Trillium ovatum maculatum
A bonny wee thing and a new one on me!!!
-
Maggie,What is the difference between ovatum and ovatum maculatum ?Presumably it is much earlier as my ovatum aren't showing colour yet in spite of the difference in climate between your location and my own.

The difference is the patterning on the leaves, John. T. ovatum has plain leaves. Ours are hardly showing at all yet. showing

And so it begins......Trillium rivale
Julie, is yours a mature plant? What is the diameter of the flower? Mine, sown 2010, is going to flower over the weekend for the first time and I am interested to know how much bigger it is likely to get.
Erle
Anglesey. Are we going to have a fine week as suggested by Met Office?

Julie, is yours a mature plant? What is the diameter of the flower? Mine, sown 2010, is going to flower over the weekend for the first time and I am interested to know how much bigger it is likely to get.
The seed from Northwest Native Seeds (unfortunately no longer in business) was planted in 2008 and this is the third year of blooms. The average diameter of the flowers is 2.5 cm (photo 3). The height ranges from 5-15 cm. Very cute and quite small. Excellent veining on the leaves. (photo 1)
I also have some from T-List sown in 2006 and the first flower of those opened today. They have deeper purple spots (photo 2) and do not have the veining.

Trillium cuneatum budded.
Trillium kurabayashii showing color.
Trillium ovatum in various stages.
Trillium chloropetalum sown 2007 blooming for the first time.
-
I'm developing a theory that west coast trilliums and their seedlings flower according to their
home latitude.
All my ordinary ovatum are native to my property (in Canada) and have not emerged yet.
Julie lives south of me and hers are up and flowering. Are yours native to your area, Julie?
My ovatum maculosum (as published by Case) have been flowering for a couple of weeks. It's
from northern California.
I wonder if we could have a floral calendar if someone planted a bed of ovatums from the whole
of the range.
-
Aha! I see we have been giving the lovely little marked trillium the wrong name - I have changed my post above and edited the Bulb Log to give the correct maculosum :) Thanks, Diane!

Hi Diane neighbor to the north. Yes, all of the Trillium ovatum are native to our property and they are the only ones.
My T. kurabayashii are just now beginning to bloom. Reports are they have been blooming since at least mid February in northern California (of course now I can't find where I read that). T. rivale (aka pseudotrillium) flowers started opening a few days ago and "they are in full bloom in SW Oregon" (Kelly Leonard facebook Trillium group).
-
My plant is more like Julie's 2nd one. Diameter 30mm.
This seed was JJA 1.922.320 described " Cultivated seed from Boyd Kline's garden in Medford, Oregon , including pinks & his 'Purple Heart'. Very local on the serpentines of the Klamath ranges along the California-Oregon line & one of the dwarfest."
I think I have 4 plants in this pot and will have to be brave and re-pot later in the year. As a plant of serpentine soils do I need to make a special mix for them?
Erle

Hi Erle,
The following is from one of Russell Graham's posts to T-List
"What I have read suggests rivale "never" occurs naturally except on serpentine. Yet it is grown successfully in gardens in many parts of the world without any exceptional effort to modify the "local" soils wherever the plant is grown, other than to offer typical garden soils which may be quite unlike a serpentine environment."

I have found they do quite well in our garden beds which are also quite unlike a serpentine environment.
Very beautiful seedlings Erle. I'm hoping as more of my T-List seed opens, some will be as dark as yours. Unfortunately, I never ordered seeds from JJA.
Julie

T. rivale in any of its forms grows brilliantly in just about all the South Island of New Zealand, most of the North Island and the cooler parts of Victoria and NSW in Australia, without any soil modifications at all, so far as I can gather. Just a coolish, leafy soil suits it fine, and not drying out completely at any time.
-
I think the importance of serpentine soil is that many plants can't grow in it, so it cuts
down the competition for those that can.

I am sure that is correct , Diane. I think it is often the case that plants can tolerate certain conditions, rather than actually requiring them.
-
I have this pot full of Trillium chloropetalum giganteum sown summer 2010 and germinated spring 2011. They have remained untouched since then. When do I either re-pot them or plant them out please?
-
We'd leave them be for a bit yet, Graham - plant them out when the parent plants would be going past flowering. If they are in an open compost in that pot, so you could tip them out without damaging the roots, then you might be able to split them for planting out from now - otherwise wait till May.
-
Thanks Maggie. I will leave them as you suggest.
-
Or, you could leave them as a group and plant the whole lot in a larger place, either a pot or I'd go for a spot in the garden, to give them ample expansion room without having tiny plants separated and fending for themselves. Maybe separate them further in another year.

