It is more easy to put the Trillium's in topic Trillium 2020.
Trillium nivale suffers this year a lot from the rain.
Trillium chloropetalum var. giganteum is doing quiet well.
-
Trillium chloropetalum var. giganteum is going on well. Trillium nivale doesn't flower good this year.
Trillium ovatum between Hepatica nobilis 'Rubra'.
-
An impressing range already, Herman!
The first one to flower in my borders is this one with green flowers., Trillium chloropetalum or hybrid.

Mariette, it is a nice Trillium. How does it smell? Trillium chloropetalum smells like a rose. Can you take a picture of the ovary and later from the berry?

it's a very nice Trillium Mariette !

It is very nice indeed. :)

News from Aaron Floden of an open access article (YAY!!) on Trillium hibbersonii
Trillium hibbersonii (Melanthiaceae), a phylogenetically distinct species from western North America
DARLENE M. O’NEILL, SUSAN B. FARMER, AARON FLODEN, JAYNE LAMPLEY, EDWARD E. SCHILLING
https://www.mapress.com/j/pt/article/view/phytotaxa.436.2.9?fbclid=IwAR093ZWuhM7ZuTf1tn5TgTGTlT-LUZR5zTFI7dlwQ13ieIpqSlcbM9Lq48g (https://www.mapress.com/j/pt/article/view/phytotaxa.436.2.9?fbclid=IwAR093ZWuhM7ZuTf1tn5TgTGTlT-LUZR5zTFI7dlwQ13ieIpqSlcbM9Lq48g)
Abstract
Trillium Linnaeus (1753: 339) species have a reputation for being difficult to distinguish from one another, both on morphological (e.g. Freeman 1985, Schilling et al. 2019) and initial studies with standard plastid markers (Osaloo et al. 1999). Thus, the species that is sister to the rest of the Parideae, Pseudotrillium rivale (Watson 1885: 378) Farmer (2002: 687), was only recognized to be distinctive after DNA sequence data became available (Farmer & Schilling 2002). In the somewhat similar case discussed here, an entity that was considered to be only a form or variety of one species, T. ovatum Pursh (1803: 216), has turned out to be so genetically distinct that it is not even placed in the same clade as T. ovatum (Farmer 2006, Lampley et al. unpubl.).

Thanks Maggi and Aaron.
My few plants have been informed of their elevation in the (scientific) world ;)
Seedlings are just appearing too.

Thank You, Herman, Véronique and Leena! It´s a trillium I like very much, raised from seed of the late Wolfgang Reich. He crossed several species like albidum and red chloropetalum and used the hybrids achieved to breed on with other selections. I don´t think my seedling is pure Trillium chloropetalum, yet more knowledgeable people may judge. The odour is rather disagreeable, I´d say. Unfortunately, it´s no rapid grower, but I was able to share seed the last two years.
Here are two closeups, sorry for the poor quality of the pics.

Mariette, the stamens are bent outwards, that is not normal for chloropetalum. So I suggest that it is a hybrid but with what? Stamens bending outwards is more something for Trillium flexipes, but I don't think that, that is possible. Maybe it is a crossing with Trillium parviflorum.
-
Sorry, Herman, I´m afraid that´s an artificial effect, as I bent petals and stamens slightly outwards to show the ovary, too. As far as I learnt from Wolfgang Reich´s list he hybridized only among the sessile group. If of interest, I may take another pic of an undisturbed flower, they should be more open with the weather so fine now.
Wolfgang Reich offered also seed of greenish Trillium albidum-hybrid, I guess the green colour was recessively born in his red chloropetalum.

I'm anything but a Trillium specialist ;D, but this Trillium rivale 'Purple heart' does well for me in the peatbed. Not a fast grower though, this is a 5 year old plant.

I spotted a nice clump of Pseudotrillium rivale seedlings in the garden taking advantage of the sunshine. One is likely a seedling off of 'Purple Heart'.
Trillium kurabayashi seeds freely in the garden.

Trillium all germinate right now? ?
is T grandiflora later? my only seedling from last year has not yet reappeared .. :(
I have about twenty seedling pots of all ages (0-5 years) which still do not show seedlings ...
the Trillium rivale are beautiful ..

Hi Véronique, they should be germinating / shooting around now.... hopefully! Still a decent chance it will come up. Maybe a good idea to put out some slug pellets just in case.

Herman,
Lovely big clumps of cuneatum and pusillum. Do you find that your pusillum increases vegetatively? I have had a couple of plants for about 8 - 10 years and they have not increased. I am patiently trying to build up a nice group from seed.

Carolyn, yes they increase vegetatively. This Trillium stands there for about 9 years in a humus rich soil.

Trillium hibbersonii has finally received official recognition.

