Trung, I LOVE that Den. antennatum! I was wondering how big it is. How big is it w/o flowers and how big is it w/flowers? Species Dendrobiums are a favorite of mine, even if I've killed more than one. I will still attempt to grow them. I've had great luck with some.

Okay, so is bractiosum a I or a II?
I've been doing intermediate with it.
Do okay but not super-spectacular.
Maybe I've been in the wrong group all this time.

According to the system Rebecca Tyson Northern setup, bractiosum is actually Type IV, persistent-leaved Dendrobium, often plants from high altitude, which must be cultivated all year round in a cool environment, high light (I would imagine above 3000 FCs), but not near freezing. Night temps above 53F in winter and 60F in summer. Watering must be suspended for a brief period of about 3 weeks after the growth period stops (our autumn). Hope this helps.

Hmm.
My plant seems to be deciduous.


Man, I am REALLY in the wrong group.
Or else I am doing something REALLY wrong with this plant!


ack.

That's kinda why I gave up on most Dendros. They always did that to me. Even the Phalenopsis type dropped their leaves then finally dropped the canes! I guess they don't like me

okay, let me re-address that;
The flowes are on the older canes, which are pretty much leafless, the non-flowering younger canes have leaves.

I found it in IOSPE;

and I have the album variety and the flowers look exactly as those in the photo.

So I better change my strategy just a tich, yup.


Thank you, Ross.

OK, I think I have it now, Sammy. Even "persistent" leaved Dendrobiums may drop part or most of leaves during the "rest" period. So even though there seems to be a "rest" indicated, I would opt for continued water, but no fertilizer. The photos suggest this is the case. It seems like the description persistent doesn't mean the same as "keeping every leaf". I do know that totally deciduous means exactly that. See if this works. What you found sounds very much like the moniliforme Dendrobiums.

I got this one dendro that's pretty stankin' huge now and has like a million canes.
Okay, maybe not that many but stankin' huge all the same.
I got to get a pic in here....(still working on the photo upload dealie)....I'm pretty sure it's a Convolutum.
It has leaves on some canes, but not on many others and seems to get blooms on both the leafless and the un-leaved ones.

Lotsa light all the time. It lives on two bricks holding it above water in an ex-bird-bath directly under one of those Bloom and Grow,(two colour), midsize flourescents. It doesn't seem to care what I do.
Always seems to be setting bud on yet another cane here or there so it's constantly in flower.

Den. convolutum is in the Latouria section. I don't have my book with me but I'll check when I get home from work. I believe that most Latourias are warm growers that do not like to dry out. It should probably get a slight reduction in water during the winter just because it's not growing quite so fast. Here's a link to Jay's site.

I think you could probably do anything to this plant and won't care much. They're pretty bullet proof.

Does anyone grow a dendrobium lawesii. I believe its cool growing but past that i havent a clue. It jus sits on its little fern mount and looks at me. hasnt grown in months.I wonder if its dead.
