First Trillium out here is this little T. ovatum forma maculosum - the photo is from Ian's Bulb Log 0917 (http://www.srgc.org.uk/logs/logdir/2017Mar011488369508BULB_LOG_0917.pdf)

I saw that in Ian's blog - just stunning!
It is one I've coveted for a very long time. Very glad to see you're getting seed and you now have babies.
-
Maggi, T. ovatum forma maculosum is very beautiful. I have sown them in 2015, so it is still a long time to wait.
Trillium nivale is enjoying the nice weather.
-
Herman - your T. nivale is beautiful - it is my favourite !
-
My slug eaten lowly single blooming size T. nivale is waiting for some sun (which has been quite lacking here) to open.
Herman - your T. nivale grouping is fabulous. How long have you had them?

Julie, it is about 8 years ago that I planted Trillium nivale on that place.

Trillium rivale, first flower this year.

Julie, it is about 8 years ago that I planted Trillium nivale on that place.
The area you have them planted looks quite sunny and mulched with bark. I would like for mine to spread well like yours, any recommendations?

Julie, they are growing outside in humus rich soil in semi-shade, not too wet. This one stand under branches from a tree (from our neighbour, leaves appear very late), so it is a very cool position in summer and now the Trillium gets a lot of light.
Another plant is standing in a more shading and more acid position and flowers always much later (about a month), the place is also more wet. This plant doesn’t grow as good as the other one, so I now have done a bit tufa among the soil to see if it will grow better.
Once they are settled they dislike removing.
-
Thank you Herman.
Where mine is growing it is only sunny in the morning, by noon it is in the shade of our house. We have been having so much rain everywhere is wet.
I have at least one more seedling and I will try to find a location under a late leafing deciduous tree, making sure the soil is humus rich.

Trillium kurabayashii

Trillium kurabayashii
David, that is early for kurabayashii. Are you sure it is kurabayashii? Here in Belgium just the nose is appearing. On the other hand Trillium chloropetalum var. gigenteum is starting to flower. Anyway it is a beautiful Trillium. I have added the berry of kurabayashii.
-
What's been sold as 'kurabayashii' very often turns out to be 'chloropetalum var. giganteum'. I bought my 'kurabayashii ' plants from a well known nursery in the UK and they turned to be 'chloropetalum var. giganteum' . Someone posted a comment on this forum how you can see whether you have kurabayashii or chloropetalum var. giganteum.
i guess i found a sure and quite easy method to differentiate between Trillium chloropetalum <-> Trillium kurabayashii. i checked the Trillium key in "the flora of north america (http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=133668)" to find remarkable characteristics. according to the key with focus on differences in filaments and ovary, i made a fotocollage to show the differences which should be checked easily by everyone. the legend is in german, but should be understand. the chloropetalum foto was taken of a plant in my garden (wrongly thought to be a kurabayashii), the kurabayashii foto was found in internet. i tried to find a foto of a plant described as taken in the wild in an area where kurabayashii is native (as i remember it was taken in oregon). the kurabayashii foto fits all filament + ovary characteristics from the Trillium key. the main difference is the length of the filament...in chloropetalum the ratio between length of filaments is about the double of the length of the ovary, in kurabayshii the ratio is about equal. the length of the connective (the short appendix after the pollensacs; in kurabayashii absent or very short, in chloropetalum about 1,5 mm) could be a second characteristic as an addition to the main difference of the filament-ovary-ratio.

Today I have taken some pictures from Trillium chloropetalum var. giganteum

Hi
My Trillium chloropetalum giganteum is flowering much earlier than in previous years. Picture taken this afternoon. Been a mild winter in Stirling, but rain, rain and more rain. Today was the first dry day for ages.

Steve, beautiful Trilliums! If you can spare some seeds of the dark Trillium rivale and Trillium simile Purple Haze I am always interested.
-
Any suggestions about what is wrong with my trilliums (probably chloropetalum). They have been rotting and turning to slime. It became worse after 3 days of constant rain last week, and is affecting only my chloropetalums. All my other species seem healthy. Could it be botrytis? Should I destroy all affeccted plants? Help!

