The Pleione arunachalensis is superb Vigor.
Is it easy to grow?
Will it ever become available commercially?

Pleione albiflora

Another stunning display Steve.

Some more flowering here :

Pleione Marion Johnson 'Bubs'

Pleione whakari 'Dune Lark'

An unnamed Anthura hybrid - could be P. 'Burnsall'

Pleione Glacier Peak

Pleione Michael Butterfield 'Crowned Eagle'

Hi There,
The season has opened here with P. Follifoot ‘Princess Tiger’. Not one of my favourites, but reliably floriferous.

I know the topic comes up repeatedly but I wondered if you could help me identify pleione with virus. I know colour breaks are important but I can also see how pigment is naturally patterned sometimes on petals.

I’m attaching a few pics and would love it if people could help me work out if these have a viral infection and I should destroy them.

Sorry about the scribbles. I’m in a hotel room trying to do this on my phone

From memory they are

Sirena
Edgecombe
Shangtung Ridgeway

1 and 3 are clearly viral, for the 2nd one it would be easier from another angle (this one is seen in transparency, doesnt really allow to determine whether it's factually pigmentation or texture)

Julian

Thanks for getting back.

Here are other angles and close up of flower 2- the final pic does look like a colour break.

Is the only course of action destroying the others? They are very robust plants etc. Does their virus affect other orchid species?

Thanks Paul

Unfortunately, I'd say it is also viral

It is true that pigmentation can be naturally patterned on the petals and sepals, but in this case, the patterns usually are mirrored between corresponding petals or sepals and they have a regular shape, not random "watermark" type.

There is unfortunately no cure for virus so far, and it effectively doesnt seem to affect the vigor of the plant, however it is highly contagious and spreads really fast to a whole collection, which is why it is advised to destroy suspicious plants, or at least keep them totally isolated from others.

According to Karel Týbl who isolated and described this virus (PlFBV) it can easily infect other orchid species in mixed collections...

Pleione forrestii

Thanks Paul.
I also have a white form with violet lip markings which hasn’t flowered this year.
I find forrestii -especially the white forms, to be the most inconsistent and problematic of all Pleione species. With me forrestii is prone to fungal attacks and rot whilst the flower buds abort very easily with temperature fluctuations (something that is difficult to avoid under glass especially if days are sunny and nights are cold).

Tell me about it, the only time I actually had forrestii flowers for me was in the fridge until the flower was open...
I also find that despite the usual advice to grow it on mainly moss, I had less fungal and bacterial issues (in my growing conditions) on totally mineral mix (kanuma or even leca).. of course it forces me to water a lot more in summer
