    The flowers are 1.25" wide. It is about to be overtaken by this moss--the bane of my greenhouse for several years now. Makes me nostalgic for slimy algae.

    Nice deep pink color on that one and good flower size too. I love it!

    What kind of growing medium in the pot? How often do you repot it? Thanks.

    Nice Marni.

    I like the moss, but it does get out of hand in a hurry.

    This is growing in NZ sphagnum. I don't grow a lot of things in moss, but these do quite well. I also grow them in a 50-50 mix of tree fern and pumice in a small net pot set inside a plastic pot. Some times in fine bark mix. The also do pretty well mounted on cork or other hard wood.

    How often I repot is hard to say. Ideally, it would be once a year for these as opposed to most of my potted plants which are 2 to 3 years for bark mix. Some of them can go longer with no trouble, but with moss once it starts to go, the roots are lost.

    For the last few years this awful moss has been making me try to stay to the 1 year to 1.5 year mark. I do spray the moss to kill some of it, but it comes back. It seems to suffocate the plants and I have had a lot of loss because of it. The water doesn't penetrate (even with wetting agent) or it stays way too wet because the air doesn't move through it. Either way it is bad. I fell much better now that I've vented about the damn moss.

    With moss killer. Safer makes it. I don't spray the whole plant or bench, but spray around the base of the plant. It takes a couple of days, but it kills the moss and you can pull it off without taking 1/2" of potting medium. It is gratifying, but a bit ugly. It leaves a brown spot that is reminiscent of dog pee on your green lawn.

    I would be a very happy woman if I thought I could run it through my proportioner and get every bit of it.:)

    lol. yea, that is way too much work. Ill pass. I will just go the old fashioned route of pulling it out. I do like the way it looks, but it needs to be a constant as far as pulling it off mounts and out of pots.

    OK, enough about moss. If I feel the need to vent about opossums I'll move it over the 'Pets and Wildlife' or 'Issues, Disease and Pests'.

    Very nice Marni...

    Now that I have proven to myself that not only can I grow these I can get it to flower too ;) I would like to get a few more of the other more color variations of this one. As a matter of fact I remember seeing a picture of a white one that was just out of this world...any one know where one can be found?

    Forgive me but....who pulls the moss off in the wild (birds)? I mean, for these cloud forest types, aren't the branches they grow on covered in dense drifts of moss and lichen, usually? Why does it not have the same bad effects? Is it really just a problem with potted orchids? I can imagine that on a mount (branch) if moss starts to get out of control a root could just grow through it to the other side of the mount/branch but not so much in a pot. :confused:

    I have killed several of the white or creamy yellow ones. For the time I have stopped trying them. I think some are in flask around the Bay Area and will try the whites again when they become available. You might check with Dan Newman of Hanging Gardens. I don't know that he has whites available, but he does have other color forms. Mountain Orchids used to have quite a variety, so you could check with him, too.