Trillium smut? Urocystis trillii...you can treat it with a fungicide.
-
Thanks for this suggestion, Wim, I have now googled it for photos and it does seem a possibility. I will send off samples to the RHS for testing tomorrow. Bad news for my trillium collection if it is that.

Such a gorgeous foliage on T. decumbens and decipiens - worth growing just for that.

Those are all beautiful Steve. As gabriela says, fantastic foliage too.

I couldn't agree more with Gabriela, such beautiful foliage!
All Trilliums are so beautiful, and Steve's pictures are so stunning.
Looking at Herman's pictures I'm beginning to think that my T.parviflorum (they are not yet up here) is not T.parviflorum, because it has bigger flowers. Perhaps it is T.album. I will post pictures of it in May when it usually flowers.
-
Leena to be sure you need to wait for the berries (pictures from 2013).
-
Thank you Herman, I will try to remember that!
My T.parviflorum did make a seed pod the first summer but last summer it didn't. I hope it has now grown stronger and also produces seeds. From the first seed pod I got two seeds which also germinated last summer.

As WimB said, it is possibly Urocystis trilli and smut is very distinctive - discussion in 2010 on SRGC

Thank you, Julie, I had found the 2010 trillium thread. I can't get your other link to work, it takes me to a signing in thing on gmail. Could you please post it again?
I have sent a sample off to the RHS and would expect a reply in a couple of weeks. I will report back then. In the meantime, my paris quadrifolia are not looking as good as usual.....
-
I have just received a reply from the RHS advice service, having sent them a sample of diseased trillium. Good news and bad, I think. Here is what they said:
"Thank you for your enquiry to RHS Gardening Advice.
Your Trillium is not infected with trillium smut. Smuts develop within the plant, producing a mass of black spores which burst out of splits in the plant surface. On Trillium the smut caused by Urocystis trillii grows mainly within the stems.
The fungus causing the disease you have observed on your plants is a species of Colletotrichum. This causes black spotting on leaves. It is known in the USA and has been observed on Trilliums in the UK.
Cultural control methods should include:
avoiding overhead watering
promoting good air circulation
not handling wet plants
controlling pests if needed
separating diseased and healthy plants - avoid touching healthy plants with hands, gloves or tools that have been near diseased plants
pruning out the worst-affected leaves
clearing up fallen leaf litter
good horticultural care - appropriate feeding and watering etc.
There are no specific fungicides tested for use on trilliums. The fungicides tebuconazole (Bayer Fungus Fighter Concentrate), tebuconazole with trifloxystrobin (Bayer Fungus Fighter Plus), and triticonazole (Scotts Fungus Clear Ultra and Scotts Fungus Clear Ultra Gun) are approved for use against various fungal diseases on ornamental plants and could be used, but there is no specific information on their efficacy and no claims are made by the manufacturers for control of this particular disease. If the decision is made to try one of these, a few plants should be sprayed first to test whether the fungicide has any damaging effects on trilliums."
I haven't decided whether to spray with fungicide. I am not keen to use chemicals in the garden, but on the other hand, I do have quite a lot of trilliums which I do not want to lose. Perhaps some of the trillium growers here could offer their advice? I wonder how the fungus arrived? Did I buy an infected plant? (The plants which are showing signs of infection were grown from seed here in my garden, apart from the original plant, given to me 10 years ago by a friend). Does this fungus spread with wind and rain, like potato blight?
-
Trillium hyb. chloropetalum or angustipetalum?
This one has very striking leaves! Please, show a pic of it when in flower!

Mariette, Here is a picture of this Trillium

Thank You, Thorkild - a really striking plant! If You´d like to swap seed, I´ve pollinated this chance seedling, either Tr. erectum or an erectum -flexipes hybrid with similar ones.

