Hello Marianne, welcome to the forum; some lovely Trillium there. I wasn't familiar with the one named "Gothenburg pink strain", but when I googled it, see that it's a pink form of T. grandiflorum, a treasure.

Hi Mark, thanks for the welcome, and thanks again Roland, sweet of you.Yes, it's a T. grandiflorum, I forgot to write that when I posted the pictures and yes it's a real treasure.I will come back tomorrow and tell you more about it, you see, it's bedtime here in Sweden.
Good night everyoneMarianne
You have some nice Trilliums ;)
Where do you get them from, do you have a source in Sweden?
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
This is the story of the beautiful T. grandiflorum "Gothenburg pink strain". I have translated what the man himself (Henrik Zetterlund) who "made" this beaty with his co workers have written about it on his blog. http://henrikzetterlund.wordpress.com/Henrik works at the Botanical Garden of Gothenburg, a beautiful garden to visit.
In the 1950:is the garden received a pink form from Edinburgh, which only could be multiply by divisions, since the seeds gave both pink and white forms. 1995 the garden received 2 pink forms from Fred and Boots Case from Saginaw, Michigan.The garden started to hand-pollinate the pink forms and in the year 2000 all the seedlings came out true pink and still does.The forms that was from Fred and Boots was found at the Blue Ridge Mountains in Virginia.
My plant was given to me by a friend as a gift, I'm a very lucky person who have such a wonderful friend.
I have bought mostly of my Trilliums from plantmarkets here in Sweden, and some from the Botanical garden of Gothenburg. Not very many nurserys have Trilliums, and if they do, it's mostly T. albidum and T. luteum.Trilliums like T. chloropetalum and T. kurabayashii is hard to find here in Sweden, and it's even harder to find these 2 with colors like pink, white and yellow flowers.
Is it hard to find Trilliums in Norway?
It is very unusual to find trilliums for sale in nurseries here. However some small ones sell on internet. I don't have many plants and most are bought from abroad. The last year I've started sowing to get more than one plant of each species to plant out in my woodland.
'No room at mill '' .....A recent view of the shade house where I sow some of my Trillium seed.About 230 pots ,an estimation of over 9000 various seeds/seedlings .Of course not all will reach flowering .
I refuse to show a picture of about 180 large pots of near/mature plants raised from seed that need to be planted out.....
Bottom of the South Island New Zealand
Zone 8 maritime climate
1100mm,(40 in),rainfall p.a.
Nil snow cover
Except for the 50 odd pots I've just sown, most pots have germination currently appearing under ground as shown in this pic of seed sown March 2014 from T.chloro/albidum white that are throwing doubles .Only another another 5 years to see if they come true .....
Could anyone offer advice on how best to handle seed of the following species (dry seed from the exchanges this year): Trillium albidum, Trillium chloropetalum, and Pseudotrillium rivale.
My usual routine would be to soak the seed before planting it. What to do with the seed flats is the main question. Should the pots be kept at room temp for a while before cold stratification? How much cold should the seed pots experience? There is still plenty of snow on the ground here,although daytime high temperatures are trending upward (0 C to 10 C by day, and -8 c to -1 c overnight). I could place the pots outside, or in our cool basement for steady cool temperatures, or in an unheated polytunnel greenhouse (might get too warm during the day).
Any advice would be welcome.