The honey bees have been enjoying my Trillium rivale :-)

Starting here too
T chlorapetalum and albidum
-
Wonderful to see our local California native Trilliums in a garden setting on the other side of the globe. They look great! Hopefully, I will be posting photos from their native habitat in about a month - some snow on the ground where they live, especially T. albidum.
-
Hi Ian you have a lovely garden. Your Trilliums are looking fantastic :) I'll have to pinch the idea of putting my T. albidums in front of my T. chloropetalum var. giganteum it really makes them stand out, and hopefully you may get some interesting seedlings? Here is a photo of mine with with seedlings which I have waited years for!

Thank you Jane. My garden does seem to suit some of the trilliums and I get a lot of seedlings from some. You can see seedlings under the plants shown below. These are a couple of rivale plants the first one from seed many moons ago and though quite plain makes a nice show and a special one I have as Winifred Murray
-
Winifred Murray is a stunner Ian. How long have has she been growing in the garden and can I ask where you purchased her from? I think I could find a spot in the garden for a beauty like that :-)

I got this from a very good grower of trilliums about 5 or 6 years ago I will PM you with a contact
-
Lovely lovely Trillium pictures, and I love to see them in the garden settings. It gives ideas and inspiration while I wait for my seedlings to grow.
Thank you. :)
-
Trillium kurabayashii mixed shades from seed flowering now.
-
Is anyone else finding exceptionally good flowering on trilliums this year? Mine are flowering better than ever before. Must have enjoyed last year's weather, I suppose.
-
A bit too early for flowering here except T. nivale,,,but there are good growth and germination in my benches.
-
finally Trillium nivale is in bloom

Hello Jonny
I would like to know how long you have your Trillium in pots before you plant them in the box? Picture1

Well Anne, the T.sessile I got from you last autumn has come up with 3 shoots and all have flower buds. Very pleased with a great plant.

Thorkild...they go out of the pots when they show 3 leafs...

Thank you, Jonny

My Trillium pusillum that grow in a trough have so far failed to appear this year.
My T. ovatum hibbersonii are back again which is good to see because a few years back they failed to come up. I'd like to move them where I can enjoy them and they don't get crowded out. When can I do this or should I just leave them where they are?

But don't they look good alongside that dark celandine!
-
They do but I have no idea where the celandine came from but need to get rid of the dandelion and welsh poppy

Trillium albidum, given to me as a little offshoot. First flower (after 3 years) - hooray!

Very hard to establish trilliums in this garden; too hot and dry most of the time. However, this Trillium grandiflorum planted under an old apple tree 18 months ago seems OK.
Which reminds me that I never finished my account of our trip to Ontario last May; note to self, get on with it!
-
Two photos of Trillium:-
kurabayashii

They are now seeding about the garden as can be seen in the last photo.

I've had good germination from Trillium rivale seed kindly sent to me last year by Claire Cockroft. I thought I had read somewhere on the Forum, but can't find it, that it would now be best to plant the whole potful in the garden? Could someone clarify for me please.

David
with my trillium rivale seedlings, I grow them on in pots until they have three leaves.
I do not let them get dry at all & occasionally feed with half strength tomerite.
If they need repotting I just move the whole potful into a larger pot & keep growing on.
In the third year they will start to flower, they can then happily cope in the garden.

Many thanks for clarification Mike.

Thank you from me, too. It is encouraging to know that they could flower already when they are three years old. :)
Would you grow other species also like that, in the same pot until flowering?
And wonderful pictures, they show the differences so well.

Me too, but I sowed them in a seed tray so will have to prick them out Doh!

