This is the only oncidium I own unless tolumnia are now oncidiums. In that case I own two.

Wow!!!!!!!!!!!!!!!! I have one of these and maybe get 2 or 3 spikes. How do you grow it? Is it hanging in a basket? What do you have it potted in?

Hi,

It is potted in a 12 inch shallow (bulb pan) plastic pot and hangs in the cooler end of my intermediate greenhouse. 30% shade in the summer full sun in the winter. Media is a medium coconut husk mix with 50% non organic components which include lava rock, clay balls, and sponge rock with about 5% medium charcoal. Fertilized at about 250 ppm total dissolved solids once a week most of the years with a top dress of 1/2 tsp slow release fertilizer in spring. Watered twice a week with rain water with occasional additions of either calcium nitrate or magnesium sulphate.

I hope this helps. If you have other questions, feel free to ask.

Absolutely gorgeous! On my list of wants.

But if I remember correctly, in the '70's, oncidiums were a huge variety with mini oncidiums and rat tailed oncidiums and mule eared oncidiums. I don't know when they broke the species up.
 
Thanks for the info Chuck
I am going to repot mine and hang it up so it gets more light.
 
The fragrance coming off that plant must be heavenly! I have one called 'Lilac Soap' but it doesn't smell like lilacs at all; its scent is reminiscent of stepping outside on a cool humid spring morning and breathing in the fresh air!
Gorgeous plant Chuck, and beautifully photographed.

I just have to say thanks for the info. I repotted my ornithorynchum into a basket with a similar potting mix (bark instead of coconut husk)as yours last November and hung it up in the top of the greenhouse. For the summer it has been hanging outside under the shade of a tree, so it gets pretty good light. Usually it only bloomed for me in January, but right now it has three spikes, which I think is a first.
Again thanks for the info. (I will post a picture when it blooms)