Sorry about the link that didn't work. I haven't been able to find the document online as the link on the pdf goes to a page that has been changed.
It basically says all the same information you received from RHS advice service on the fungus Colletotrichum. Although, the OSU plant clinic report's very top recommendation said "The fungus sporulates in infected tissue, so it is best to remove and destroy all diseased plants." Then followed by "If you don’t want to do that (understandably), it may be possible to dig them, clean them of all soil and debris, remove any diseased tissues (roots included) and replant them in another part of the garden. A dip in a disinfectant such as a weak bleach solution might help also, but has the potential to harm the plant, and cannot be recommended as it is not a registered treatment."
I'm fairly certain the fungus does spread like potato blight, based on the "sporulates in infected tissue" and other information I've read online.
Wishing you the best of luck.
-
Thanks, Julie, I'm going to put on disposable gloves and clean up all the diseases bits. I am less keen to dig up the roots but I will try this with one clump and see how I get on.

Trillium identification
I would be grateful for any advice in naming this Eastern sessile Trillium which I bought as Trillium discolor. It is clearly not a discolor. I thought it might be T.cuneatum but I'm really not sure.
Any suggestions?

Steve can you take a picture from the ovary and stamens? Is there any odor?
-
Many thanks Herman.
The plant has no scent.
The light levels are poor at this time in the evening but I've taken a few images of the floral parts. I had to peel the stamens off the stigma.
The stamens clasped around the ovary: (https://c1.staticflickr.com/3/2904/33920488682_c2f3462629_o_d.jpg)

-
Many thanks Herman.
The plant has no scent.
Steve, I think it is Trillium reliquum.
-
Many thanks Herman.
There are two features which I thought might go against this being reliquum. Firstly this plant has a fairly tall straight stem and is not semi-decumbent. Secondly the connective tissue does not extend significantly beyond the pollen sacs (it does in reliquum creating a beak-like effect) -see: https://commons.m.wikimedia.org/wiki/File:Endangered_trillium_reliquum_relict_trillium_anthers.jpg
-
Steve, that picture on the link seems to me more Trillium lancifolium. Here are some pictures and details from Trillium cuneatum in our garden. Petals are longer then on your plant and stamens are more erect. (square on the paper are 2mm)
-
Many thanks Herman.
I grow both T. reliquum and T. lancifolium and they look different to the mystery Trillium.
Here is a picture of my T. reliquum. It has the typical "S" -shaped stalk which makes it semi-decumbent.
(https://c1.staticflickr.com/3/2936/33259926784_7035847cf7_o_d.jpg)
T. lancifolium has a different profile with long narrow leaves creating a propellor effect:

-
Steve, I always thought that the S-shape was typical for Trillium decumbens.
I meant the link to wikipedia picture seams to be lancifolium instead of reliquum.
You probably know the website from J. Lonsdale http://www.edgewoodgardens.net/Plants_album/The%20Plants%20-%20%20Complete%20Collection/Trilliaceae/Trillium/Subgenus%20Phyllantherum/T.%20reliquum/slides/Trillium%20reliquum%200001.html (http://www.edgewoodgardens.net/Plants_album/The%20Plants%20-%20%20Complete%20Collection/Trilliaceae/Trillium/Subgenus%20Phyllantherum/T.%20reliquum/slides/Trillium%20reliquum%200001.html)
There are a lot of pictures from T. reliquum but jou can not see the stem.
If your plant is original from garden seeds it can also be a crossing.
-
Herman, John Lonsdale's website states: "T. reliquum is an almost decumbent plant, the leaves sitting on or just above the forest floor. It is superficially like T. decumbens at first sight but differs in a number of features, particularly its non-pubescent stem. An S-curve in the stem is often quoted as being diagnostic but in my experience this character is not reliable."
My T. reliquum originates from wild seed and is I think quite typical.
-
Steve, at the moment probably the best name for your misnamed Trillium discolor is indeed cuneatum. There is a lot of variation in the flower of cuneatum (see Lonsdale). The future will tell you more when the plant gets older and when you see some seedpots.
Thanks for the interesting discussion. More people should be interested in Trillium.
People who have the opportunity to see Trillium in the wild should take more pictures of the inside of the flower and put them on the forum that would be a great help for identification of plants that are for sale.
Two weeks ago, I found following plant on a market under the name T. ovatum, to me it looks more Trillium ovatum forma hibbersonii. I will see what happens when the plant is getting older. I hope it stays so little, it is nice pink, but I don't know the colour when it started to flower.

