Germination activity is currently occurring in numerous T. pots in the shade house of seed sown at varying depths :) .
Home- T. chloropetalum x albidum .(maroon -white centre), sown Jan 2015 sown at 30mm .
NZTG- T. erectum ,(pale lemon-wine centre), sown July 2015 at 90mm .
Cheers Dave.

That's interesting. Do you think sowing at depth gives a more stable environment? I am surprised that your seed is germinating at this time of year, a month after mid summer. Mine always germinate in spring (or even in winter this year - I spotted seedlings of T chloropetalum on 1st January. Whether they will survive the current frosty weather is another matter.
-
Dave, where do you get 90cm deep pots? ;D

Hello Carolyn
Yes I think so if the pots were outside and exposed to all the elements and of course
Ian Y has documented his experiences of sowing some bulb seed at depth .
However my curiousity was intially based on my understanding that in the wild ants can take the seed away into their nests to feed on ,so in the shadehouse I've played around and have successfully germinated T. seed for a number of years at varying depths from surface sowing ,(of T. rivale ) and other T. species right down to 100 mm as an experiment .
Whether sowing ,say at 100 mm has an effect on rhizome size and eventual time to reach flowering because of the energy required for growth to appear above the surface each season I have not yet formed an opinion on although I have mature rhizomes planted in the garden that flower each year at 140 mm depth ...........
This is about the normal time Trillium seed underground gemination happens around here although for some species this occurs in early summer however it will not be until they experience a cool period that the above ground ,green grass like cotyledon growth appears in July .
Am currently starting to harvest 'home' seed which has been very slow to mature this season .......
-
Thanks for this, Dave, I will try various depths with seeds from the seedex. I'm also going to try treating some with GA3 which a friend has kindly given to me. Perhaps it will help with the seedex seeds which have been dry stored and don't germinate as readily as fresh garden seed?
-
Have just been reminded that I have 4 pods of Trillium maculatum under protection from the birds which last year stole every pod just BEFORE it was ready to pick. These little bags have been a great find and I do thank was it Anne W? for the idea. I've been able to protect seeds from as tiny as Soldanella pusilla to as large as Iris bucharica and as elusive as Euphorbia myrsinites from loss due to premature fall or depredation from birds. I've just taken the trillium pods now, and there are maybe 125 seeds in the 4 pods but boy! do they smell FOUL?!!!
I'm assuming Dave, that the germination you are seeing now is from seeds sown LAST summer? Not within the last few weeks?

Found another 15 pots today with recent activity of seed sown Jan/Feb 2015 as well as NZTG seed sown July 2015 Lesley.

Trillium.
I would like if there is anyone who can name this Trillium. Thanks in advance.

Trillium time again!
First of all, Trillium nivale, which lives in a pot, but some day I will pluck up the courage to plant it out in the garden.
Then three photos of T. rivale, grown from seed from the SRGC seedex. The seed was sown Jan 2011, germinated spring 2012 and the young plants are now flowering for the first time. It's exciting to see the variation in colouring from one batch of seeds. My favourite is the first rivale photo, with the good pink veining.
I have several pots of T. rivale seedlings at various stages. I had a look at all the labels today. Seed of T. rivale which was freshly harvested in summer and sown immediately germinated the following spring. Dried seed from the seedex (soaked for 24 hrs to rehydrate) sown in January usually takes just over a year to germinate. I wish all trilliums were as easy as that!
-
Very nice, Carolyn - mine are still at seedling stage.
My favourite is 'pink freckles'.
-
I don't grow many Trillium but here is one growing in the darkest, dampest part of my garden. I bought it from Keith Wiley as a small plant about three years ago and it flowered last year for the first time.
Trillium kurabayashii
-
Here in Belgium the trilliums are starting to bloom. The first one is Trillium nivale.
-
Herman, what a lovely big clump of T nivale! Are they growing outside? Under what conditions?
-
Yes Carolyn, they are growing outside in humus rich soil in semi-shade. This one stand under a tree (from our neighbour, leaves appear very late), so it is a very cool position in summer and now it gets a lot of light. Another plant is standing in more shade and flowers always much later (about a month). Once they are settled they dislike removing.
-
Thanks, Herman, that's very helpful.