Leena
Not all trillium flower so soon, albidum & kurabayashii are about 5 - 6 years flowering from seed.
But I do the same with the two mentioned above & just keep moving the whole lot into larger pots when necessary.
Mike
-

Yes - we do that, moving en masse to a larger pot, as Mike says, or often in a fish-box trough if we happen to have a lot of seed, or using one trough for different lots of seed. They can grow undisturbed for a few years and this seems to make good strong plants. If they are very lucky, they might get some feed after a couple of years!
-
Trillium chloropetalum-I think
-
Thank you Mike and Maggi. :)
A while ago I made a raised bed for my seedlings (the oldest only one leaf, this is their second year), and planted them just as a clump without the pot, so it is good to know that they can grow there longer, and I don't need to worry about pricking out the seedlings.
T.rivale which has germinated a month ago is still inside, and I will have to think where I will plant that clump in the summer. I'll baby them for now. :)

I've been waiting 8 long years for my Purple Hearts to get purple - I better give up :(

Two more trilliums photographed last evening, t.albidum & grandiflorum.
The t. albidum originally came from Keith Wiley as a single stem about 5 years ago.
-
T albidum is a favourite of mine because of its fabulous scent of roses - been smelling it today. :)
-
Yes I love it too Anne, I'm cross pollinating the albidum pictured with the large flowered kurabayashii .......hopefully to get some pinky coloured ones. I have young plants from a previous cross showing varying shades but not the pink I'm looking for.
-
I did that, and I'm not pleased with the colour that resulted.
Here are a few of my Trillium albidum x kurabayashi.
-
I see what you mean, Diane - those are a tad "muddy".
With first generation ( F1) hybrids there can be some odd colours -for instance at the F1 examples of Crocus x gotoburgensis - I found them rather odd but the subsequent generations are more attractive.
This is something recognised in hybridisation, I think. So perhaps further crossing is called for for those wishing to pursue this. What is a few extra years between friends? ;)
-
T.erectum
T.pusillum
T.grandiflorum
-

I did T. kurabayashii x albidum and either I bombed at the cross or ? There just doesn't seem to be much difference if any from my T. kurabayashii. :-\ Two finally bloomed this year. Seed sown in 2008.
So perhaps further crossing is called for for those wishing to pursue this. What is a few extra years between friends? ;)
So I'm going to try again next year......

Ashley it's amazing how the slugs and snails can read the price tag. Either that or there is a correlation between rarity and taste ;). Over the last couple of weeks I have been waging war but they still come :-\

Agreed Anne. Here is the one I left behind when I moved after 41 years. Don't think the Trillium was quite that old. I tried to count the flowers and gave it up as impossible after 100+. The replacement seedling in my new garden has 2 flowers. I won't live long enough to see it match its parent!
-
Superb, Maureen. What a lovely scent there must have been.
-
A couple of Trillium flowering at the moment.
Trillium pusillum.
Trillium grandiflorum 'Roseum'.
-
Does Trillium grandiflorum 'Roseum' start out pink? The normal type species starts white but turns pink as the flowers age.

Yes, it is pink from bud stage and the young foliage and the stems have a dark tinge in the best forms too.

Very nice collection of different Trilliums, I liked the white ones most. :)
I'm a little worried about my T.luteum, planted last autumn, because it hasn't come up yet. T.chloropetalum var giganteum is already opening it's flowers and T.parviflorum, also planted last autumn, is on bud. I was hoping that T.luteum would be just later, and that is why it hasn't come up, but in Thorkild's pictures they are all flowering at the same time. :(
Can Trilliums rest one year after planting and then still come up the next year like some bulbs?

Yes I do believe they can jump over a year.

Leena I have the same experience as Ashley here luteum has only just come through while chlorapetalum is finishing and yes I have had some trillium tubers lie dormant in the past but this, if my memory is correct, has occurred after they were moved
-
A nice group of T. stramineum blooming in my garden now. These came from Richard Vagner's former collection; I'm not sure where Richard got them, but they are not native to Richard's old home on Gatlinburg, Tennessee. They come from farther west and south, from south-central Tennessee southward along the Alabama-Mississippi state line.

I'm gratified that they are not only surviving but blooming here in my northern garden in central Indiana.

It seemed strange that it would have died, because I had read that T.luteum is more hardy than T.chloropetalum which has done fine the last two years, so I'll keep an eye on it.

Thorkild,
Your Trilliums are fabulous.
I promised photographs of T. angustipetalum and T. albidum - from our wild populations. I'm sure that I have missed the bloom of T. angustipetalum. Trillium albidum grows farther up the mountain and I still might catch it in bloom this season. The drought and strange weather has caused some of our native plants to bloom much earlier this season.
Anyway, thanks for sharing the photos - everyone.