Trillium hibbersonii was officially described as a new species.
Interesting is the finding that T. hibbersonii ribosomal DNA is closer to T. erectum
than to T. ovatum.

Hello Herman, this is a plant I bought late in 2016 and it flowered for the first time in 2019, but you may remember that the flower was fasciated. Much better now though. I'll keep an eye on it and see if it produces any seed.

Could this also mean than T.hibbersonii is as hardy as T.erectum?
I have full pot of T.hibbersonii seedlings which germinated last spring :). I'm wondering if I could plant them outside this year or still keep in pot just in case the next winter will be a cold one..

Leena, I don't think they are as hardy as erectum. Trillium erectum grows very well in our garden but hibbersonii doesn't. I would keep them in pot till they are flowering size and then put a part in the garden. If the pot is a small one then put the whole clump in a bigger pot.
A few years ago I had a flower in the garden and later some seedlings but they vanished!

All looking very well, Mike. Great to see the variation in the seedlings - something which always interests me. Seems there are only a few with the darkest colour of the parent - but it also looks like those ones have less well -marked leaves than the parent, is that right? Quite a few of the others have maintained the good leaf colours, I see. So much to see and learn from plants, isn't there?
-
Maggie some seedlings in the past have had a lot of mixed shades & even bicolours. I have noticed that the paler the colour the less pronounced the leaf markings are.
The original plants were grown from seed over 30 years ago & the seed came from Phil & Gwen Phillips's garden. They also used to have pale pink seedlings appear.
Growing from seed is wonderful, you never know what might appear.

A lovely diversity Mike, and pristine.

Beautiful Trilliums, Claire. Pseudotrillium rivale has been difficult for me, it has died during winters twice when I have tried it. Sadly I lost also seedlings from your seeds when I planted them outside. Now I have some which are from seed ex seeds from year ago, and I will try to grow them in pot.
T.nivale has been very hardy here. These are seedlings which were sown in 2016 and planted out last summer, and now they are going to flower for the first time.
-
Hello, Leena. I'm sorry you lost the rivale seedlings. It's interesting that RIVALE seeds around my garden with no problems, but I can't grow NIVALE. It is a slug magnet. Yours look lovely.
...Claire
-
Thank you Claire. :) Slugs are luckily not awake yet, because of cold nights. I use a lot of dry leaves for winter protection, so that could also give shelter to slugs but so far there hasn't been any damage. Knock on wood..

Ashley, my Trilliums stand in rich humus soil. Some Trilliums like a bit lime so I added some tufa in the soil. The clump sometimes consist of several seedlings in one group.
Feeding in March and July: NPK (Mg) 6-4-10 (2) and NK 2-20

This year has been the best for trilliums. I gave them some fertilizer a while ago, something I rarely do. It seems to have paid off.

Claire, your double T.grandiflorum is so big! Maybe I need to feed mine also more. It has had two flowers now for three years, and I don't think there are more coming this year either.
Trillium nivale seedlings, they are small but I like them a lot. :) They came up in the beginning of April and they are still flowering. It's been relatively cold April and they love it (for me the freezing nights could stop now, I worry and cover my T.chloropetalum plants every night because they are already soon opening their flowers and I have read that they are not so cold tolerant, so far so good).

I have sowed this small Trillium from 2014 seed ex seeds as T.sessile and it is flowering now for the first time. This is like a mini version of T.chloropetalum (more than half the size), small but sturdy with thick leaves and thick petals.
The third picture is my bought T.sessile, which is even smaller plant and the leaves are quite thin, and flower is smaller when it opens.
What do you think? Are both these plants T.sessile?
The last picture is T.chloropetalum grown from Dryad bulbs seeds, and in the left there is T.chloropetalum grown from seed ex seeds.

Nice trilliums Leena. Your third photo reminds me of luteum, but perhaps experts here will give a more informed opinion.

Beautiful Trilliums, Steve.
Here they have suffered a lot from dry wind? The ground is also very dry, the last month there has been too little rain.
-
I keep coming back to look at Steve's beautiful Trilliums, especially T.decumbens is so perfect (and the picture of it). :)
-
Many thanks Leena.
I grow decumbens, discolor, reliquum, tennesseensis and underwoodii in a cold frame which has a thermostatically controlled subsoil heating cable. They can tolerate the cold of most Scottish winters but strong wind and excessive winter wet is too much for them. Having said that Cyril grows decumbens on a raised bed in the open garden and his garden is colder than mine.
Trillium vaseyi -huge flowers, it’s a pity that they hang below the leaves.

