Trillium nivale
Wow, Herman, that is the biggest clump of T. nivale in the ground I have ever seen! Do you have some special secret? ;)

Peppa, they are growing 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.
Once they are settled they dislike removing.

In my area, slugs destroy Trillium nivale before it gets a chance to grow, even in pots. They mostly leave other trilliums alone.
Pseudotrillium rivale has seeded around the garden on its own. I still keep some in pots and enjoy the many forms. This one has smaller flowers and nice leaf markings.

I bought a single start of Trillium pusillum many years ago. The clump has expanded every year. I've tried to dig some to share and discovered the roots are very, very deep.

Lovely Trilliums Claire!

Hello there,
Its good to see such excellent clumps of Trillium nivale and that is a large clump of Trillium pusilum. Trillium nivale is one I can't seem to grow. Perhaps its not so hardy with me in Inverness. I do grow Trillium rivale as well as quite a few others but have never had success with nivale. Once I work out how to post pictures I will add a few taken last year. The only one that is in growth at the moment is Trillium chloropetalum rubrum.

Hi there,
I apologise if the pictures don't appear. Not exactly sure how to post pictures but here goes.
A few pics of trillium . First is T.rivale, the second is a hybrid grown from T. chloropetalum albidum with deep lavender suffused flowers. Its also highly scented and so far seems to be bulking up well. Hope to be able to divide it this year. I tried last year to remove the centre of the crown of a side shoot to encourage young plants and so far seems to be working.

I think it's interesting how the shapes of T. rivale vary. Alasdair's are pointed triangles; I have some similar. Some have an ogee shape, and some are almost round.
I loved the T. chloropetalum albidum.

Trillium rivale does vary in leaf and flower shape and colour, Perhaps there is a bit of hybridising within the species. I have some from seed that have slightly rounded flowers as well similar to nivale. I suppose over the years of being grown in cultivation they may have hybridised. This year they are very late in appearing. Probably due to the cold dry weather we are haaving. I usually get Chloropetalum rubrum first and then T.sulcatum ,erectum and chloropetalum album/albidum with luteum around the same time. Trillium grandiflorum is next but the double form is always 2 weeks later. The last of all is grandiflorum roseum which with me tends to be at least 2 weeks after the double. Can't find my hibbersonii but I am living in hope it will appear.
We have a bed in the garden that is now full of T. chloropetalum rubrum that are self seeding around like mad. Its a bed that doesn't require much weeding so I think they are being able to establish themselves without disturbance.

A few Trillium rivale starting to flower.

All beautiful. Do you still grow those amazing deep pink forms you showed previously Michael?
-
Yes, I should have a few but they are only starting to flower, very late this year.

Thanks Herman for your tip! I have grown nivale from seed and still only have a few seedlings, so I will baby them in pots for the time being. Hopefully they will flower before too long. :)

Rudi, are you sure it is hibbersonii? It seems to me more a form of rivale.

Herman, my knowledge about Trilliums is rather limited. I got the seeds with this name from a friend who
collected them on Vancouver Island.

It looks like T. rivale to me too - rather a nice one, with the pink markings.
-
Six years after sowing, Trillium kurabayashii flowers for the first time. Fortunately, it appears to be the true species - hereabouts, Tr. chloropetalum or hybrids are usually sold as Tr. kurabayashii.
-
Herman, my knowledge about Trilliums is rather limited. I got the seeds with this name from a friend who

Vancouver Island - if the seeds were wild collected, then it's T. ovatum forma hibbersonii, which is found there.
T. rivale is not found there - its distribution is the Siskiyou Mountains, SW Oregon, Klamath Mountain Ranges.
-
My trillium hibbersonii is just through the ground but is usually much shorter in flower (almost stemless). I have it in a North facing deep raised bed. Perhaps it is taller as its in a pot perhaps in an alpine house. Will post a picture of the plant I call hibbersonii when it decides to flower. Its always later due to being cool and North facing

Fresh seed seems to be best. We've had great germination with Trillium seed this year. Fresh fresh seed received thanks to Gabriela and a generous friend in New Zealand.
Pix:
1. Trillium grandiflorum seed ex Gabriela

Was it the chilly but frost-free spring and the frequent heavy rains?
When shall we start too fertilize? Thinking 1/4 strength water soluble.

Trillium undulatum -It’s rooting out of the bottom of its pot but still has only one shoot.

