Oncidium sphacelatum

Oncidium sphacelatum - Flower photo by Richard LindbergToday is the Sonoma County Orchid Society potting party. We will be dividing and re-potting together in a 77 degree sunny day in the shade of a big oak tree. Part of the fun is sharing divisions with the other society members.

Oncidium sphacelatum - Plant photo by Richard LindbergOncidium sphacelatum grows from Mexico south to Venezuela in low altitude rain forest. It is warm to hot growing, but does very well intermediate. It is giant sized and grows long, pendulous spikes of 6 feet or more.

I have some perfect divisions to share. I got a huge, free Oncidium sphacelatum plant in late 2008 and divided it. I tried to sell some but nobody seemed to want them, even at what I thought was a give-away price. I dumped them in a big coconut fiber hanging basket and they have been growing there ever since.


  1. sounds like 100 tones of fun!

  2. It was fun. There was a chance to work together and share orchids.

    When I removed the sphacelatum pieces from the basket, I saw that they had done really well with no medium at all except the coconut fiber lining the basket.