Very unusual and very lovely, Michael.
-
What a beauty Michael! Something genuinely new and exciting and a great basis for a new hybridizing/selection programme if you wanted to go down that track. Whatever, keep up the good work and thanks so much for sharing this lovely plant with us.
-
Super colouring, Michael. Are you going to let us all in to the secret of how you managed this?
-
Not yet. ;D ;D ;D
-
Trilliums started blooming here 3 weeks ago. A few, like T. sulcatum, are still to come.
Trillium rivale, various forms
Trillium 'Blondie'
Trillium sessile, a gift from a fellow NARGS member
-
More trilliums:
Trillium kurabayashii
Trillium cuneatum
Trilllium chloropetalum, T. cuneatum, and T. albidum
T. kurabayashii has seeded all over both front and back gardens. I sowed a single seed exchange packet of T. chloropetalum years ago and planted the whole seed pot in one spot. I thought I had a white T. chloropetalum but a friend tells me it is T. albidum, a stowaway!
-
The brunnera looks good with the groups of trilliums. Lovely.
-
Beautiful pictures Claire!
-
T.cuneatum looks very beautiful to me, such distinctive leaves with dark flowers!
Your last picture is very informative, to compare the size and color of the leaves of different kinds. :)
-
One of my T. rivale seedlings.
-
Trillium rivale blue. Here is a nice blue marked Trillium rivale that I produced last year.
That's superb Michael, completely new to me. Bringing seed to Chernobyl or Fukushima are you? ;) ;D
Wonderful big clumps Claire. Are the seedlings far from the parent plants, maybe distributed by wasps?
-
or a flower in an inkpot?

Ashley, I know you were only joking but you are closer to the truth that you realize. ;D ;D ;D
-
Michael and Darren, you have gorgeous Trillium rivale colors.
Here's Trillium pusillum, started from a single bulb 11 years ago.
As for trilliums spreading in the garden, I suspect ants do the deed.

Trillium luteum and T. hibbersonii, the latter dwarfed by Erythronium revolutum leaves.

-
Trillium albidum (Z119), Trillium angustipetalum (OBW87), Trillium cuneatum (H19) and Trillium pusillum var. pusillum (OBT131)
-
very nice Hermann. Thank you for this pictures.
-
A nice pink form of Trillium rivale I got from Kevock a few years ago and a pot of seedlings from it with the first flowers. The seedling pot is a bit overexposed. The flower at the front is about the same colour as the parent but the one in the middle is darker so should be interesting when it is fully open.
-
Nice pink T. rivale, Roma!
I picked up this Trillium chloropetalum as a small (probably second year) seedling at the SRGC Edinburgh show in 2012 - it came with the warning "7 years to flower, young man!" I seems to be a good form, increasing to two stems of flowering size in its first year of flowering and with excellent patterning to the leaf.
-
Beautiful chloropetalum Matt!
I have sown Trillium kurabayashii yellow in October 2015 and there are already 3 seedlings with one leave!
-
My one and only Trillium rivale from the garden today
-
And it's a beauty, David.
-
Thanks Roma. I can't claim any skill in cultivation having bought it at a visit to Ashwood Nursery last month. I just hope it re-visits me next year.
-
Trillium chloropetalum giganteum album which also bloomed in the garden. I'll move the brush on the stamens and stigma because I would really like to see him produce seeds this year.

In a fortnight's time, here Trillium rugellii which developped. Several photos show its evolution. Soon, the flowers will open.

I do not know where to put it, but it's a close relative. The festival of plants of the Enghien castle in Belgium. I brought a Paris Polyphylla.

Well, it comes from the plant nursery 'Shadow Promise': http://www.promesses-d-ombre.be/ (http://www.promesses-d-ombre.be/)
The owner, Thierry, is adamant about the name.
PS: If I can not put link, Maggi, tell me, I withdraw it or you do. ( note from maggi - no problem Fred! )
-
Hello Herman.
They should be planted under my large rhododendron, so there's Trillium everywhere.