Steve, beautiful Trillium and picture!
-
Steve, that undulatum portrait is absolutely stunning! I hope to collect seed from some wild populations near our home, later this year.
-
Beautiful undulatum, Steve. Well done, too, as it has a reputation for being a bit difficult, so I have read. I bought fresh seed last year - or maybe the year before - I must go out and see if it is showing any signs of life. Do you grow it in composted pine needles - I have seen that recommended somewhere.
-
Many thanks Carolyn!
I grow my plant in a very open mix of Scots Pine needles, ericaceous compost, pine bark, granite grit and pumice. I top dress with Pine needles but until recently hadn’t used any liquid feed. Watering is with rain water, and rain water with 15mls/litre Cider Vinegar alternate waterings. It is kept on the dry side in Winter. So far it has not clumped up at all and so I have started to use 1/4 strength balanced fertiliser. It seems to be self-fertile as last year, after pollinating with a fine paintbrush it set seed.
-
Steve - Wonderful undulatum. I have hundreds on my land so don't attempt to grow it; I can't recall ever seeing offsets or clumps now that you mention it. In fact they seem rather evenly spaced but all solitary. It is the damnedest Trilllium to dig, I went down through about 10 inches of dryish moss and needle duff to find the the bulb sitting atop rock strewn wet mud with roots going down into the mud. That's where it stayed!

17c & sunny, then rain this evening till Saturday

I hope your plant will be OK with fertiliser. I wonder whether the acidic soil in its natural environment is low in fertility? Maybe johnw can tell us?
I haven't managed to locate my T undulatum seeds yet - I have so many pots of seeds, sometimes it gets a bit out of hand....

Trillium nivale in the Minnesota (USA) wild. These are the largest flowers I've seen in a decade. I think they really appreciated the 22 inch (56cm) snowfall we had just 3 weeks ago.

Ooh! Be still my beating heart!
-
T. nivale is one trillium I can't grow, because the slugs find it as divine as I do!
I have what appears to be a hybrid between T. sulcatum and T. vaseyi. The flowers have tightly recurved petals like vaseyi, but are upright rather than nodding below the bracts. The bed also has hybrids between T. sulcatum and T. flexipes, creating some nice picotees.

-
A very showy plant, Claire! The upright flower is always a great advantage - one of my Trillium erectum hybrids has flowers which dangle from a 5 cm long pedicel - not helpful to enjoy their nice colouring.
-

I agree, very nice flowers!
Also Rick's T.nivale from wild is wonderful. It seems to be a very hardy Trillium, mine has survived now two winters.
I wonder if T.rivale is not so hardy? I have lost all seedlings grown from Claire's T.rivale seeds, and last summer I planted one bought bulb of T.rivale, and there is no sign of it yet. I fear it has also died during winter. It would have been so pretty little Trillium.
-
Regarding Trillium nivale in the wild, you may want to look at this thread of mine:
https://nargs.org/forum/hastings-scientific-and-natural-area-minnesota-usa
Many of you may have already seen it, but some not....
-
Rick, thank you for the link.
It is good to see Trilliums growing in the wild, what kind of habitats they prefer. Though they look fantastic growing in the cliffs, but I loved also a picture of them growing among oak leaves, I could imagine that happening also in my garden in my dreams. :)

Rick, those T. nivale in the wild are wonderful to see. Thank you.
I wonder if T.rivale is not so hardy?
Leena, here this survived -10°C even in pots last winter so should be hardier in the ground under snow. It might be worth trying again.
-
Ashley, I might try it again and it is easy to germinate even from seed ex seeds. I was thinking maybe it doesn't tolerate ground freezing deep for a long time in winter or something like that. Even all T.chloropetalum seedlings have survived here but not T.rivale.

Trillium grandiflorum is 'on display' in Ontario :) It was very hard to select only five pictures; here it is in its usual and not that usual forms.

