Trillium 2020

[Tristan_He]

Trillium all germinate right now? ?
is T grandiflora later? my only seedling from last year has not yet reappeared ..
I have about twenty seedling pots of all ages (0-5 years) which still do not show seedlings ...

Hi Véronique, they should be germinating / shooting around now.... hopefully! Still a decent chance it will come up. Maybe a good idea to put out some slug pellets just in case.

Trillium ovatum

Trillium chloropetalum var. giganteum (flowers 10 cm)

Trillium pusillum var. pusillum is going to start.

Trillium hibbersonii, looking a little bit crowded. I must split this clump later this year!
T.  ovatum (or maybe grandiflorum? I puzzle over this every year)
T. rivale. I have sown lots of these and they are now scattered throughout the garden, much to the delight of Mr Pheasant who  pecks off the flower buds - pic 4.

Trillium kurabayashii

Trillium cuneatum

Trillium pusillum var. pusillum

Herman,
Lovely big clumps of cuneatum and pusillum.  Do you find that your pusillum increases vegetatively? I have had a couple of plants for about 8 - 10 years and they have not increased. I am patiently trying to build up a nice group from seed.

Carolyn, yes they increase vegetatively. This Trillium stands there for about 9 years in a humus rich soil.

Trillium hibbersonii has finally received official recognition.

https://www.mapress.com/j/pt/article/download/phytotaxa.436.2.9/39076
Trillium hibbersonii was officially described as a new species.

Interesting is the finding that T. hibbersonii ribosomal DNA is closer to T. erectum
than to T. ovatum.

Thank you Diane for posting this interesting information!

Beautiful Trillium David! Does it set seeds?

Hello Herman, this is a plant I bought late in 2016 and it flowered for the first time in 2019, but you may remember that the flower was fasciated. Much better now though. I'll keep an eye on it and see if it produces any seed.

Thanks David. Let us hope that it produces some seeds.

It looks much lovelier this year than last.

Could this also mean than T.hibbersonii is as hardy as T.erectum?
I have full pot of T.hibbersonii seedlings which germinated last spring  . I'm wondering if I could  plant them outside this year or still keep in pot just in case the next winter will be a cold one..

Leena, I don't think they are as hardy as erectum. Trillium erectum grows very well in our garden but hibbersonii doesn't. I would keep them in pot till they are flowering size and then put a part in the garden. If the pot is a small one then put the whole clump in a bigger pot.
A few years ago I had a flower in the garden and later some seedlings but they vanished!
