Oncidium sphacelatum 'Marion'

Oncidium sphacelatum 'Marion' - Flower photo by Richard LindbergOncidium sphacelatum 'Marion' - Plant photo by Richard LindbergThis Oncidium sphacelatum is potted in bark in a 4-inch plastic pot. It has three pseudobulbs and one new growth and stands 12 inches above the pot.

As far as culture goes, I consider it a beginner plant, but not a good indoor plant because of the plant size and the length of the flower spike. This is about as small as a flowering sized Oncidium sphacelatum can be. This was a raffle prize. I selected it from a group of orchids that were not suited to my collection. It is a duplicate.

Oncidium 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.
