Trillium kurabayashii from seed sown 9/15/2009.

First Trillium  out here is this  little  T. ovatum forma maculosum - the photo is from Ian's Bulb Log 0917

I saw that in Ian's blog - just stunning!

It is one I've coveted for a very long time.  Very glad to see you're getting seed and you now have babies.

Maggi, T. ovatum forma maculosum is very beautiful. I have sown them in 2015, so it is still a long time to wait.
Trillium nivale is enjoying the nice weather.

Herman - your T. nivale is beautiful - it is my favourite !

My slug eaten lowly single blooming size T. nivale is waiting for some sun (which has been quite lacking here) to open.

Herman - your T. nivale grouping is fabulous. How long have you had them?

Julie, it is about 8 years ago that I planted  Trillium nivale on that place.

Trillium rivale, first flower this year.

The area you have them planted looks quite sunny and mulched with bark. I would like for mine to spread well like yours, any recommendations?

Julie, they are growing outside in humus rich soil in semi-shade, not too wet. This one stand under branches from a tree (from our neighbour, leaves appear very late), so it is a very cool position in summer and now the Trillium gets a lot of light.

Another plant is standing in a more shading and more acid position and flowers always much later (about a month), the place is also more wet. This plant doesn’t grow as good as the other one, so I now have done  a bit tufa among the soil to see if it will grow better. 

Once they are settled they dislike removing.

Thank you Herman.

Where mine is growing it is only sunny in the morning, by noon it is in the shade of our house. We have been having so much rain everywhere is wet.

I have at least one more seedling and I will try to find a location under a late leafing deciduous tree, making sure the soil is humus rich.

Trillium kurabayashii

Trillium kurabayashii

David, that is early for kurabayashii. Are you sure it is kurabayashii? Here in Belgium just the nose is appearing. On the other hand Trillium chloropetalum var. gigenteum is starting to flower. Anyway it is a beautiful Trillium. I have added the berry of kurabayashii.

What's been sold as 'kurabayashii' very often turns out to be 'chloropetalum var. giganteum'. I bought my 'kurabayashii ' plants from a well known nursery in the UK and they turned to be 'chloropetalum var. giganteum' .  Someone posted a comment on this forum how you can see whether you have  kurabayashii or chloropetalum var. giganteum.

i guess i found a sure and quite easy method to differentiate between Trillium chloropetalum <-> Trillium kurabayashii. i checked the Trillium key in "the flora of north america" to find remarkable characteristics. according to the key with focus on differences in filaments and ovary, i made a fotocollage to show the differences which should be checked easily by everyone. the legend is in german, but should be understand. the chloropetalum foto was taken of a plant in my garden (wrongly thought to be a kurabayashii), the kurabayashii foto was found in internet. i tried to find a foto of a plant described as taken in the wild in an area where kurabayashii is native (as i remember it was taken in oregon). the kurabayashii foto fits all filament + ovary characteristics from the Trillium key. the main difference is the length of the filament...in chloropetalum the ratio between length of filaments is about the double of the length of the ovary, in kurabayshii the ratio is about equal. the length of the connective (the short appendix after the pollensacs; in kurabayashii absent or very short, in chloropetalum about 1,5 mm) could be a second characteristic as an addition to the main difference of the filament-ovary-ratio.

Today I have taken some pictures from Trillium chloropetalum var. giganteum
