Hello fellow trillium devotees.
I was delighted to discover my attempt at pollination of Trillium chloropetalum was successful . It first I thought the ‘berry?’ Wasn’t maturing properly, very dried and hard. I thought I’d let them too long. It was with some delight that I found them ripening and softer. I used info I gained here to clean and sow the seeds. So finger crossed I get some seedlings one day down the track.
Trilliums are rather difficult to acquire here, apart from a few specialty nurseries.
-
I did mean for a few more photos, but I had a hick up.
Seeds were sown last weekend. I enjoyed making a very special site for them and later covered with a old soil sieve, the one pictured is from a previous attempt with seeds I received in a international trillium seed exchange . ( soil sieves are very fashionable as rustic fruit bowls in some parts of hip inner Melbourne 😂)

News of a new species of Trillium described to add to the list of these "bulbs" ( in the widest sense!)
Trillium delicatum A. Floden & E. E. Schill., just published, February 2019 .
Comments from Aaron Floden : "A very rare species, much rarer than the federally endangered T. reliquum which is now known from over 50 populations. This new species is tiny, gregarious in the wild and cultivation forming extensive clumps from thin branching rhizomes. The scale shown is cm. It is also very rare with 4 known sites which could easily be wiped out with some land alteration so delicate in many senses. Its odor is not delicate and is very horse manure like."

A New Species of Trillium (Melanthiaceae) from Central Georgia and its Phylogenetic Position in subgenus Sessilium
Authors: Edward E. Schilling; Aaron Floden; Jayne Lampley; Thomas S. Patrick; Susan B. Farmer
Source: Systematic Botany
Publisher: American Society of Plant Taxonomists
Abstract:
Analysis of molecular phylogenetic data was used to reveal the existence of a novel species of Trillium subgen. Sessilium. Trillium delicatum sp. nov. differs from the two other low-growing species of the subgenus, T. decumbens and T. reliquum, in features such as straight stems and dung-scented flowers. It occurs in wet floodplain forests in the Oconee and Ocmulgee river drainages in central Georgia, and has a distinct floral scent compared to the wide spectrum in Trillium. The molecular phylogenetic results based on four markers (nuclear ribosomal ITS and plastid trnHpsbA, trnL-trnF, and rpl32-trnL spacers) included samples of all species of the subgenus, and documented the distinctiveness of b>T. delicatum as a distinct taxon and also provided resolution of species relationships that suggested that the subgenus originated in southeastern North America with two migrations to western North America. The molecular results also suggested the need for closer examination of T. cuneatum and T. lancifolium, and also to assess whether T. decipiens and T. underwoodii are distinct species. Based on the few known populations and susceptibility to damage by hogs, Trillium delicatum is a rare species requiring protection.

I ordered by correspondence a trillium luteum. I wanted this yellow what seems easy to cultivate ...
but here is what it gives ??? :
is it a species or a hybrid? (which species?)
-
I bought a single bulb of Trillium pusillum in 2005. It has been a great plant, increasing in size every year. Though I've never seen a seed pod on the plant, there are now several seedlings nearby.
-
I received a start of Trillium cuneatum around the same time as the T. pusillum. I've divided the clump several times but don't get seedlings. Behind it is T. chloropetalum. That clump was a single seed pot that I planted out without dividing. I don't remember which seed exchange provided the seeds. It may have been the Alpine Garden Club of British Columbia.

Rimmer thank you! When you google Trillium pusillum var. ozarkianum you will find a lot of different forms, so it is difficult to tell which one is the true form. I see that your Trillium has five major veins per leaf, in a normal pusillum it is 3, I think that is a good sign for yours.
-
Véronique Macrelle, your plant is Trillium recurvatum.
-
thanks for the determination :).
I do not find it as beautiful as Trillium luteum

Véronique, for Trillium recurvatum the sepals must bend down when the flowers are open.

Trillium ovatum also gets a nice colour when the flower is getting older.

This one came to me as Trillium cuneatum, but I think it´s Trillium chloropetalum. I like its brilliant colour and good clumping habit; it´s growing in 4 different places in the garden since I got it 9 years ago.

Mariette, maybe it is Trillium angustipetalum! Does it smell musty? Chloropetalum smells like a rose.

In the Trillium 2017 thread (Replies 135-137) I posted a picture of what I thought might be Trillium rivale leaves, Maggi replied that it wasn't a Trillium and after a bit of excavation it turned out to be a self-sown seedling of Ompholodes cappadocica 'Cherry Ingram' (yes, I know!!)
I persevered, and WOW (at least thrice) there is a Trillium rivale grown from a small bulb I bought in 2016. Aren't I the very happy one ;D

Thank You for pointing to the scent, Herman! There is hardly any to discover, but it´s definitely not pleasant. Very unlike my Trillium albidum, for instance.
The slender habit of the tepals made me consider Trillium angustipetalum, too. Case & Case tell the tepals of this species should be 7 - 14 mm wide, whereas chloropetalum may measure 15 -23 mm. As my plant has tepals 20 mm broad, I thought it to be Trillium chloropetalum. A special feature is that a clump lifted splits into several smaller ones without dividing.
The clump shown yesterday has rather long telpals, measuring 9 cm. Usually they are 7 -8 cm, like with this clump.

