    That's a very good point about the number of leaves on a start Pyro. It's a lot easier to start a fire with a torch vs a match. Thought you might appreciate the analogy!

    As to compact medium, I totally agree. My current protocol is to get them established in good loose live LFS, in pots sitting in tray water, in warm conditions. Once the stolons start to make their way out of the pot via drain holes or side holes melted in the pot, I simply fill the surrounding space with loose strands of live LFS. The stolons then become lolons all through the airy moss, which is kept living by frequent misting and occasional watering. I then allow the pots to dry a bit more, which oddly enough seems to stimulate the lolon growth in the more moist airy sections. There is no compaction to deal with at all. Plants are then kept as cool as possible in the summer with a few hours of direct sunlight in the morning or late afternoon. Air circulation via a fan is a big plus to the cooling: the combination of the loose moist moss and a breeze moving through it is most effective, providing good humidity can be maintained.

    Those side holes in my pots are working very well for me! U. alpina now is filling the terrarium it is in. Last year it was a tuber with 2 small leaves.


    If anyone by the name of Homer knows a source for U. unifolia, I have MUCH to trade for a start of it. You might want to pass that on to your source.....

    Meanwhile,my search continues for these most wanted plants. Mr. Jones will not let me rest until I have them in good cultivation. I've only been looking for them since the 60's! Just talking about them makes me jittery.

    I PM'd Homer and he provided the source but when I checked the site all I see listed uniflora. I am thinking that maybe Homer confused the two (as happens quite often) but I am going to check with the source to be sure.

    Well, let me say some things I think from my observations of U.jamesoniana in its natural habitat.

    First, lets not mix species from section Iperua and Orchidioides as they grow in different conditions.

    I think the plants form section Orchidioides can be easy or difficult depending on the elevation the plant comes from. For the highland species like quelchii, unifolia and campbelliana a good drop in temperature during the night will be needed. Without it the plants will grow slowly, become weaker and dissapear in the long term.

    Species from lowlands like U.alpina should be easy and fast growers.

    Last week i got plants of U.jamesoniana from two new locations. One i collected at an elevation of 1100m (3600ft), can be considered a lowland form and i hope it will grow easier than the first form i got. My father coincidentially found another plant when he was collecting some sphagnum for his ocrhids. The plant from an elevation around 2000m has more purple colored flowers but might be harder to grow. time will tell.

    About the dry dormancy requirement, what i have seen is that all habitats will have a drier period with less rain when the plants will get dry but the important thing is that relative humidity will always be high by the presence of nearby water streams or the presence of night/morning fogs.

    Regards.
