 2017

As well E. 'Harvington Snow Goose from the AGS 16-2572 1 seed up of 5 sown, E. 'Ruapana Dawn' AGS2016-a few up and E. sibericum AGS2016-02590. No sign of E. helenae yet.

When shall we start too fertilize?  Thinking 1/4 strength water soluble as we've had excessive rains.

john - +8.3c and densely overcast. Rain immenent.

sounds like a good plan to water with 1/4 strength water soluble every time you water the babies, John...... and for the baby trilliums too.

I was delighted to turn the page in the April House and Garden magazine to see a beautiful story by Naomi Slade about Erythronium and an avid collector, the late Joan Loraine, of Greencombe Gardens. It was very interesting overall, and I particularly liked the idea of the species being laid out geographically along a path, In latitudinal degrees , between 35 and 50. Beautiful photography by Sarah Cuttle.

No worries, Michael : pictures sometimes rotate "of their own free will" -  I think it has to do with  the file info "remembering" their  original orientation !

Don't abandon portrait format altogether - you've no idea how often I struggle to get a great cover shot for the International Rock Gardener e-magazine because  people take everything in landscape format!!