Last summer I got fresh seeds of Trillium hibbersonii, and look now! So many seedlings coming up. :) :)
I usually keep Trillium seedlings in the same pot until their second year when I move them to a bigger pot as a clump, but should I divide these already this summer to several pots?

Leena, nice to see so many seedlings of hibbersoni.
I would leave the seedlings together and put them as a clump in a larger pot (after summer). After you have seen 3 leaves you can divide them in different pots, I wait to plant them out in the garden till they have flowered.

This one I´ve got as Trillium albidum. The anthersacs should open latrorse, but to me it looks introrse. Probably a matter for more knowledgeble people.

This bunch of seedlings is grown from US - seed, the donor wrote: sessile - type, 25 cm, maroon. The flowers start a more brilliant red, but later fade to a more brownish tone. Any ideas what species this might be?

I think it might be a form of fasciation. It will be interesting to see if it recurs next year.

Here trilliums are ahead of all previous years, T.chloropetalum is in bud, and today I noticed that T.luteum has come up. Normally it flowers here in the end of May!
-
Rick, those are so beautiful images!
:) And the funny thing is, is that camera was not a ground level! The pics were take with the camera held well above my head, because Snow trilliums were on a cliff.
I had arrived at the Scientific and Natural Area, just as the sun went below the horizon - just so so pics then. I had planned to come earlier, but had so much fun spending the day with the wild Pulsatilla patens, that I lost track of time. But, I was able to go back the next day for better light and better pics.
(Pulsatilla pics wil be coming on the Pulsatilla thread.)

Herman, you have such good looking big clumps of Trilliums!
Do you feed them or what is your soil like?

Leena, the soil contains some clay and a lot of humus. In March and September I give them garden potash from DCM and in May some organic fertilizer for garden flowers.

Trillium undulatum -pot grown as it needs very acidic, free-draining sandy soil. Despite being a small Trillium species it produces deep searching roots. Not hard to grow if given the above conditions. Watering is with rainwater to which 10mls Cider vinegar per litre is added about every 3rd watering. Prone to snail attacks (the new shoot of this plant was nibbled as it “broke cover” -hence the slight deformity to the leaftips.

Steve, Your Trillium undulatum is doing very well! Congratulations!
-
Thanks Herman.
It produced seed last year when I self-pollinated it. I sowed the seed immediately but I don’t suppose I will see any seedlings for another year, if at all.
-
Wonderful undulatum, Steve, and congratulations on growing it so well! I doubt this is even above ground yet, here in Nova Scotia.

Trillium season has finally begun for me. Last year, I received two new plants from a friend in Victoria BC , and they have both settled into the garden. Of the two, I am particularly happy with what was sent to me as Trillium kurabayashii (I still have to examine the floral parts to confirm identification). The other newcomer was Trillium ovatum. It will take another year to adjust to the garden here (first flowering was very small).
[attachimg=1]
The other Trilliums are taking their time this year. This past winter has mixed up the bloom sequence in the garden. Up until this year, Trillium cuneatum has been in bloom, before Sanguinaria canadensis multiplex, but it looks as if the Bloodroot will be done, before the trillium buds open.

Gordon, I doubt that it is kurabayashii. The petals should be oblanceolate and widest about the middle.
-
I have protected some of my biggest Trilliums with fleece in the frosty nights, and they keep on flowering well.
The first is T.chloropetalum giganteum 'Album' ,and in the second picture there is a clump of my seed grown T.chloropetalum (seeds from Dryad 2013), flowering for the first time. I'm wondering if I dare divide them now when they flower?
-
Trillium kurabayashii (if it is true, I don't know) has been flowering for a month now.
Very small T.sessile opened a week ago and T.luteum just last week.
-
Leena, beautiful Trilliums in a natural environment.
-
Thank you Herman. I really like Trilliums, and mostly they grow well, but for some reason I lost my T.grandiflorum last winter. :(
It wasn't even a very bad winter so I don't know why it never came up in the spring. I'm glad I have seedlings of T.grandiflorum growing now.

Leena, are you sure they are death? Can you check of there are still rhizomes in the ground that are intact? Previous summer was here very hot and dry so, a lot of Trilliums were very early in rest. The waterlevel is not normalized yet. I think that is why the flowering and coming up here was less then previous year.
-
It was also here very dry last summer, and hot, and the bed where my T.grandiflorum was, was drier than the ones where T.chloropetalums are. I hope you are right, and I will dig carefully to see if the rhizome is intact. Can Trilliums be below ground for one summer and then still come up the next summer?

