coelogyne marmorata or any warm coelogyne growing tips needed - Orchid Board

mjr092 · #1 08-28-2006, 05:11 PM

Amazingly little info on the 'net on this species; doesn't sound like too many people grow this one, but giving it a shot here anyway. I think it's a 'warm' variety. I'm guessing, b/c fr what I've read most point out the cool growers and marmorata is never identified as a cool grower so it must (likely) be warm If you are a grower and have a coelogyne and it's 'warm', well, what season does yours bloom? I've heard conflicting things about watering? Should I keep it moist or let it dry out in between. This one is native to the Philippines, I don't know what elevation and elevation is meaningless to me anyway for light requirements & temp b/c its in meters and I have no frame of reference. (I don't know what the h*ll we don't use the metric system when the whole world does and I have to *!&@ convert, but... I digress). I live in TX so I get as much light as I want, and can manipulate the lighting as needed, and this baby will be indoors on a windowsill. Aside: I heard this genus hates repotting and gets sulky about having its roots touched but really hate it's ugly green plastic pot, can't tell if the roots underneath are healthy but don't wanna chance it. So, any info-feedback-comments on this genus/species are welcome

I haven't tried to grow this one but found this information:

It appears that it is fairly tolerant of temperature variation........

Temperature thing is good news, because I can't accomodate too many growing variations among the plants. They have to be forgiving or they have to go. Thanks again for that link. And that flower is gorgeous!! I hope she likes me and flowers like that...

Hi Mimi,
Most of the Ceologyne's tend to be a bit forgiving in regards to temp, we grow about 20 different species, unfortunately Coel marmorata is not one of these. We do however grow Coel chloroptera which has a lot of the same attributes as Coel marmorata ie. it grows in a lot of the same areas in the Philippines at around about the same elevation 1000 metres plus(1000m = 914yards roughly speaking) both grow as epiphytes (on trees) & lithophytes (on rocks) and both come from the same section of Coelogyne that being Lentignosae.
As for temp we grow these in an unheated G/H which can get down to 2C (36F) in winter, and up to 35c
(95F) in summer. In winter this would only get watered once a week, and in summer 4 times with misting on really hot days to cool the air.
We flower it in late winter early spring and I am quite sure it is the same for Coel. marmorata . The spike arises from the centre of the new growth and this is consistent with all the plants in this section.(Lentignosae).
We have 50% shade cloth over the top of the G/H and the Coel chloroptera is quite happy growing in a shady part of this house.
As for the marmoata I haven't been able to find one of these for myself yet, but its only a matter of time before that changes, someone is bound to have one some where round here (Oz). it is a very handsome flower so get that thing flowering and post us a

ASAP.
All the best Craig

Hi Craig, THANK YOU

for sharing that detail and growing information. I now have a little more confidence with how I should grow my very first species plant. Looks like I'd have to try hard to kill it given how it can accomodate such extreme temp variations. When it blooms I sure will post a picture. Right now it is in a 3.5" pot with 4 established PBs (2 very shrivelled looking, I guess they are the old, back bulbs) and the 2 new ones have these long papery tapered leaves about 20" span on both. All in all a very pleasant plant to look at even out of bloom. I am infatuated with Coelogynes and I would like another at some point. I can hardly wait to see those delicate transparent flowers when I get it to bloom. And, yes, I will make it bloom with these addt'l recommendations. It can go in the shady part of the grow room (with the new Aerangis that I'm expecting in the mail and will be mounting on a wooden slat). I feel a little embarassed that i have nearly 15 plants and I've just started a month ago. But it pleases me and the plants are happy. Synergy. And I have a big empty house so I got the space and the light. Woo hoo. Want more orchids.

I am in a position to obtain a Coelogyne ovalis in the next couple weeks from another grower far far away in the Great White North. I can't believe how quickly this has become an addiction. Its like a fever. With my collection I will now stick to unusual species and miniatures with easy culture requirements only. I think Coel. will fit those requirements.

When I find my camera somewhere in these *%@! boxes I'll post pre-bloom and blooming pictures of my coel. or I need to put it in the grow blog that I haven't started yet. This thread needs action, Craig or other growers, why don't you post your pictures if available, so we can ooh and ahh and be inspired.

This is a spring bloomer, but it also bloomed for me in the early winter.

dave b · #8 05-06-2007, 11:31 PM

Coelogyne is one of my favorites.

Attached is a pic of my speciosa. its still in bloom, but the flower is fading away. The secondary bud is swelling and looks promising. Last year, only the primary bud bloomed. There are 2 more spikes behind this one.

Also attached is a massangeana i purchased recently. Im not supposed to be buying big stuff do to space, but the seller cut me a deal, and i couldnt pass it up. When it someday blooms, ill post pics.

My Coelogyne velutina is warm growing. It des not like direct sunlight as the leaves burn easely, in fact the leaves likes to be sprayed often as they have cells in the leaves that will absorbe the water. I keep mine moist all of the time, and of what I can understand I likes a lot of fertilizer as it is a fast grower. It likes a lot of water, but it does not like soggy conditions

MiMi,
Coelogyne marmorata is an easy species to grow and flower. I grow mine in a greenhouse with all my other orchid species. Temps range from about 5C on a really cold winter morning to about 36C on a hot summer's day. I grow it in a clay pot in pine bark (Pinus radiata) topped with a layer of sphagnum moss. I grow other Coelogyne species as well but they are scattered throughout the greenhouse. Coelogyne speciosa and Coelogyne fimbriata coming into flower now. Coelogyne becarii and Coelogyne tomentosa (syn Coelogyne massangeana) just finished. A botanist in the Netherlands has done some work on the Coelogyne fimbriata group and she has sunk Coelogyne ovalis into Coelogyne fimbriata as well as another (?Coelogyne fuliginosa). I think that they are different. If I can figure out how to do it I will post a picture of my Coelogyne marmorata.
Keep well and kind regards
Mike
