Title: Trillium 2021
Post by: Herman Mylemans on March 16, 2021, 08:08:27 AM
Trillium season is starting!
Here always Trillium nivale is the first. Pity that the weather is unstable, low temperature and there has been a lot of rain, even a day with hail.
A lot of other Trilliums have emerged and are waiting for better times!

What a nice display Herman, Trilliums with Hepatica together!
We don't get to see such combination, or at least I don't because the majority of species I have flower long after the Hepatica. Only T. nivale would be so early but I didn't manage to find any to purchase here (or seeds).

Thank you all! This Trillium ovatum form is much earlier then my other ovatum on another place in the garden. I once was forgotten to remove the berries, so you see now a lot of seedlings. On the first picture you see Trillium chloropetalum var. giganteum on the background, this one is earlier then the ovatum.

Gabriella, till now I have never seen good seeds on my Trillium nivale. I don't know why.

This species doesn't come as far north into Canada, who knows why, it is hardy enough. But I know that in its native habitat grows on gravelly, mineral substrate, including g limestone bluffs and crevices.
But it seems to flower well in your garden, it may be a lack of pollinators because it flowers so early.

I will use a brush and see if it helps. The other problem was that if there were seeds they didn’t mature.

Thanks Maggi, I hope it stays that way! In the past gentians grows like weed and suddenly it stops. Till know a lot of Trilliums are growing well. But there is always a danger that a disease appears for a plant family. So I learned that you always need a backup: spreading plants over a great distance or better in different gardens.

This clump of Trillium hibbersonii started as a single seedling about 1970.  It is growing in poor soil and never fertilized as fertilizing killed all the trilliums when a new owner bought Hibberson's garden, so those of us in Victoria learned what not to do.

The flowers open a good pink and gradually fade.

Diane, beautiful hibbersonii. I didn’t now that fertilizing is bad for this Trillium. Maybe that is the reason that I have lost them. So if you have seeds that you can spare, I would-be be very interested.

Diane, that´s a very important information! Usually I have to fertilize all my trilliums to keep them flowering, despite my heavy soil.

Diane,
Interesting about the fertiliser. I don’t feed trilliums in the garden usually, but I do feed the seedlings in pots in the cold frames - I use very dilute tomato fertiliser. I wonder if that is why I lose some seedlings? I have always thought losses were due to the compost deteriorating after a few years - the seedlings can be in the same compost for 4- 5 years, depending on how many years the seeds take to germinate, then the seedlings remain in the same pot for another 2 years or so. When I empty out the pots the soil can be very sticky, and be covered in liverwort.
Do you know if the fertiliser which killed the T. hibbersonii was artificial or organic?
Title: Re: Trillium 2021
Post by: Diane Whitehead on April 10, 2021, 10:20:37 PM
No, I don't know what kind of fertilizer was used.

The man who gave me the seedling had flats of seedlings growing in what I think was a fine gravel - not as small as sand.
Title: Re: Trillium 2021
Post by: Carolyn on April 11, 2021, 09:07:53 AM
Thanks, Diane, it sounds as if the seedlings were growing in something like chick grit - half way between sand and gravel and a very useful product for seedlings.

Mariette, beautiful white Trilliums whatever the name. :)

Diane, also I appreciate the information about fertilizing. It is good to know that it is hardy enough to grow in Canada, so maybe I can plant some of mine outside. Right now they are still in two pots and they are two year old seedlings.

Of course, Diane. :-[ Silly of me, it says so also under your signature:). Only one day of snow, I am so envious.

I think Prague is warmer region than what it is here, or winters are longer here. I will wait a few more years and then plant part of the pot outside and see what happens:).
To very gritty compost if I understood from what you wrote earlier.

In 2003, I planted Trillium hibbersonii in humus rich soil, in shade, it stayed alive till 2012. But it always stayed one plant, there were some seedlings in 2013. But at the moment everything is lost. Maybe is the solution gritty poor soil.
Trillium undulatum is also a very difficult one to keep alive.
Title: Re: Trillium 2021
Post by: ashley on April 12, 2021, 11:05:20 PM
My T. hibbersonii, from seed sown in about 2008, is also in fairly humus-rich soil. 
In all that time individual plants have not bulked up although they slowly multiply by seed.
Title: Re: Trillium 2021
Post by: Diane Whitehead on April 13, 2021, 03:00:42 AM
It grows very slowly from seed. 

Here are seedlings from seed I sowed last June 22.  They germinated September 1 and grew though the winter in my cold greenhouse.  This photo was taken today, and you can see they can be measured in millimetres.

Title: Re: Trillium 2021
Post by: ashley on April 13, 2021, 12:11:56 PM
Even after another year (sown 6/2019) they're still tiny, and all too easy to lose in the garden.
Your pink plant is lovely Diane, and it's very impressive to see how well it has multiplied. 
Clearly my conditions are not ideal yet.   However if ever you have seed to spare I'd love to try some.

Post by: GordonT on April 13, 2021, 01:10:13 PM
Trillium undulatum is also a very difficult one to keep alive.

Herman, Trillium undulatum is a native species here, and to date, I have found it growing under coniferous forests, with deep, humus rich, mossy soil. Companion plants growing in the same area are Cypripedium acaule, Epigaea repens, and Clintonia borealis. The forest floor stays fairly moist and cool in this environment. I now have a densely planted pot of T.undulatum seedlings that I hope to plant in the forested portion of our property.

Oddly I have never been able to successfully germinate seed of Trillium rivale, in spite of several attempts, and have yet to try Trillium hibbersonii. My small collection includes T chloropetalum, T cuneatum, T. erectum, T. grandiflorum, T. luteum, T. ovatum, and T. recurvatum.

