Trillium nivale is starting again.

Trillium chloropetalum var. giganteum is also very early.

Also in my garden, usually the large-flowered trilliums do not coincide with snowdrops.

Wow! already?!
T. nivale is very early by nature but I didn't know T. chloropetalum and ovatum can also flower so early in the spring.

Chloropetalum and kurabayashii have begun flowering here too, and rivale is next.  I don't keep records but think this may be slightly earlier than usual.

Thank you Maggi, interesting article.

It is, isn't it.  Beautiful photographs too.

I was interested to read that '... old clumps may have two or three stems each season', rather than the bigger clumps sometimes shown here and elsewhere. 
Do plants usually bulk up more under garden conditions or rather are these big clumps normally groups of separate individuals?
Title: Re: Trillium 2022
Post by: Mariette on March 31, 2022, 08:01:47 PM
In my garden, this depends on the clone. Some bulk very quickly whereas a nice green-flowered Trillium chloropetalum I grow doesn´t develop more than three flowers since many years, for instance. Most of the hybrids clump well, the parents of this one were given as Trillium sessile ´Rubrum´ and albidum, the former being a somewhat doubtful name.

That's encouraging Mariette; thank you.  Some of my plants are up to 3 stems now so perhaps they're (slooooowly ;)) on their way to decent clumps .

A very well written and enjoyable article Maggi. Also, how nice to see the flower variations among the wild populations. It resonates a bit with what's happening here with other Trillium species.

It is a very handsome plant Mariette, regardless of the parentage. Does it have any fragrance? Usually T. albidum has a nice rose fragrance, which may be inherited by hybrids.

Herman, very nice clumps of Trilliums! It is good to know the year of sowing. Also here it has taken around 7 years from sowing until flowering.

Most of the hybrids clump well, the parents of this one were given as Trillium sessile ´Rubrum´ and albidum, the former being a somewhat doubtful name.

Mariette, I like this plant very much. It has quite wide petals with nice colour. :)
Also your picture of T.kurabayashii is so nice scene.
Title: Re: Trillium 2022
Post by: Mariette on April 04, 2022, 11:02:43 AM
Thank You, Leena! I just read that it takes well nurtured trilliums to develop the best colouring of the flowers. In former years I was slightly disappointed by the washed-off colouring of this hybrid´s flowers, which were no match for the strong pattern of the leaves. Nowadays I try to feed my trilliums every year, and now the colour of this hybrid has improved.

@ Gabriela: I cannot smell any fragrance with this hybrid right now, but maybe this is because of the temperatures being rather low. We had some frost during the nights, down to - 3°C, but fortunately all trilliums escaped unscathed.
In Germany, trilliums are frequently sold under wrong names, and few people try to verify the species. This hybrid and several others were raised from seed of two trilliums friends bought as Trillium albidum and sessile rubrum. The latter is a name errouneously applied to kurabayashii, which is hardly available over here - in most cases Trillium chloropetalum is sold as "kurabayashii". Judging from the white and reddish flowering hybrids I achieved from this seed, there must be a good deal of Trillium chloropetalum in their genes.

Mariette, that is good to know! I have most of my Trilliums growing near Meconopsis and I have given Meconopsis plenty of manure compost, so I think Trilliums have gotten some of it too. I will have to keep in mind this when I plant new seedlings from pots to outside bed.

Interesting how form yellow parents the seedlings came red, I would have expected some variation in color.

Mariette: honestly I wouldn't mind to have available to buy such Trillium, even if mislabeled :)
One specialized little nursery who used to have few Trilliums closed down; another one which has some Trillium is in BC (in a region called the 'tropical' region of Canada). Various few plants I purchased over the years (not Trilliums) never adapt here. So, growing from seeds remains an only option for us.

Claire, beautiful Trillium clumps! They are growing very well in your garden. Next week the weather here will change again and it will be drier and warmer. Now there was frost, snow, rain, wind, more autumn than spring. Trillium ovatum f. maculosum Is very beautiful, that one is still missing in my collection.

Thank you, Herman, for the kind remarks.  Trillium ovatum f. maculosum was grown from seeds collected by Arlen Hill, who shared them with me.  I was a bit dubious about what the difference would be with Trillium ovatum.  I'm now a believer!

Post by: Mariette on April 09, 2022, 05:15:32 PM
Claire, the combination of white flowers with these very special-marked leaves of Your Trillium ovatum f. maculosum is especially beautiful!

Gabriela, trilliums are rather easily available here, but my first purchases about 25 years ago were frequently lost to slugs. When I noticed that the two trilliums of my friends had leaves of thicker substance I asked for seed in the hope of a better resistance to slugs - which obviously worked. This one of the whites I raised from that bulk of seeds.

(https://up.picr.de/43365466tg.jpg)

This is another one of the reddish flowering seedlings.

(https://up.picr.de/43365473kj.jpg)

Since then, I tried to raise as many trilliums as possible from seed - if they survive the seedling-stage unharmed by slugs, they will show no problems as mature plants, I thought. This is a creamy yellow Trillium chloropetalum.

Mariette, again beautiful pictures, and I didn't know there could be differences in the thickness of leaves, it is good to know some can be more resistant to slugs which we have too.

Herman, you clumps are so big! I especially liked T.cuneatum leaves.

Claire, you have so beautiful Trilliums and T.pusillum looks wonderful. Cream coloured T.albidum is also very nice. :)
Title: Re: Trillium 2022
Post by: Gabriela on April 10, 2022, 03:13:22 PM
Mariette, you have now some very happy looking Trilliums :)
Slugs are not a big problem here, they do more damage in my rockery, or that's where I see the damage. The problem is that my shade space is coming to an end, so soon I will have to abstain from growing more such species.

Growing from seeds is always the better way to obtain seedlings adapted to ones garden, from any point of view.

Trilliums are flowering here now, this year later than usually.
Trillium chloropetalums.
The second plant is a very tight clump, started only with one rhizome 7 years ago. I wonder if I should divide it, but maybe it is difficult because all stems seem to grow very close to each other.
The third picture is of a group of seedlings sown 2016 (seeds from a kind forumist from NZ) and one of the seedlings has yellow flower. :)

These Trilliums were  sown 2014, Trillium erectum klon5,
and they are very nice outward facing, and nice lighter red colour.
Then there is this small clump. It is either T.rugelii or more likely T.vaseyi album x T.sulcatum. Both were sown from seed ex seeds 2014-15, and the other one has died.
Flower is smallish and down facing so I had to raise it with fingers for the picture.

Beautiful Trilliums Leena!
Here many Trilliums have waived the drought in May. That's why I don't take many pictures anymore. Now some more water has fallen again, but most flowers will not recover. There are also a lot of snails this year. Last year it was better for the Trilliums.

It is different each year. Here this was a bad year for snowdrops and hellebores, but a good one for Corydalis and also Trilliums, it seems.

Marc, Trilliums are beautiful plants for shade. They do need sufficient moisture during the growing and flowering season.
They are actually far too little used in gardens.

Nice Leena!
By the time they started here it got very dry so the Trilliums were not so happy this year. Yours are very good looking.
I also had a first flower in T. grandiflorum after 4 years, the clump will improve with age :)
The pink is beautiful, I cannot give an opinion on the species.

In nature, T. cuneatum naturally dies back quite early.  But given enough moisture, it will stay green and lovely for most of the season.

Rick, here it is the same. Last year there was enough rain and the leaves stayed fresh longer than this year. This year, the rain was too late, the damage is done.
That is sometimes the unfortunate thing about growing plants, you look forward for a year to see the flower and then dry weather causes disappointment.
