Trillium 2020

[Maggi Young]

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.

[Rick R.]

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.   The non-flowering plants are already turning yellow.  Just as Ian says, flowering (and seeding) bulb plants stay green longer.


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'.

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.

T. sessile - notice the connectives extended above the anthers (2-5 mm)

T. cuneatum

Still question mark the mottled foliage is hardly any indication for the species.

Trillium grandiflorum is at flowering peak in Ontario, I didn't went especially to watch it in the woods yet, so just a few pictures for now.
I'll start with my first to flower from seeds (5 years), small flower but great potential


And from the woods yesterday, not much time, busy with the Hepatica actually but couldn't abstain...

[Leena]

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.

Beautiful Trilliums Gabriela!

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
It is the same with Gentiana acaulis, you have that name as a group of plants and also as species

[Herman Mylemans]

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.

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.

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.

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.

[kris]

Hi Gabriela -I forgot to add that I have 3 little seedlings of Trillium grandiflorum  from your seed  I got 3 years ago!!

[Leena]

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.

[Rick R.]

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?
