Yann
lovely to see in the wild.
Steve they are little beauties,not something I have tried.
As to the dactylorhiza I bought some small seedlings some time ago and now have half a dozen coming into flower. The leaf markings are very variable but I cannot comment on flower colour variation yet. Dactlyorhiza thrive with me,almost a weed from self sown seedlings in the garden and pots and the listera has been thriving in the garden again self sown for some years.
I am going to propagate the D. baumannii by taking of the tubers in a couple of weeks in the usual way.

Well here's my contribution to the terrestrial orchid thread.
All I could find after my Dog discovered he likes the taste of dactylorhiza (he's gone right off mobile phones) ...
They were like that when I found them ...

Hi John
A frost free greenhouse, as they will not survive outside in our climate. The mixture I use is as follows 1 part perlite, 1 part fine horticulture grit, and 1 part a sandy soil, with no organic matter in it, it needs to free draining mixture. They can be planted up now, 2 to 3 cm deep, but do not water them until, the end of August beginning of September. Then careful watering is required around the edge of the plant not on the leaves Once the leaves start to yellow in the spring stop watering. The easiest way to kill them is to over water them.

Hi Neil thanks for getting back to me, would cactus compost be ok as that is really free draining and I can mix in some perlite.

I would presume so. The idea is to keep the soil moist and not waterlooged

John,
There is quite a lot of organic matter in proprietary cactus compost which might encourage rot.
I would be inclined to avoid this. Make up your own mix based primarily on sharp sand (coarse gritty sand), add perlite by all means but don't add any more than 10% organic material.
As Neil has advised these are winter-growing plants. They need moisture when in growth and then need to be kept dry as they go dormant.
It is difficult to keep a pot plant that is grown in pure sand moist at the root over the summer which is why most of us add organics to our alpine mixes. This isn't a problem over winter as long as your greenhouse doesn't get too hot.
Ophrys grow well in gritty sand as long as they receive regular dilute feeds. Very few ophrys are lost due to "starvation" or lack of water over Winter -the vast majority die due to collar rot or root/tuber rot in the first half of the growing season.
Think inorganic when growing terrestrial orchids. How many times do we see Dactylorhizas self-seeding into lean gritty troughs and thriving with very little organics?
The main function of organic material in potting compost is to hold moisture. For the organic material to nourish plants it really needs to break down -such a process occurring in a pot often inadvertently creates an overgrowth of harmful fungi & anaerobic bacteria which then encourages rot. I am not a soil scientist but I have no doubt that the recycling of organic material in the open garden is a very different process to what happens in potted soil.

I didn't know that about Cactus compost containing organic material. I just assumed it would be inorganic.

I didn't either Neil, I thought with it been really sandy and gritty it would be ok

I love it when plants just arrive in the garden of their own accord (well, most of them). This has appeared in a half barrel full of water loving iris. ID please!
ID suggested 18th June:
Dactylorhiza fuchsii
(Common spotted Orchid).

It is a beauty. I bought it in flower from Ardfearn at an Aberdeen show a few years ago and keep hoping it will flower at that time again but it never does. It looks promising but the buds take ages to develop.

Roma that is lovely. Mine is not through the ground yet-but not dead!
Dactylorhiza 'Eskimo Nell' in the frame. The ones in the garden are in early bud.