-
Thanks Herman, my plant was bought from Yuzawa Engei nursery in Japan. Paul Christian's image is of one of the original plants from Nemuro in Hokkaido but what he was selling were seed-raised plants from this strain -possibly from the same commercial source as my plant. Sadly few of these can match the beauty of the original plants found in the wild at Nemuro.
-
Steve - Sent this id thread on to Trillium friend in BC, he responded this afternoon:
"John, an easy one, it corresponds to T. cuneatum and keyed out in Trilliums by Case and Case. Features: anthers dehiscing latrorsely (hey, I didn’t make up this name), connectives not elongated beyond anther sacs, petals quite large and broad. I have grown it, but not noticed this year. By the way my plants of flexipes x hibbersonii have flowered well this year and I have decided that they definitely are hybrids being nicely intermediate in size. Good germination of seeds of flexipes x camschtcense, will wait to see whether these are indeed hybrids. Joe"

Hello John
I'm very keen to see some photos of the hybrids if that is possible please ?.
No flowering here of course at this end of the planet .....Just seed on the move such as mixed 'home' Pseudotrillium rivale harvested fresh, sown immediately about 12 weeks ago currently germinating underground .

Many thanks John. I've changed the label to cuneatum.

Trillium apetalon and Trillium grandiflorum
-
Perhaps anyone can tell me if this is Trillium albidum and what colour the ovary of white Trillium chloropetalum has?
This plant was raised from seed of friends, who grow two trillium they bought as albidum and sessile Rubrum. Many of the seedlings flower white, but not with a green ovary. This one looks more like Trillium albidum, as far as I know.
-
In other white flowered seedlings the ovaries show variations indicating hybrid origin.
-
Another one.
-
Mariette, when My T.chlorpetalum giganteum 'Album' flowers in May, I will look and compare it with your plant. In last years pictures I can't see the ovary well.
Last summer I received two small bulbs of Trillium nivale, and I planted them in the ground. I have been looking for them all April, and now finally the ground has melted in that bed, and today I saw them come up and the other one has a bud! :) I never expected them to flower so soon, so young. And I am so happy that they had survived a difficult winter. It is small and so pretty!

And I am so happy that they had survived a difficult winter. It is small and so pretty!
Thank You, Leena! It´s good to see that Tr. nivale is doing well in Your garden!
Most of my first acquisitions of trillium were distroyed by slugs, thats why I raise as many as possible from seed to select more robust strains. It worked quite well for me, but unfortunately many trilliums raised from seed harvested in gardens are either hybrids or turn out to be wrongly named. Nevertheless, there are some attractive plants among them. I rely on the book of Case & Case to determine the species, but unfortunately it doesn´t always mention the colour of the ovary of white forms.

