March 2011 in the Northern Hemisphere

[YT]

Hi all, here are 3 variations of Viola mandshurica.

Viola mandshurica: a large flower form with broad petals
Viola mandshurica: a F2 selection from “albino form” x “large flower”
Viola mandshurica f. plena: a multi-petal form found from a wild population

--------------------------------------------------------------------------------

Really nice and well grown plants -
Due to my preference for these species I admire the violet especially!
Gerd

Thanks Gerd, I hope you enjoy this time too

Very nice white forms YT 

Nicole, there is an another white form, thanks

[fleurbleue]

 YT they are so cute all  and always, my first choice is mandshurica alba

Tatsuo,
very nice cute violas. 
I prefer your 1st. image Viola mandshurica.
Very lovely.

I hadn't seen a plant of Lathraea clandestina for ages but saw lots of it in Mount Usher Gardens, County Wicklow, yesterday. It is a fascinating plant.

Tatsuo,
very nice cute violas. 
I prefer your 1st. image Viola mandshurica.
Very lovely.

So do I!  Once again I admire  well cultivated specimen. Its difficult for me
to achieve these amounts of flowers from Japanese species.


On this occasion I add some photos from here

1. The hybrid between Viola alba and V. chelmea - from Greece
2. Viola jaubertiana - from Mallorca/Spain
3. Viola xanthopetala - from Russian Far East
4. Viola odorata sulphurea - a variant from the normally blue coloured
    species

Wim, I am no trillium expert, but your T.sessile true looks like the plant I have as T. petiolatum as the leaves have distinct stalks.

Thanks for the compliments Paddy and Ashley.

Hi Wim is that Trillium albidum it looks very like the onw I have under this name?

Ian,

it's not Trillium albidum. T. albidum is completely white. This is a hybrid, being correctly sold as "Trillium western sessile hybrids white pink base".

According to Case albidum comes in two forms,one pure white to creamy white the other soft pink-rose near petal base particularly in plants from the northern Napa Valley regio, mostly plain white in northern California and Oregon'

I grow both forms thogh I bought one as purple stained throat but they both fit Case's description

That was my thought too. I think the term sessile is used quite a lot as a generic meaning only the positioning of the flowers rather than the species. I bought a T sessile many years ago now a lovely garden weed which is most likely a form of chloropetalum

I agree that it is probably a hybrid with chloropetalum genes in it. Maybe the name under which it is sold is confusing but "Trillium western sessile hybrids white pink base" just means that the flower is sessile not that it has T. sessile as a parent. I have the true T. sessile here too but that one is very different from this plant. (Pic here attached (taken in 2009) is true T. sessile).

Hi Wim,

The 'Trillium sessile' in your picture is definitely not.  It looks most likely to be T. recurvatum.  T. sessile does not have leaves with a pronounced petiole like those.  See here for a variety of T. sessile -

All the best,

I understood Wim to be calling/ having sourced his trillium as a sessile hybrid.  
I do not see any leaf petioles in his picture, as John L. mentions :

T. sessile does not have leaves with a pronounced petiole like those.

I'm confused....
So I'll  repeat  the picture here, to allow a closer look without dipping back three pages....

[ashley]

 

No petioles but a wonderful trillium.

[Maggi Young]

Aha! I think I have realised the source of my confusion ( there's often a clue, thanks John!)

 John was referring to this picture,
      ....not the one I thought!
 This one, claiming to be T. sessile,  DOES have the petioles
 And is thus  presumeably T. recurvatum

[annew]

There's often a clue...

[Maggi Young]

There's often a clue...

So true, Anne, if only I could find them a little more easily!

Just opened today, one of my favourites, the single form of Sanguinaria canadensis.  More delicate and even more fleeting than the more commonly seen double version.

Hi John,

many thanks for the correction. I was slapped on the wrist by another Trillium expert today for naming a T. recurvatum as T. sessile.  I bought it a couple of years ago as Trillium sessile but that does not excuse  me; I should have checked more thoroughly. 

Cheers
