Trillium 2018

[Gabriela]

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.

[Gabriela]

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?

[Ian Y]

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.

[Michael J Barrett]

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.

[Rick R.]

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.

[Leena]

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.

[Maggi Young]

By jove- you've done well there, Michael!

[GordonT]

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
cheers
