Trillium 2017

[Leena]

Mariette, when My T.chlorpetalum giganteum 'Album' flowers in May, I will look and compare it with your plant. In last years pictures I can't see the ovary well.

Last summer I received two small bulbs of Trillium nivale, and I planted them in the ground. I have been looking for them all April, and now finally the ground has melted in that bed, and today I saw them come up and the other one has a bud! I never expected them to flower so soon, so young. And I am so happy that they had survived a difficult winter. It is small and so pretty!

This clump of Trillium stramineum is blooming in the woodland garden.  It came from Richard Vagner's old garden in Gatlinburg, Tennessee, but I don't recall who gave it to Richard before that.

Thank You, Leena! Itīs good to see that Tr. nivale is doing well in Your garden!
 Most of my first acquisitions of trillium were distroyed by slugs, thats why I raise as many as possible from seed to select more robust strains. It worked quite well for me, but unfortunately many trilliums raised from seed harvested in gardens are either hybrids or turn out to be wrongly named. Nevertheless, there are some attractive plants among them. I rely on the book of Case & Case to determine the species, but unfortunately it doesnīt always mention the colour of the ovary of white forms.

Spent a long time today untangling the roots of a very congested pot of Trillium rivale seedlings.  The pot was sown in late November 2011 and germinated in March 2013.  A few flowered last year there was mass flowering this year.  I counted at least 75 rhizomes.

Wim, I love the leaves of T.discolor, perfect with the flower.
What a clump of seedlings, Roma, congratulations.

Like Mariette, I try to raise more plants from seeds so that I would get some which are suitable to my climate. Winter 2015-16 was very cold with a little snow cover, and I lost many young seedlings, also T.rivale (but now I have new plants germinated from seed ex seeds  . Since then I try to keep the seedlings in pots until they are older (three years old T.chloropetalum seedlings survived in the ground), but the trouble is that I have only root cellar to keep the seedlings, and they start to grow too early there, in March, when I can't take the outside yet, and inside the house it is too warm for them.
Case's book is good, I got it as a Christmas present last year.

Some trillium in the garden
Trillium sessile -NW Ohio
trillium sessile - Indiana from Boots Case' childhood home
T viridescens- ex Case
t viride- SE MO with T recurvatum in back
T recurvatum shayei

[Rimmer de Vries]

Trillium maculatum
T cuneatum
Some yellow trillium forms- maculatum luteum and discolour
Trillium recumbens
Last one -i dont recall name- not T decipens?

[Herman Mylemans]

Rimmer, I believe that decipiens should have a longer stem.
Here is Trillium stamineum.

Trillium undulatum

[Carolyn]

Now you are making us all jealous, Steve!
Beautiful flower.

Oh my!

[Rick R.]

T. decipiens would have a horizontal rhizome.

That one looks a lot like a sessile type I have (that is not T. sessile), but it does not have horizontal rhizomes.  This one doesn't key out nicely to any species; I believe it must be a hybrid.

Trillium undulatum

Steve, a very beautiful Trillium undulatum. This one is very difficult in Belgium.

Herman, I have a warm, fairly sheltered, sloped south-facing garden. My garden is too hot for undulatum so I grow it in a pot kept in a shade frame. The compost is a free-draining mix of silica sand, granite grit and Scots Pine needles/leaf mould to which I add some finely chopped sphagnum moss. This mix is VERY acidic. I only water with rainwater/RO (reverse osmosis treated tap-water) water and add 10ml cider vinegar to 1L every 2nd/3rd watering.

The plant is seed-raised from Canadian seed bought on eBay some years back. Germination was poor and the seedlings dwindled over the following years as I didn't know what conditions they liked. Eventually I was left with one sickly young plant. I gleaned some info from the internet on how to grow undulatum and so altered the compost and watered as above; the plant has since gone from strength to strength. Though still a small plant it has two growths this year.

I am no expert but I think that the important issues are a free-draining mix and maintaining a very acidic compost (pH <4.5). A very acid compost limits decomposition of the organic content in the mix which helps preserve the compost structure/free drainage and suppresses pathogenic fungi.

Of course it is possible that all of the above is nonsense and I have simply enjoyed beginner's luck.
