Trillium 2012

[Shadylanejewel]

Well well I haven't checked this post since yesterday and here are several photos of Trillium nivale.  Something must not be working right with the "Show unread posts since last visit." link, as every time I'd check, only a very few posts would show up and this one wasn't on the list.

I started another post under Plant Identification Questions and Answers for id help of some Trillium nivale I bought this year.  http://www.srgc.org.uk/forum/index.php?topic=8769.0  The more I look at these and other photos of T. nivale, the more I'm sure I bought T. pusillum.

After seeing the picture of John Aipassa's Trillium kurabayashii I took a torch light and went out into the garden to check my Trillium kurabayashii's. I think that my plants might also have this smut disease. I took some pictures this morning. What is the verdict?

The markings along the stems could be the fungus, however, I'm not positive.  If you are willing to sacrifice a stem, cut one which has the lesions, put it in a baggie and bring it inside where it is warm.  I'm going by memory here so not sure if this is exactly right.  If it is smut, it will take a week or so for the lesions to mature and rupture.  Hopefully, if it is smut, the plants in your garden will not have advanced to this point (although it would depend on the weather).  Then you would have time to remove the plants and if it is not, then you'll only be out one stem instead of all your plants.

Your T. cuneatum is huge and has gorgeous leaf mottling!  

Wolfgang & Karl - I can't wait to have a nice grouping of T. nivale like both of you.  

Karl - what in the world did you do to get that many seedlings of T. angustipetalum?  

Jim - I hope all is well for your T. nivale.

Mike - T. ovatum 'Roy Elliott' sure is a cute little trillium.

Hopefully within the next few days, this little T. rivale will open.  (sorry the photo is a little blurry)

Trillium ovatum are now in bloom - just checked a few days ago and didn't see any now they are starting to show all over.  We have hundreds throughout our 8 acres - the fragrance is just wonderful on a warm day.  Unfortunately, we haven't had one of those since last year.

Well some happy news for me. My first and healthy kurabayashii flowering now . At least I can enjoy this one. I checked all my other kurabs, albidums etc. growing on other places in the garden. None of them have the spots or lesions, phew! Three other kurabayashii growing close to the infected one also have no spots or lesions, hmm .

I have no idea where my fungus came from. Almost all my western sessiles are of UK (Scottish) origin. A few from Lithuania and some angustipetalum seedlings from the PNW in the US.

I have enclosed a photo of an infected Trillium with mature sori including spores on the stem. The photo is from the Oregon State University http://oregonstate.edu/dept/nurspest/smut_Trillium.html

Also a photo of one of my cuneatum. I like this dark one with beautiful mottling on the leaves.

Well some happy news for me.

John - that is very good news!  Great to hear the fungus isn't widespread in your garden.

I have no idea where my fungus came from.

After reading most everything I could find on the net, as you've found it would be difficult to determine the original source.

Also a photo of one of my cuneatum. I like this dark one with beautiful mottling on the leaves.

  - Love the bright spring green in contrast to the deep dark chocolate color.  The mottling is exceptional!

Julie I do not know what I do, maybe I'm just lucky 
or it is what I do in my soil, peat (acid sphagnum) lot of old beech leaves and fir needles mixed with my ordinary good mould.

 One of my first apetalon flourish

maybe I'm just lucky 

I'd say you have the luck of the Irish except that I assume based on your location that you are Danish?

Nature adds maple leaves and I add other ingredients (such as fir needles) to my rocky soil, but it seems to increase the worms which increases the moles, which increases the voles, which decrease the trilliums.   

Your T. apetalon is Beautiful!

Although Trilliums are woodland plants they like to have sufficient light.

Here is a photo of kurabayashii growing in deep shade. And another one which is growing with much more light available. The plants are seedlings from the same batch. The one in deep shade does not develop the beautiful markings on the leaves and stays a little dull. It does not clump well either since it has only one stem for a couple of years now since it started to flower.

With me one of very few growing very well outdors and splitting very well, too. May be my are of different origin?

Kurabayashii is easy and clumps up very well in the garden normally. Last late summer I dug up my oldest rhizome. It had more than 15 large offsets. I took them off and replanted them elsewhere in the garden. All of them have come up and some are now growing further with even two stems already. Can't have enough of kurabayashii, my favourite Trillium.
So my clumps with sufficient light do very well. Only the same seedlings I planted in deep shade will not clump up as well as their brothers and sisters. I am going to replant these ones (6 mature rhizomes) to a more sunnier spot in the garden in late August this year.

Of different origin is possible, but true kurabayashii is only known from two small areas: the redwoods in the California/Oregon border area (Klamath & Siskiyou Mountains) and a small area in the Sierra Nevada mountains in California. I believe kurabs of garden origin are likely close related and possibly not pure anymore and have hybridized with red chloropetalum in all these years of cultivation. It is not long ago that the chloropetalum sold and growing in the garden are actually considered to be kurabayashii.

My so called chloropetalum does not do very well as my kurabayashii though. Some have disappeared, some stay dormant for one or two years and some will not clump up well. And they flower later than my kurabs.

Trillium flexipes

[Paul T]

Perfect flower, Michael.  Beautiful!

[Shadylanejewel]

Perfect flower, Michael.  Beautiful!

I agree - exquisite.  T. flexipes is one of my favorites. 

Mine reach over 2 feet tall (as long as nothing eats them).  Last year my cage wasn't tall enough so this year I have a 4' cage over them.

Beautiful flexipes Michael. Still to early to any of my flexipes flourish.

One of mine ovatum open the flowers yesterday and for me it is one of the best; ovatum 'Roy Elliot' only about 15 cm. high. and grow very well.

My first chloropetalum, maybe v. giganteum. I got it several years ago as Californicum Rubrum and I mean it is a old name for chloropetalum v. giganteum, if there are diffrent between chloropetalum and the variety giganteum?

My first smalii flourish and it is plants with any petals (smallii can get from 0 to 3 petals and mostly they are deform.

Trillium x miyabeanum with 3 petals and it is sterile.

Trillium Pusillum looking wonderful today.

[Shadylanejewel]

I love this time of year!

Trillium rivale seedling first year bloom.

Just a few of the many Trillium ovatum in our woods and one T. ovatum facing upwards probably trying to find the sun.  We are headed for a record breaking month of rain.
