I was given some tubers of Pterostylis curta, which seem to be doing rather well.

They are doing well - and in January - how lovely!

In flower on the windowsill:
Ophrys cephalonica
Ophrys cretica
Ophrys phaedra (probably Ophrys omegaifera)
and an unknown species of Ophrys ex Cyprus. (Ophrys elegans, thanks for the determination to Stefan)
-
Ophrys "phaedra" is probably O. omegaifera and the species from Cyprus is Ophrys elegans.
-
Stefan ID is perfect :)
By the while Wim, is there a microclimate in your house ?

Flemish rivièra, Yann...come and live here, we have wonderful weather every day of every year ;)

yes excellent weather :-\

Ophrys kotschyi -First Ophrys in flower here, they have all suffered a bit from the recent hard frosts.

What a lovely way to start the year, one can do a lot worse than looking at your brilliant photography and the plants aren't bad either. ;D
-
Ophrys sphegodes, very early this season.
Steve do you heat a bit your greenhouse?
-
Nice plant Yann!
I try to keep this greenhouse frost-free by heating and by closing down ventilation -but I’m not very good at it! I often forget to open up the vents and so if the sun shines next day the greenhouse can get quite warm. Having said that kotschyi is the only one to have flowered so far though speculum is not too far behind.
-
ok, i keep mines at 4°c.
kotschyi is always very early in the wild.
-
The Ophrys are now in full bloom, the common Ophrys omegaifera and Ophrys cretica ssp ariadnae

Dear Hardy Orchid Growers,
We are doing research on bulbous plant viruses, mainly potyviruses and cucumber mosaic virus. I'd like to get in touch with hardy orchid growers Europe-wide who might have suspicious plants, both winter green and summer green species are interesting for us (including Pleione). I know, that most of you are working hard to keep your precious collection free of such diseases, discarding the plants as soon as you have suspicion. Next time if any of you see a suspicious plant please do not throw it away, but separate it from the rest and contact me by PM with a picture, because it can be interesting for our academic research.
For virus symptoms there is a collection of demonstrative pictures on the website of Paul Cumbleton http://www.pleione.info/pests--diseases.html (http://www.pleione.info/pests--diseases.html)
We need intact plants, because we will carry out several tests (including Transmission Electron Microscopy, PCR, inoculation of virology test plants) during the upcoming months. Samples are welcome whole year round, when there is no risk of frost, as freezing and thawing of plant material is bad for virus isolation. Samples will be planted at the virology glasshouse of the Hungarian Academy of Sciences. We keep all our sources confidential!
With Best Regards,
Janos

Nice pictures Steve, as always :)
I was wondering, have you tried soils such as pumice, akadama or kiryu for ophryses?
-
Thanks Julien.
I use a compost mixture comprising of pumice (3-8mm) with “Seramis” (actually I use a form of cat litter) and coarse perlite. I make up a 50:50 mixture of micro-waved loam and Scots Pine leaflitter and add a small amount of this (10% of final volume) to the pumice/cat litter/perlite. Finally I add some powdered dolomitic lime. I now get much less tuber rot and as long as I give a regular light feed the plants do well. I suspect that Akadama would work just as well, especially if mixed with a small amount of limestone grit.
-
Thanks, will try next year :)

Many thanks Chris and Herbert.
Changnienia amoena: I got this from a German vendor as a small tuber 4 years ago. I grow it in shade on a shelf under the bench of a cold greenhouse. It is in a compost comprised of Sophistocat cat litter/perlite/pine bark and pine needles with a small amount of proprietary ericaceous compost added. It is kept moist over the Winter and is gently dried off in late Spring when it goes dormant. Like Calypso it requires a little Summer moisture to prevent dessication. It also needs protection from marauding molluscs and other nefarious wee varmints.

Nice pictures Steve and I like Changnienia amoena most.
The last one looks more like Ophrys picta and is surely not Ophrys oestrifera, neither s.str. nor s.l..
-
Many thanks Stefan.
I think I have the wrong names for a few of my Ophrys. I lack the expertise to sort this. ???
I will change the label.
-
Some of you may find this an interesting read
https://academic.oup.com/aob/article/121/1/85/4796793
according to the DNA analysis, there are only 9 Ophrys species.
-
Nine seems about right, but my friend now calls me a "Lumpernazi" so I would say that.
-
according to the DNA analysis, there are only 9 Ophrys species.
You may believe that I definitely don't.
Other more extensive (and much more expensive) DNA analysis show a high correlation with the biological approach (pollinator).
-
Except that it depends on which definition of the species you take, the genetic variability inside a species can be greater than the differences between alledged different species... And there's an annoying tendancy among ophrys taxonomists to describe each local form or even lusus as a new species!
Facts remain, there are only 9 or 10 groups among which "species" are fully cross-compatible, cross apifera group with insectifera group, the hybrid's pollen will be sterile (same with spehgodes, same with scolopax)... but individual "species" in each groups are fully cross-breedable, where do we draw the line between local diversity among a species and different species themselves?
-
I think that "the splitters" often forget the soil's nature and microclimate give local "species" features.
sphegodes is nice case of variability, all DNA analysis gave the same result.

ficalhoana usually produce many bulbs, one my best increaser.
prisca is Orchis spitzelii?
-
I started with one ficalhoana bulb and now there are three. It is prisca not spitzelii.

Steve, nice pictures as always. Your Orchis simia is probably a hybrid with Orchis militaris: Orchis simia flowers from top down and the arms are too broad. But it is a very nice plant.
Serapias cordigera is my favorite Serapias.
-
Thanks Stefan.
I would agree that my “simia” seems to have some militaris features. I bought it from a grower in Germany. I also bought a “purpurea” from the same source; it is now in flower and is clearly militaris. I would like to track down some cultivated pure simia and purpurea -if you know of any sources please let me know.

Steve, thank you for the education (and superb photography!). Until now, I had no idea that yellow Dactylorhiza existed!
-
Hi Steve,
so nice to see a Dactylorhiza sambucina. Is it your plant and if so, how do you grow it?
-
Hi Maren,
The sambucina are pot grown in a mix of pumice/perlite/grit/cat litter/JI3 (equal proportions of each). The pots are plunged in sand in a covered but open-sided frame. The sand plunge has heating cable set to keep the plunge just frost-free. Previously I grew these Dacts along with Ophrys in the greenhouse but found that they coped poorly with the low winter light. When grown in a cold frame they come into growth in late March. The good light levels/long growing days of late Spring seem to be appreciated. Unlike native Dacts they don’t tolerate a wet growing medium.

I loved seeing the dactylorhizas in the bulb log this week. Like yours, my garden is full of self-sown seedlings in fascinating variety. Those, and epipactis, certainly get around.

Not much to see in the garden now after the drought, basically only a few surviving Epipactis veratrifolia and Bletilla "Coritani" flowers.

Butterfly Orchids
Apologies…. I meant to post these photos ages ago…..
I’ve been wandering up & down Wharfedale for half a century now… and never seen these fellows before.
One evening in late June I rolled out of a pub with my brother & Co.. We wandered back to his holiday accommodation in falling light… and there they were.
Everyone else was keen to get home. I would have stayed longer… but as it was… a SIGNIFICANT number of horseflies were killed in the taking of these photos!!!!!

Hi Steve,
Where did you get Thelymitra?.
I want to buy some tubers
-
Hi Ian,
I got my plants from Dr. Heinrich Beyrle. He offers an extensive range of species and hybrids. I’m not sure if he will ship out of the E.U. as this may involve CITES paperwork. You can contact him through his website: http://www.myorchids.de/main1.htm (http://www.myorchids.de/main1.htm)