Great trilliums as always, Steve. I love the details of the veining on flexipes.
-
Steve. Not only are your Trilliums splendid but your labels are also very attractive and really add to their presentation.
Edna
-
That’s cos my writing is atrocious and illegible! ;)
Black plastic T labels are available on eBay. The labels are printed using a Brother label printer. I bought mine after watching an electrician (who did some re-wiring for us) use one to carefully label various wires and terminal boxes. The labels have resisted the worst of the Scottish weather so far but will probably become brittle due to the effects of UV light on plastic over time.
-
I always marvel at all of Steve's photographs. Each one is a wonderful blend of composition and botanical detail. These details are often important in identification, and for me, it is more often the intricacies in plants that excite me, and I find myself studying my plants as much through detailed photos as I do through physical observation.
------------------------------------
This year I am finding all kinds of trilium seedlings. Not only ones that germinated last season and popping up for the first time now, but I am a little embarrassed to say there are a couple bunches from the year before that I hadn't noticed until now. As you can see, even the second year seedlings are crowded. I wonder if I could separate them in now, in year 3 or year 4?

Yes, you could do that now, Rick.
-
Thanks, Maggi. I hope to get some good photos of second year seedlings.
There certainly must be some good selections of T. cuneatum out there. This is wild collected by a friend on his property in Illinois. He says they grow like weeds! Surrounded by wild Claytonia virginica from northern Indiana. Started back in 1992, I now have plenty to munch on. ;D The non-flowering plants are already turning yellow. Just as Ian says, flowering (and seeding) bulb plants stay green longer.
[attachimg=1]
This is a selection of T. sessile, wild from a different part of Illinois. Propagated by my same friend, this one has hardly a spot on the leaves (and very faint at that). He is calling it 'Clear Creek'.
[attachimg=2]
-
Beautiful and interesting pictures from all. I am glad that Rick just posted few T. sessile pictures showing its variability, which I understand it is even greater in the wild.
I had the chance to buy in the last 3-4 years non-flowering 3 years-old T. luteum. Gradually when they started to flower I realized that I have a small collection, besides T. luteum: T. cuneatum (which I shown before), T. flexipes and this year T. sessile!
T. cuneatum and sessile for someone not familiar with them can be challenging so I took close-up pictures as well. I think Leena asked about it.

Rick, your T.cuneatum and T.sessile look very beautiful in beautiful pictures. :)
Also Gabriela's T.sessile is a very nice colour, I like the golden brown flowers.
I compared the connectives and anthers in my seed grown T.sessile, and they are just like in your picture, so it is a right species. Thank you for taking the picture. :) It is always good to know what I am growing. :)
This is T.parviflorum sown from seed ex seeds and flowering now for the first time. Flower is small, but I like the leaves. Flowers are in proportion to the size of the whole plant.
Second picture is a plant grown as T.kurabayashii. It is vigorous and grows well even here.

It should be sessile Trillium.
Concerning Trillium sessile as "species" then the petals should be shorter see http://edgewoodgardens.net/Plants_album/The%20Plants%20-%20%20Complete%20Collection/Trilliaceae/Trillium/Subgenus%20Phyllantherum/T.%20sessile/slides/Trillium%20sessile%200001.html (http://edgewoodgardens.net/Plants_album/The%20Plants%20-%20%20Complete%20Collection/Trilliaceae/Trillium/Subgenus%20Phyllantherum/T.%20sessile/slides/Trillium%20sessile%200001.html)
It is the same with Gentiana acaulis, you have that name as a group of plants and also as species
-
Gabriela, concerning Trillium flexipes, the ovary and anthers should be creamy white instead of yellow. Maybe it is a hybrid?

Thanks Herman. There is great variability in T. sessile, and in general in the group of sessile Trilliums.
Pictures taken in the wild, in their natural habitat are best to asses this. Here's a good link.
https://www.marylandbiodiversity.com/viewSpecies.php?species=1813 (https://www.marylandbiodiversity.com/viewSpecies.php?species=1813)
I don't really understood what you mean by "it should be sessile Trillium" - the ones shown in bud? They flower and are T. luteum (to the left of the image). I tried to separate the T luteum from the others but there were not flowering last year.
[attachimg=1]
-
Gabriela, concerning Trillium flexipes, the ovary and anthers should be creamy white instead of yellow. Maybe it is a hybrid?
It all depends on the light, camera and if you take pictures when the flowers are recently open. I will post another picture taken when the flower opens.
Even so, if you would look in the FNA keys, it is all in within the species variability. There are hybrids possible but I don't think it is the case here. We should never ascertain species based only on the pictures posted on-line.

I don't really understood what you mean by "it should be sessile Trillium" - the ones shown in bud? They flower and are T. luteum (to the left of the image). I tried to separate the T luteum from the others but there were not flowering last year.
Gabriela with sessile Trillium I meant the sessile group (the other group is the pedicellate one). In the Gentiana acaulis group there are different species: angustifolia, clusii, acaulis ... But Gentiana acaulis as species is something that is many times used wrong.
I have added my Trillium sessile, the flowers are more compact as the other Trilliums of the sessile group.

