  1. A red and white xmorei

    Laurent, please could you show a pict of the S. leucophylla. Have you pollinated it with flava or the other side ? Unique, congratulations, Gerhard
  2. Can Anyone Here ID This Native Orchid?

    The flowering time is an important help to differentiant species, for example the simplest method to determinate species in the field, Orchis ustulata ssp. ustulata and ssp. aestivalis, also within the Gymnadenia aggregate und last but not least with the genus Dactylorhiza. Here in Central Europe the Dactylorhiza species show good seperate flowering time: So compared with well-separable species in the same habitat, and the sea level, it is a great help in determining. I know, that same species looks very different in Central Europe and GB, and the prefer different kinds of habitats. So here for example you could never find Dact. fuchsii in open meadows, also it has a different habitus. My first thought was, that is rather a Dact. majalis , because the lip on the open flowers is round, thethickstemsand the leavesvery broad. Typical Dact. maculata doesn`t show such a lip. But in our area you could never find a buded Dact. majalis end of June, also impossible on 1500m nn. You are correct, a good determination is only possible to stay in habitat, to see well flowering plants, comparison is possible with other plants (species ) , for exclude the possibility of hybrids etc. It was simple an evaluation, after an experiance of more then 20 years working with the genus Dactylorhiza http://www.cypripedium.at/product48.html
  3. Bog orchids

    It is unlikely that Dactylorhiza be propagated vegetatively in the bog, because these plants need to share a high nutrient content, which is not available in the peat. Would be better suited Dactylorhiza sphagnicola, which is typically found always as a single plant. I found many seedlings of Pogonia and Calopogon in the bog, it is better situated for generative and vegetative propagation on this soil !

    Then it is the Heath Spotted Orchid, Dactylorhiza maculata

    Looks like Dactylorhiza majalis. When have you taken the pict ? , because this species is flowering in may....
  6. Bog plants

    It depends also from the size of the bog : I would suggest Ledum palustre, Chamaedaphne calyculata, differnt other members of the Ericaceae. Be careful with Eriophorum, the better way is to use Trichoporum alpinum. Some Viola species are situable, but invasive. Very beautiful are some orchids like Calopogon, Pogonia, Eleorchis.... http://www.cypripedium.at/Fotoalbum%20Insektivoren/Hochmoor%202010a.JPG http://www.cypripedium.at/Fotoalbum%20Insektivoren/Hochmoor%202010b.JPG http://www.cypripedium.at/Fotoalbum%20Insektivoren/Hochmoor%202010c.JPG
  7. Miniature Arisaema sikkokianum

    I expect it`s rather a first flowering seedling then an offset ! Here is small part of my Araceae collection, also a pict of a man mad hybrid of A. sik. and a F2 hybrid http://www.cypripedium.at/news_15.html
  8. Miniature Arisaema sikkokianum

    A. sikokianum is a species which doesn`t produce offsets ! So it`s only possible to multiply it through seeds. Probably can spare seedlings/ FS tubers