Ian, now that you mention it, they look more like recurvatum to me, too. I need to go back on the trail and take a closer look. For now, I do agree with you -- probably recurvatum, with the "petiolate" leaves and sepals not visible.
Both sessile and recuvatum are native around here. And I'm getting a bit forgetful....
Best,
Jim
-
What differentiates Trillium grandiflorum Wisconsin form/strain from other forms of this species? Both of these are available from different UK nurseries. I have only seen the "form", which seemed to be smaller in stature than other plants of this species I have grown. Is this a characteristic feature?
-

You were right! :) I noticed T.luteum coming up yesterday. I'm so happy about it, and it is good that it is later if we get late frosts some years. Not this year though, it is going to be +28C tomorrow.
-
Great news Leena - pics please if you can ;D
Its scent may be more noticeable too in such warm weather.
-
I'll smell it when the flower opens, I hope it likes it here and grows well in the future. :)
Here it is now coming up, the plant in the background is Pulmonaria 'Blue Ensign'.
-
T.luteum is now flowering. :) T.chloropetalum is still in flower and so is T.parviflorum bought last autumn from Dryad Nursery. I was expecting it to be smaller but it has a good size flower. :)
I planted T.grandiflorum two years ago and this spring it flowered for the first time. I was expecting it to have bigger flowers, I think they are smallest of all the Trilliums I have now, but it is still very cute. Maybe the flowers get bigger when the plant matures? Does it look like T.grandiflorum?
-
From first flowering to mature plant, Trillium can vary in stature by at least a factor of 2, often more: in my experience.
-
Thank you Brian. :)

Yes, they turn pink as they age.
-
Thank you John. :)
-
They will also turn pink when pollinated. I crossed 2 forms this year, both still white, and the next day they were a good strong clear pink, and not streaky as natural ageing seems to produce.

I have been watching over a nice seedling of Trillium grandiflorum "Jenny Rhodes" that I have grown from seed sent by a kind & generous formist in 2009. Up till now I had hoped for & looked forward to the result being the beautiful six petaled Trillium I have admired on the various galleries on the 'net'. Now I am not so sure - I have read it is not possible to raise this beauty from seed - please tell me all. The foliage [nothing at the moment of course as we are in the early stages of a winter] most definitely looks the same as photographs I have seen of this plant.

So maybe there is hope that mine were pollinated by bees and I will get seeds from them. :)
How easily do different Trilliums hybridize naturally? I have T.parviflorum growing near T.grandiflorum, is it possible that they hybridize?
-
Very few Trillium hybridise naturally or otherwise, except the group that includes erectum. Edna, your "Jenny Rhodes" seedling is looking good. Perhaps it will flower next year?
-
Trillium luteum is still flowering, the picture was taken yesterday. I love this plant, I hope it will increase in the future years.

Question for Trillium aficionados. I've just received seed of four species of Trillium from John Lonsdale. Obviously they are coming out of Summer/Autumn in the USA straight into Winter/Spring here in Australia. Part of me feels that it's probably best to refrigerate them and hold off sowing for 6 months, but on the other hand a lot of reading I'm doing warns against delay when sowing Trilliums to prevent extending their dormancy. I have a fridge which could accommodate seedling trays so the other option is to sown them, cover them with grit and fridge them until the worst of summer is over. Our autumn should give them a warm cycle and then natural winter conditions outdoors would be the second cold cycle, with germinations possible the following spring? Anyone have any comments?
My species are;
underwoodii
maculatum
sulcatum
vaseyi
-
I would take the latter course because you won't only extend their dormancy by not sowing them straightaway but possibly also lose their viability. In the Case's book they mention only T. rivale tolerating dry storage (actually not even in a fridge, so maybe some other species from seasonally dry localities would be more tolerant? Just storing in slightly damp perlite or vermiculite in the fridge until a suitable sowing time might be the best answer). This must be a common problem with woodland seed (eg: jeffersonia, hellebores, epimediums etc.) travelling south from the N. Hemisphere, so presumably quite a few gardeners have experience of it?
-
I agree with Tim, holding back sowing may send the seeds into a deep dormancy (if it doesn't kill them) unless they are kept moist. I don't think any of the species you list would enjoy dry storage.
I think I read that they need 84 days of cold to germinate?? So maybe aim to keep them in the fridge for that long. However, I would prefer to sow them into pots/trays, as this will avoid disturbing them if/when they germinate whilst kept in the fridge (if stored in a damp medium it might then be tricky sowing germinated seeds with a tiny fragile root without damaging them). Then, in theory, your warm autumn and following winter should give them their second chilling and cotyledons above the surface within a year, hopefully.
Keep us posted on how you get on.