Very nice trilliums Gabriela. It is borderline hardy in Saskatoon,Canada.
I have a Trillium kamschatcum which is planted near the foundation of the house. Flowered two weeks ago. Nice plant but not very nice picture.
-
Hi Gabriela -I forgot to add that I have 3 little seedlings of Trillium grandiflorum from your seed I got 3 years ago!!
-
I have grown this Trillium from seed ex as T.erectum hybrids, it was 2013 I think, and now they flower for the first time, both plants have similar flowers. :)
-
Trillium sessile group seedlings. The leftmost is a first year seedling, the others are second year.

Beautiful plants show well even without great pictures Kris :)
I'm glad about your T. grandiflorum seedlings, but why just 3 of them?

Wow! very nice Leena. Maybe not a hybrid and var. album? T. erectum hybridizes indeed with various others, including with T. flexipes shown above.

Herman, your T. sessile specimens are very nice. But I don't think you open the link to see how variable this species can be.
All of them are 'true' T. sessile. It just happened for you to get some with short petals, that's all. Many times we are acquainted only with the forms of certain species grown in the gardens without being aware of their variability.
Screenshoots from Flora of Michigan, there should be no problem since the pictures have the author names. All T. sessile in wild habitats.
I recommend this very accessible on-line searchable flora, there are keys for the species, simpler to use than FNA. https://michiganflora.net/ (https://michiganflora.net/)

I got only three seedlings. But still I am happy. May be the cold winter is the culprit. I tried Trillium grandiflorum plants several times but always failed.

You know how it goes Kris: try again, fail again, fail better :))
How do you keep your seedlings pots Kris, have you tried the method I showed in the blog - by 'planting' them in the ground?
It leads to great results with minimal effort for many other species which need to spent 2-3 years in the same pot, not just Trillium.

Gabriela, I have seen the link, but I was not convinced that they all are true Trillium sessile, therefore there should be DNA research. Also in the wild there will be crossings with different sessile forms just as they do in the garden. I presume that there are different sessile forms in Michigan.

Thanks Gabriela. I don't know why the seeds were named hybrid, but I guess for a reason, and if the mother was a hybrid, then the seedlings must be, too. I have been wondering what is a difference with var album and a hybrid, but because I don't have var album, I can't compare. These my plants came up later than normal red T.erectum and started to flower at least two weeks later, maybe almost three weeks later. They don't grow in the same bed, but I wouldn't have thought the bed where these white ones are was any colder than others.

The flower from Trillium chloropetalum var. giganteum is very impressive, but also the berry.
-
Here Trillium berries are not quite yet ripe. This T.chloropetalum 'Rubrum' has only one seed pod ripening even though it had many flowers. I have been wondering all summer about the smaller leaves at the base of the big plant. They look like seedling leaves, what do you think? Or can they come up from the bigger rhizome? Last year I got seeds from this plant, but previous year someone stole the seeds before I realized they were ready. This plant flowered for the first time 2015.
Another question, what do I do now? Should I dig it up and divide?

Leena, I would wait and see what the flowers will be. If it is the same colour then you have a bigger clump if not you can still separate them. If it are seedlings then they are older then two years. When the tip of the rhizome has been damaged then you get more shoots at the same rhizome. If you want to be sure, remove a bit soil and see of there are different rhizomes. Here most of the leaves are already disappeared because of the dry, hot (30°C in shade) summer.
-
Herman, thank you! :) I will wait for the flowers, and you are right that the leaves look more than two years old. It is possible that there had been seeds earlier but I'm almost sure if there had been seeds, I would have taken them to sow myself, because I'm still at the stage where try to have more trilliums in the garden. :)

This Trillium sp. is the only one we've been able to grow and re-flower, though it took 10 years to get the first bloom and it doesn't flower every year. The first pic was taken 2 days earlier.
I presume it's a form of Trillium chloropetalum but stand to be corrected
cheers

Fermi, can you take a picture inside the flower to see the anther sacs and the ovary.
Description F. W. Case: Stamens erect, 17-26 mm long filament widest at base about 4 mm long; anther sacs introrse; connectives purple, prolonged about 1 mm beyond anther sac.
The leaves are right. But the sepals are so dark?

Hi Herman,
I can't see the ovary clearly in this pic but it may make things clearer - the flower may not be fully mature yet
cheers

Hi Fermi,
Stamens look right, I would also give it the name Trillium chloropetalum.
Greetings,
Herman

Thanks, Herman,
I'll go with that