Leena,when the rhizome is not rotten away they can come up again.
-
I use to grow some martagon section lilies in full sun (L. tsingtauense x (L. distichum or L. medeoloides)). Without any soil disturbance, some years they would simply decide not to grow above ground, and the following year would come up, happy as can be.
I had a botany professor and an English mycologist visit my garden just a few days ago, and I mentioned this to them. Mike said, "Oh yes, Trilliums can do this, too." Although he did not specify any particular species.
-
We also went on a "smelling spree". My nose is different in that I don't always smell what most people do, and then I do smell some things most people don't, so it's especially good to to get my guests' opinions.
So it's good to know that my Trillium luteum does have a faint lemon smell (unbeknownst to me), but we all smelled the very strong and pleasant fruitiness of this sessile group hybrid:
[attachimg=1]
Last year a friend sent me some Trillium recuvatum that he had been cultivating in his garden, from wild stock on his property. When it first came up this spring, I wondered if they really were recurvatum, as the distinguishing features weren't that evident before flowering. But the leaf color was incredibly dark and saturated.
[attachimg=2]
[attachimg=3]
But when it bloomed, there was no mistake:
[attachimg=4]
[attachimg=5]
I couldn't smell anything, but Mike said it had a slight spicy scent.
-
Rick, nice Trilliums! Your recurvatum has very beautiful dark leaves.
-
Rick, how suberb leaves!
I dug carefully where my T.grandiflorum should have been, and there was no rhizome, just slightly loose soil, so it has died. :(
Just two meters from it is one T.chloropetalum which is fine, as is T.nivale, so it is a mystery why this one disappeared.
-
Mycorrhizal association? I have never seen T. grandiflorum where T. nivale grow, although T. cernuum grow with both of them. We don't have any native triliums in Minnesota that I have seen that are related to chloropetalum. Grandiflorum seems to like acid soils, so I don't think there is any problem there.
-
Plants native to the west coast of North America are accustomed to rainless summers (unless they grow in Alaska, which seems to get daily rain). That is probably why your chloropetalum survived while the eastern grandiflorum, which expects rain in the summer, did not.

Diane, thank you for this information. :) I will have to make sure I plant my T.grandiflorum seedlings to a place which keeps moist more, and doesn't dry out!

I beg to differ about T. grandiflorum - in SW Ontario most summers are hot and extremely dry, especially in the last years. Large populations grow very well in shaded deciduous forests. Of course it rains once in a while. but they withstand quite some drought at times (the soil type is very important probably).

And a picture with T. cuneatum, the sweet Betsy. I think I posted the luteum in the general thread.

That is a very beautiful plant! Is that Primula sieboldii in the background? Here it doesn't flower yet.
By the way, I smelled my T.luteum yesterday and it does have lemony smell, not strong but very nice. :)
-
I have this Primula or a similar variety under the name Primula sieboldii "Tah-Ni". still in pot, and I do not know where I should install it in the garden. yours seems to be pleased with its Trillium.
I despair with my seedlings of Trillium: nothing but a small Trillium grandiflorum of 3 cm on 0.3 cm on at least 10 attempts over 3 years I would try again the one you find "easy" but if nothing else. .. ???

Yes Leena, P. sieboldii 'Late Snow' (with the so many cultivars sieboldii has who knows...). Probably a bit early because of the rains, otherwise still cool for this time of year, especially at night (below 10C).

With P. sieboldii truth is that is quite impossible to distinguish some of the cultivars. All beautiful though. Yes, part-shade and slightly moist (or more) fits them well.
I am sorry for your Trillium adventures but I really have nothing more to add or show than I already did. All germinates from fresh or moist kept seeds (warm/cold).

Three years is a short time when growing Trilliums. At least for me it takes two years for the seedlings to come up (even from fresh seeds), and the first year they are only one small leaf. For me the fastest to flower has been five years since germination. And not all seeds, especially dry ones, germinate in two years. This year I have noticed seedlings in bed where I have put the empty seedpots in 2015, so don't throw away anything, they still might germinate one day. :)

Mariette, it is a great plant, I love the leaves and contrast in them and the flower.

Thank You, all! It´s raised from seed received as Trillium kurabayashii, but I´ll have to check if that´s correct when the flowers are fully developed. Having lost my first one to rodents, I now keep more interesting selections potted till I may divide them. They stay in the greenhouse during periods of frost, so this one is slightly ahead of those in the borders.

Hi Steve,
Sorry to resurrect such an old topic, but I’m looking for info on T. nivale composts. You look to be doing pretty well with it, so can I ask what you grow them in? I’ve heard just loam/grit/sand without added organics but not sure.
Cheers,
Alex
-
Hi Alex,
It likes a well-drained compost that is not overly acidic. I use loam, granite grit, perlite and leaf mould (composted bark also works). My mixes are pretty lean with over 60% drainage material (grit and perlite). I give high nitrogen liquid feeds from as soon as it appears until leaf growth is complete.
Cheers,
Steve
-
Excellent, thanks very much for that! I was leaning towards that sort of idea but very good to have it confirmed by someone who’s had a bit of success!