I think I read that they need 84 days of cold to germinate??
OK, have dug out my copy of Case, it was research at University of Vermont carried out by Stephie Solt that found that T. grandiflorum required a minimum of 83 days of cold (41oF/5oC) for 75% germination.
...the other option is to sow them, cover them with grit ...
Forgot to say, rather than surface sow and cover with grit, I would also sow them deep, i.e. halfway down the pot, where they will be protected from changes in moisture etc.
In summary, Trillium germination is:
summer/autumn 1: seed experiences mild temperatures
winter/spring 1: cold followed by warming breaks dormancy, radicle emerges and forms rhizome/root and immature cotyledon (which remains underground).
summer/autumn 2: seedling exists on stored energy
winter/spring 2: falling/cold temperatures followed by warming instigate growth with cotyledon expanding to emerge above ground.
It is reported that as well as T. rivale, T. nivale may also tolerate (brief) periods of dry storage.
-
Ian sows trillium quite deep. He would sow now, Jamus and keep as cold as you can. It's the safest way- and probably faster way for you to get them established.
Good luck!
-
Thank you everyone for your rapid response! I know just what to do with them now and I'll get right onto it tomorrow.

I have this feeling that Trillium seed will do what it darned well pleases and will germinate if and when ready, regardless of what one does or doesn't do. Having said that, I'd always sow as fresh as possible so sow now, having maybe stratified by soaking for a day or two first. Two years ago (i.e. seed from the flowering of two years ago) I sowed T. maculatum (in a pot) within 10 minutes of picking the two berries and washing off the seed. It is beginning to germinate yesterday and today! No sign at all of the same plant's seed sown last season, again within minutes of harvest, but in the ground around the parent plant. But T. angustipetalum germinated after 5 years in a dried up pot where I'd thrown it under a hedge, where it became covered in dead foliage and had water sitting on it probably for a couple of years at least. T. grandiflorum from the NH germinated after 7 and 8 years in my vegetable garden, among the lettuce seedlings. It must have been dug and turned in several times, limed, composted, drenched and dried out repeatedly, lived with potatoes, cabbage and carrots over that time but still came eventually. In my own experience, only T. rivale germinates with anything like a "normal" pattern such as with, e.g. narcissus, erythronium, crocus etc. Good luck! ;D

Very interesting Lesley! What adventures you've had with Trilliums. I sowed mine this morning in large flats, two species per tray divided down the middle. There are about a hundred seed of each species so plenty of scope here for luck. I used a very nice potting media, rich in well composted organics and pH adjusted and sterile. It's the very best stuff I have available to me which is saying something. I work in a plant research facility which makes specialised potting media on site to very strict parameters.
I half filled the trays, tamped down, spread the seed carefully one by one, misted them with a spray bottle to wet and then buried under an equal layer of the same mix on top. Both trays are now in a little bar fridge (skillfully negotiated with wife to obtain the use of said fridge). I will pop a thermometer in there tonight and I may slip each tray into a large plastic bag to reduce evaporation. Now we wait! I will set up a reminder to myself to check on them once a month and possibly pull them out on the first of March or something like that, and transfer them to the summer nursery (shady one).

Hi, I am new here.
I live in Belgium and I am busy with making a little picture work about Trilliums.
You can see it on following link http://www.gentians.be/index.php?page=exchange (http://www.gentians.be/index.php?page=exchange) . There you need to download a pdf on the subject exchange.
So I am looking after the missing pictures especially pictures of berries. It has been already 2 years that I started this work.
When it is finished it will be a great help to identify Trilliums.
About the Trilliums that I grow in our garden you can see some pictures on our Belgium forum http://www.vrvforum.be/forum/index.php?topic=712.0 (http://www.vrvforum.be/forum/index.php?topic=712.0)

A warm welcome to you Herman!
I have really enjoyed seeing the photos of the trilliums, thank you. I hope that you will be able to find the "missing" photos from some of the forumists here.