GordonT  - My southern land here in Nova Scoitia is covered in T. undulatum.  They are almost impossibles to dig, you dig down sometimes 30cm through moist or dry duff through an entanglement of tree roots and find nothing but a ridiculously long Trillium stem.  The bulb itself is sitting atop wet mud, roots often covering the mud or deep down.  They grow in sun to partial sun due to the wetter climate and the fog belt, not so many in shade.  A stinker to place properly so better to grow by seed and let them do their own thing.

Title: Re: Trillium 2021
Post by: Herman Mylemans on April 13, 2021, 02:43:33 PM
Thank you all for the interesting information.

I think I may conclude:

Trillium hibbersonii in poor gritty sandy soil in shade and no fertilizer. Maybe only some potassium.

Trillium undulatum in very humus acid moist soil in sunny position during flowering time. Never transplanting them.
Compost from coniferous trees.

I will try to find some seeds and see what the future will bring.

I am wondering if there are some soil flora associations that come into play with "difficult" trilliums.  For instance, the types of fungi and and other soil organisms (that includes mycorrhizae) are very different in the duff under pines versus arborvitae versus various deciduous trees, etc.

Trillium pusillum is growing in full sun in a slightly raised bed that has a lot of compost incorporated in it.  It gets a fair amount of moisture from a small boggy area near by, where Epipactus gigantea is trying to take over the world.  Fritillaria camschatcensis and various trollius grow nearby.

True is a long drive John, but maybe it can be combined with other hikes/sightseeings.
Regarding the seeds maturation timing - I am not familiar with this species, but for Trillium grandiflorum and T. erectum I noticed over the years that regardless if we had an early or late spring, the capsules are ready around the same date every year/for a given locality.
So, for large populations where not all plants flower exactly at once, even if you are +/- 1 week out of schedule, you will still find some seeds.

It seems our T. grandiflorum will flower in the same time this year Herman. Too warm in early spring here and probably unusual cold in Belgium.

In the woods a couple of days ago: T. grandiflorum, T. erectum and probably their hybrid (a single specimen).

Yes Ashley, I will post a picture in the Erythronium thread. This is indeed a place where T. grandiflorum propagates by itself with abandon :) reason why I don't feel bad to collect some of its seeds to share.

Herman: here it is a bit in advance, but very welcomed at any time. I don't have other native Trillium species growing in my nearby region.

Kris - I was reading in Fred Case's book on Trilliums that there is one American sp. that will tolerate repeated nightly hard freezes and pop right back.  Name escapes me but was long thought to be extinct.

Post by: Carolyn on May 01, 2021, 10:57:13 PM
Rudi, your trillium looks a bit like T rivale to me, maybe a seedling of the ‘Purple Heart’ form. But this is not possible if it really WAS collected on Vancouver island. Rivale’s range is southern Oregon/Northern California. Hibbersonii is found on Vancouver Island. Could two packets of seeds have been muddled up?
Title: Re: Trillium 2021
Post by: Carolyn on May 01, 2021, 11:08:31 PM
Rudi,
I have just looked in Fred case’s Trillium book. He reckoned that hibbersonii is just a stunted form of ovatum (I think I read somewhere that it is now a species in its own right). Anyway, he says for hibbersonii « petals open clear pink, fading to white », so your lovely pink petals should fade to white.
For rivale he says that in fruit »the berry like capsule falls from the basal attachment without splitting ». I have noticed for hibbersonii in my garden that the berry falls and splits - have to be quick to gather seeds or the ants take them.
The shape of your petals fits rivale better than hibbersonii.
Title: Re: Trillium 2021
Post by: ashley on May 02, 2021, 03:41:01 PM
Also, hibbersonii leaves are sessile.  This looks like a nice Pseudotrillium rivale.
Title: Re: Trillium 2021
Post by: Herman Mylemans on May 02, 2021, 05:28:00 PM
Rudi, it is certainly Pseudotrillium rivale. Like Ashley said hibbersonii leaves are sessile.

The hybrid grows about the same as either species.  In my garden, all three types -- species and hybrids -- make huge clumps if they're not crowded.

Thank you Herman for you kind offer. I have now some seedlings growing from different kinds, so I will think about it (if there is something I don't have and which would grow here).
These T.chloropetalum plants are all from seeds sown 2014 and 2015, and I'm so happy to have them now. :)
In the second picture is a mystery Trillium. They were sown in 2014 as T.parviflorum, and last spring the white ones flowered and I thought they are T.parviflorum. Now the purplish flower had gotten me confused. It grows in the same clump with the white ones and I'm pretty sure they were all sown in the same pot originally. The purple one is flowering now for the first time. The flower shape is different than in any of my T.chloropetalums.
In the last picture the mystery is in the left and bigger T.chloropetalums in the right.

I have suspected that it wasn't the real T.sessile, but it is a very nice plant, short but still relatively big flowers. Do you think it is also a hybrid?

I also have a very similar looking one sold to me as T. sessile.

I first suspected it was not sessile when I saw the "bulb":
[attach=2]

True T. sessile is rhizomatous (see arrow). Collected by a friend on his land in Illinois, USA.  I was a bit baffled when I first examined the structure, as it isn't a straight forward horizontal rhizome as T. cuneatum and T. recurvatum are :

I was thinking at Trillium foetidissimum, that one should be extremely fetid or stinking especially when there is some sun.
Rick, for identification you are right that the rhizomes are important, also the berries. I collect pictures of them on our computer. But I don't have one of Trillium foetidissimum.

I have added a picture from J.F Gyer about the ovary has help.

Here also a lot of leaves are damaged. There was a dry hot week in spring when there were still no leaves on the shrubs. Then there were times with storm and hail, flower stems broke off. Even the development of the berries is bad. Now there is regular water and temperatures around 20°C, but the damage is done. Some of the Trilliums are even already completely at rest.