Spent a long time today untangling the roots of a very congested pot of Trillium rivale seedlings. The pot was sown in late November 2011 and germinated in March 2013. A few flowered last year there was mass flowering this year. I counted at least 75 rhizomes.
April 1st
Today

Wim, I love the leaves of T.discolor, perfect with the flower.
What a clump of seedlings, Roma, congratulations.
Like Mariette, I try to raise more plants from seeds so that I would get some which are suitable to my climate. Winter 2015-16 was very cold with a little snow cover, and I lost many young seedlings, also T.rivale (but now I have new plants germinated from seed ex seeds :)). Since then I try to keep the seedlings in pots until they are older (three years old T.chloropetalum seedlings survived in the ground), but the trouble is that I have only root cellar to keep the seedlings, and they start to grow too early there, in March, when I can't take the outside yet, and inside the house it is too warm for them.
Case's book is good, I got it as a Christmas present last year. :)

Some trillium in the garden
Trillium sessile -NW Ohio
trillium sessile - Indiana from Boots Case' childhood home
T viridescens- ex Case
t viride- SE MO with T recurvatum in back
T recurvatum shayei

Trillium maculatum
T cuneatum
Some yellow trillium forms- maculatum luteum and discolour
Trillium recumbens
Last one -i dont recall name- not T decipens?
-
Rimmer, I believe that decipiens should have a longer stem.
Here is Trillium stamineum.

Now you are making us all jealous, Steve!
Beautiful flower.
-
Oh my!

T. decipiens would have a horizontal rhizome.

That one looks a lot like a sessile type I have (that is not T. sessile), but it does not have horizontal rhizomes. This one doesn't key out nicely to any species; I believe it must be a hybrid.

Trillium undulatum
Steve, a very beautiful Trillium undulatum. This one is very difficult in Belgium.

Herman, I have a warm, fairly sheltered, sloped south-facing garden. My garden is too hot for undulatum so I grow it in a pot kept in a shade frame. The compost is a free-draining mix of silica sand, granite grit and Scots Pine needles/leaf mould to which I add some finely chopped sphagnum moss. This mix is VERY acidic. I only water with rainwater/RO (reverse osmosis treated tap-water) water and add 10ml cider vinegar to 1L every 2nd/3rd watering.
The plant is seed-raised from Canadian seed bought on eBay some years back. Germination was poor and the seedlings dwindled over the following years as I didn't know what conditions they liked. Eventually I was left with one sickly young plant. I gleaned some info from the internet on how to grow undulatum and so altered the compost and watered as above; the plant has since gone from strength to strength. Though still a small plant it has two growths this year.
I am no expert but I think that the important issues are a free-draining mix and maintaining a very acidic compost (pH <4.5). A very acid compost limits decomposition of the organic content in the mix which helps preserve the compost structure/free drainage and suppresses pathogenic fungi.
Of course it is possible that all of the above is nonsense and I have simply enjoyed beginner's luck. ;)

Thank you Steve. At the moment I have one seedling, I hope there will appear more, to try.

Beautiful pictures Steve!
Tr. lanceolatum is that the same as Tr. lancifolium?
-
Steve, I don´t know at what to marvel more - Your exquisite trilliums or Your outstanding pictures!

Whoops!
You are of course correct Herman, it should be lancifolium. I've changed my entry.

Trillium cuneatum ex Don Armstrong
Steve - For what's worth T. undulatum is native here ad grows in great abundance down on my land in the fog belt, there it grows in shade and full sun with Clintonia, Cornus canadensis, Medeola etc. When I dig one I'm always surprised as the stems come up through 6-10" of rather open forest duff with moss growing atop. The bulb sits way down there on rather stiff wet mud and the roots are in the seemingly airless mud. I can hardly imgine you are too hot to grow it unless your rainfall is too low - here 56"/yr. and about 62" in the fog belt. It's a stinker to grow in gardens here!

I'd say both are excellent.

Pictured below is a Trillium rivale from my garden today. It hasn't shown any signs of dying back yet, is this normal please?
-
Not sure what that is, David, but it's not a trillium I don't think!
:P
-
Oh b****r!!!!!!!!!!! I'll have to do some excavating tomorrow. Think I know what it is though which is growing a couple of feet away from my 'Trillium'
-
Yup!

Trillium seeds.
Sometimes I hear that Trillium seeds do not germinate well. My experience with T. Seed is that they should be sown before December, if you get T. seeds in February, it's late in my opinion.
