Oncidium question

Georgetown, SC(Zone 8a)

Hello Orchid experts!

I have lots of Dendrobiums, which do fine, but this is the only Oncidium I have. It sits outside in dappled shade all summer and grows like crazy. Last winter, I brought in indoors for the winter and put it in bright, filtered light. I've just brought it into the garage as the evenings are getting chilly, which is why in the photo, it's got leaves and other debris. Haven't cleaned it up yet - but you can see how large it is. I got it as a gift in a teacup sized pot.

The question: Two summers and winters have passed and it has never bloomed. Any tips on what to do to encourage it?

Thanks!

I'm hardly an expert and don't recognize this Oncidium but can offer a thought or two. Firstly, most Oncidiums generally like bright light to full on sun. My larger Oncidiums summer outside facing southeast with no shade. The leaves get slightly yellowish. Given the nice green color of those leaves I think it could use brighter light. Oncidiums like to get wet and then dry. They don't like to stay damp. What is it potted in? Are the medium and roots in good condition? Oncidiums often have a wet season and then a dry season to initiate bloom. They are heavier feeders than other genera. Do you feed it? I am thinking the main problem though is not enough light, especially in winter.

Thanks for your help! FIrst, I should say that it was tagged Oncidium, though it's entirely possible it is something else altogether! :)

In the summer it only gets an hour or two direct sun at most. In winter it stays in a south-facing window. It's potted
in standard orchid medium - chips and that pot sits on top of a shallow tray with pebbles and water.

I haven't fed it since last spring. so that could definitely be an issue. I will be sure it gets the most possible light over the winter
and give it a snack more often. :)

Judging from the color of the leaves, I agree with Laurel. Give it more sun.

Doensnt look like a Oncidium or any orchid ive seen. Yeah id try more sun also.

It looks like a familiar FL landscape plant but I can't think of what it is. Maybe if it was posted on the ID forum or Florida forum. I did say I'd never seen an Oncidium like that. Now that could be why it hasn't bloomed. lol

Looks like dracenia leaves but theres no stem. Yeah it might not even flower so you could be waiting a while. hehe!
Is there a pot in the middle of the plant and its growing around it?

I thought it looked like something in the lily family.

Here's the tag that came with it.
Breeindy, yes, there's a small pot and it's growing out all around it.

The only Ralph Yagi orchids I know of are Tolumnias (minis). They are in Oncidium class, used to be called mini-Oncidiums and are sometimes still labeled as Oncidiums. Sometimes growers like Better Gro add a descriptive so the Maroon Spots is not a named cross, but rather the orchid is a Ralph Yagi which has maroon spots. Ralph Yagi is about two inches tall. http://davesgarden.com/community/forums/fp.php?pid=7784030 I have gone back and reread your original post. No way would an orchid go from tea cup size to what you have in two years.

this is what Tolumnias foliage looks like and this is something of what Ralph Yagi looks like but as Laurel said they are small and not that fast growing.

MaypopLaurel and Breeindy: Thanks so much. I had looked up Ralph Yahi "Solar Baby" and found photos but without size references.
The goliage looks alot like that in your Tolumnia photo, but mine is definitely BIG. I originally said it was a teacup sized pot, but it was about a 4-inch pot. Laurel, I think I will take your suggestion and post some
closer photos on the FL forum, just to see if anyone recognizes it there.

It's totally possible the plant was mis-labelled. Since it was a gift, who knows where it came from but I'd bet it was a big box place so who knows! :)
I have brought it into the house now, cleaned up, repotted and ready to winter in a nice southwest window. We'll see!

It would be funny if you are housing a hardy (for your zone) landscape plant in a coveted indoor orchid spot, no? I bet you will get a very fast ID on the plant ID forum. Those folks are genius. Meanwhile, I think both Bree and I seriously doubt the orchid pedigree of your plant. Keep us posted. And, BTW, don't think you're the only one who has ever owned an orchid imposter.

Georgetown, SC(Zone 8a)

Yes, that would be a kick in the pants! :) I have just posted it on the ID forum with a couple of photos and will let you know what happens. If you want to see the
closer photo, here's the thread: http://davesgarden.com/community/forums/t/1285855/

Thanks for all your help.

This really should have dawned on me sooner. I had "tag blindness". Darn tag said oncidium, therefore it must be one. LOL. Thanks Breeindy, I'm off to research guzmania!

Jim, yes! That seems to be it. I shall study up!
Thanks :)