-
Is this leaf damage on my trilliums caused by a virus? I've noticed it for the last 2-3 years.
-
It could just be weather damage Anne.
The buds on some of our Trilliums appear through the ground in late autumn early winter then sit exposed just on the surface and are susceptible to frost and other damage - in these ones we sometimes see similar damage to the leaves as you show but they display no other symptoms of virus and it does not happen every year.
-
I hope you're right, Ian. I think I might mulch heavily next winter and see if that helps.
-
Trillium problems.
I'm having trouble T. foetidissimum, T. ludovicianum, T. lancifolium and T. gracile they do not come up. I have 15 cm deep hole, soil mix: peat very coarse sand, beech kompots well with sinks, what am I doing wrong? Does anyone have a good soil mix for this Trillium?

Stunning T. simile cv., no wonder is called jeweled wakerobin!

Some years I get a small percentage of fresh T. seed germinate quickly just after late summer sowing .
Here's this seasons T.chloropetalum seed ,harvested and sown 12 weeks ago on the go with about 8 seeds out of 40 currently germinating , so that's about 20% in this pot so far .
A number of other T. pots with this seasons crop are also showing activity and I wonder if it's been the consistent warm temps we have had so far over autumn. (a lot cooler today but forecast to reach 20c later in the week and night temps still in or near to ,double figures).
Cheers Dave.
-
I was pleased with SH seed sown March and May 2015 all germinating within 12 months and seed sown in August 2015 emerging now, but you win Dave ;) ;D
-
I have sown Trillium kurabayashii yellow on 30/10/15 and I see now already one leaf of 3 seedlings. It is the first time that I see this, probably because of the fluctuations of the temperature during this winter.
-
It's my experience that if the autumn is relative warm a decent number of seeds of Trillium kurabayashii will germinate the first spring after sowing, more will germinate the second spring. This year I got the same experience with seeds from Trillium camschatsense that were bought from Yuzawa Engei and sown early August 2015: a part of the seeds germinated a couple of weeks ago.

I've located some postings on 'Trillium L ' that mention 'seed recently collected or nearly so will produce a cotyledon the first spring after sowing if given appropriate treatment such as being kept warm 21c,(70 f),for at least 90 days before any chilling' .
Since my last comments a week ago I've observed all pots of 'home' Western seed sown Jan/Feb 2016 germinating ,(root radicle just forming or onwards), although we haven't reached day time 21c consistently since being sown .While there is quite a variation of activity at this stage in each pot there are 3 pots that have a near 100 % germination rate something I've never had occur this early after sowing ...... No action yet on any of the 'home' eastern seed sown this season ......
Here's a pot of seed from home 'garden raised Western Trilliums ' showing about 12 seeds germinating so far out of 15 and some examples of radicle appearing.
It will be interesting to see how long it will be until the cotyledon growths appear after a cool period ...... ( Whatever those required temps and duration are ? ).

This Trillium chlorpetalum var. giganteum f. rubrum was a great disappointment, delusionally we thought it might improve in time but alas seems to be a dog. Well maybe not quite a dog but neither big nor red, could be worse I suppose.

John, I do not find it ugly, on the contrary. I have a home that is with white flowers, I saw with white flowers with purple petals base. It seems they have a strong character variable. If one day you will get rid, think of me. ;D

Dave - I'll be in touch if it sets seed. I'll check your bio-index to see if ok.
And Fred - Guess we should accept it for what is is rather than what it should have been... ;)

Trillium chloropetalum is definitely OK John. I wish you could come here and see Dave's trilliums in the spring. I would have been happy to lie down and die among them last October and while I like them a lot, I'm not obsessed. ;D

Leena, the best way is to compare the berries.

Thank you Herman. :)
I got a seed pod from it two years ago when it first flowered, and I remember thinking that it was small, and even if the seeds were viable. There were two seeds, and both germinated this spring. :)
-
Surely I didn't malign Trillium chlorpetalum var. giganteum f. rubrum last month! :-[
Here it is almost a month later and still putting on a show.
john - cloudy & 12c
-
Beautiful Trillium John. Thanks for showing! Can you also take a picture of the berry when they are ripe? Thanks in advance.
-
It IS a beautiful trillium and a nice picture, too. :)

Spring has arrived here in the southern hemisphere with the first Trillium just commencing into bloom with many not that far away........
