Himantoglossum robertiana ( formerly Barlia robertiana).
This chunky fellow started to flower on the 6th. I think a little early even for this species. I appear to have the greenish white (pinkish) variety and I am hoping another variant still to flower.
Very nicely scented large flowers ( for this type of inflorescence ) and you have to admit he looks happy :D
Woo hoo, the new season has started ;D

Hi Fred,
a beautiful plant you have there. Maybe it is flowering a bit later in the wild, but it mostly depends on the temperature you provide your plants. An early flowering are my Ophrys speculum which are flowering since three weeks now (at least some of them), but that does not disturb me at all. :) I will just have to let them go dry dormancy earlier too.

Cold greenhouse with vents full open all year ;D
Nice Ophrys BTW ;)
-
No heat?
Mine is also in the greenhouse and louvres open all the time but the plunge is heated to 5C

Very nice !
Do you grow them outside Chris ?
-
Fred very nice and very early, 1 of mine is just showing a spike.

Hi Kris,
answering your question. No I keep my Mediterranean orchids indoor in my basement. It is suitably cold but only when the temperatures outside are not around 4*C at night and 8*C during the day, which occurred not that long time ago. Normally I keep the temperature in range of 3-5*C. When there are no frosts outdoor I open a small window so that a fresh and cold air can come in. They are with my carnivorous plants on a shelve I made with an artificial light. I lighten them about 12 hours a day with light of strength 4 x 40W + 5 x 18W from a distance of about 20-25cm. Next year I intend to add another 2x40W and 2x18W lamps. Than all the plants should be given equal amount of light to grow perfectly. I was always lightening my carnivorous plants, I just improved it this year and add additional lamp for the orchids.
Unfortunately, a green house is yet impossible for me to have. I made one once, but I could never afford heating it up. Especially when there were three weeks of -20*C last year in my city. I made than experiment, before I have been given the orchids from my friends, to test if I am able to keep a proper temperature with cheap means. I failed severely. The elements I used to make the green house now serve as a skeleton for my basement shelve. In the future... I hope to have an outdoor rock garden for Mediterranean orchids, which will only be covered from rain and from frosts during the winter. :)

I didn't think robertiana could stand much below 0oC? I kept mine frost free.

Very interesting to read how you mannage Chris . Thanks to share your experience !
And the results with the speculum are very good indeed.

There's been a good spell below 0ºC before Xmas and that didn't appear to bother them as can be seen with the flowering. We are forecast -14C over the next fortnight or so so I'll be keeping a close eye on the thermometers.

Kris,
I really didn't put there any useful information. Believe me that when I will gather enough information and gain a bit more experience with those plants I will share my results. The thing is I already describer quite some about some fully hardy European orchid species. Unfortunately, I didn't have much time to translate all of them. But I have much more Mediterranean orchids than just Ophrys speculum. The problem is my friends made me a "students mix". They gathered quite some bulbs of many species and gave them to be just like that. I have NO idea what I have and where it is. I have an idea about the species, but which one are which I don't know. Until they flower I can just suspect. What is troublesome, there is still about 70 more waiting for me. I just didn't not know where I will put those... But I will have to think of something. Not often I am made such offers it would be unwise to refuse. :)
About Barlia robertiana (which name I prefer). Depending on where it comes from it can withstand frosts down to -7*C. At least it what I heard it has in one place in Portugal. I know that some plants can withstand more than we suspect, but because they are rare, beautiful and expensive, it is unwise to experiment with them like that. Especially when we have other means of growing them than outdoor. Beside, there are quite many interesting species, that can withstand -20*C, so why to force those that cannot?
If my knowledge could help anyone, I will be glad to share it.

I checked the temperature records for here. So far this autumn/winter we have had 16 nights at 0°C or below with a minimum of -6°C. I think my experience is backing up what Cephalotus has heard ;D
Just to throw another hat in the ring, no matter what our opinions are of taxonomists, should we use names we prefer or ones that are correct? ( Steps back behind the lead screen)
-
Fred
what is correct,it is only an opinion. This is an endless discussion that never gets anywhere. I just leave my labels alone and wait for the name to come around again hopefully before I or the plant passes on.
-
Fred,
I subconsciously forced this topic about naming plants, or lets narrow it just to orchids. It is like Tony wrote, it is never ending story and discussion, that rarely leads to anything helpful. I wrote a long answer with some examples, but there was so much of it that I do not want to overwhelm the topic with this off-topic. I have wrote you a PM with my previous writing and a few examples.
-
I can see a bud coming up on my B/H robertiana
-
A few more photos as the inflorescence continues to bloom.
Clone 2 is starting to open its flowers,which are not as noticably scented as the original.
-
Have I got this right, Fred? - the second clone is in pic 4, with more pink in the flower and less scent?
This suggests that a brighter flower has less need of fragrance..... :-\ ???
-
Yes Maggi pic 4 is clone2.
Insects don't see the colours of the flowers as we do so I'll leave that one up to you :D
-

Yes, I know - so it really is a mystery , isn't it? Always so much of interest.

Maggi
I think the two clones are about on a par now with scent. On the one day since the 6th January that the sun managed to stay out long enough to hit then greenhouse they filled the whole place with their scent.
Being winter flowering the inflorescences last for such a long time too.

Thanks for the update , Fred. A sunny greenhouse full of scent- that's a prospect that gladdens the heart, even if you had quite a wait for it!
-
Several weeks after Fred's my Barlia has started to open and like his the scent is filling the greenhouse. Colourwise mine seems to be a cross of his two clones!
-
Here also still in Flower.
-
My Himantoglossum robertiana is now in spike, a bit short only 110mm at present, but a beautiful when it is warm!
-
Just a little update.
Three mionths later.

Three months later.
Now that is a long lasting flower spike. 8)