Gabriela, that is a really exceptional pink form of grandiflorum. After a few years, my three plants of grandiflorum have decided to bloom for the first time. One has disappointingly narrow petals, but perhaps with age, its shape might improve.
-
Gordon, the flowers of very young T. grandiflorum don't always display the full characters of the mature specimens; there is indeed great variability and actually I don't mind the ones with narrow petals. Most in our region are very broad as seen in the pictures.
There are quite a few pinks mixed into the whites population. Of course that they cross pollinate; I dream to find a location just with the pink form of course.
I just planted my 3 years old in the ground, they were too crowded - who knows maybe there us a pink between them :)

Hi all, and apologies for the somewhat beginner’s question , but are there both clumping and non clumping/ offsetting cultivars of T. cuneatum?
-
Michael
I find with most trillium that there are forms that readily form clumps while others that either don't or clump very slowly . Both genetics and growing conditions have an effect.
The main growth bud forms at the tip of the rhizome clumping occurs when secondary growths on the back of the rhizome activate, these are often inhibited by the dominant primary bud and will only activate if the main bud is damaged in some way but in clumping forms they grow in tandem with the main bud.
I have cut the dominant bud, complete with newest roots, off the rhizome - this grows on as normal and the secondary buds on the rest of the rhizome activate. I do this is after the flowers fade and before the leaves die back.
-
Thanks Ian. There was some reference to a certain variety being a non clumping variety. I recently acquired a few rhizomes and hope they will do well- and hopefully clump up. I saw some images what you mentioned, where dormant back shoots could develop when encouraged.
Fingers crossed .

At this point the leaves of Trillium cuneatum 'Don Armstrong' have turned from dark choclate brown to green though the flowers are holding up nicely. Epimedium davidii to the fore.

Trillium cuneatum 'Don Armstrong' has a most pleasingly chunky flower.

Indeed!
These, I think, are more typical. They are from wild stock in Illinois, USA.

What a beauty this form of T. cuneatum.
I have only one plant for now and it's the same like the ones Rick posted; it was bought as T. luteum actually :-\ In the last three years I bought non-flowering size Trillium
lutem which prove to be anything from luteum to cuneatum, and flexipes.
Here's my T. luteum, I love the scent and it stays in bloom for a very long time (comparing with grandiflorum and erectum). With E. stellulatum and P. sieboldii.
[attachimg=1]
-
Rick's T.cuneatum is fantastic. :)
Here is my T.luteum couple of days ago, it does flower for quite a long time. Mine isn't as yellow as Gabriela's lovely plant, though now it is in the end of flowering, it also grows in quite shady place.
-
Hi everyone, I’ve had some very good luck to be able to buy some nice trilliums over the past weeks, including at the Ferny Creek Horticultural Society show. For me, in Australia, these are exciting new additions, though sometime I hope to get a few other species as well.
-
By jove- you've done well there, Michael!
-
Three new Trillium species now join cuneatum, erectum, grandiflorum and luteum.... T kurabiyashii, T ovatum and T recurvatum are settling in for the winter to come. With luck, seed from T undulatum will germinate next year in situ.
-
Trillium chloropetalum - this is only the second year that this has flowered after being planted 11 years ago!
I guess that it has finally adapted to life in our dry climate garden ;D

My flowering Trillium last May. :)
Trillium grandiflorum was bought couple of years ago from Dryad, as was also red T.chloropetalum, picture in low morning light.
T.grandiflorum 'Flore Pleno' is from Ruksans, and T.chloropetalum var giganteum 'Album' from Estonia.
T.erectum was grown from seeds, and I have other seedlings growing but not yet flowering size.
My own plants are very shy to produce seeds, only T.erectum and the big white T.chloropetalum have had seeds so far.
-
You´ve really got an enchanting garden, Leena! This year surprisingly many of my trilliums produced seed, whereas in other years they scarcely do. Maybe the very warm period starting in April encouraged them to do so.
-
yes, your garden is very beautiful ... trillium seems happy.
Do you ever discover spontaneous trillium seedlings Marriette?
-
This year I discovered quite a lot around one plant, the first time I´m sure they are seedlings. A friend of mine grows trillium for over 30 years and found so many seedlings in his not very big garden, that he gave them away by the dozens. These are some I received from him.
-
Thank you Mariette and Veronique. :)
Mariette, you got some really nice Trilliums, all flowers are different!
I haven't gotten any self sown seedlings though two years ago I sowed some seeds from the big white one near it, nothing has come up so far, but the ones I sowed in a pot came up this spring.
I've also been wondering about my Trillium luteum, why it doesn't produce seeds, and it flowers so late in May, that there haven't been any frost at that time. A while ago I read in Trillium book that it likes to grow in alkaline soil, and mine grows in acid soil, maybe that is the reason. I've been thinking of moving it to a alkaline bed next year.
-
Leena,
My 3 T. luteum never set seeds either. I would love to know why!
-
If hand-pollinated, trilliums reliably set seed with me. Seedlings in the borders are prone to slug-damage in my garden, so may be vanished before noticed.
