Oncidium Rosy Sunset 'F'

Oncidium Rosy Sunset 'F'

Oncidium Rosy Sunset blooms with an abundance of tiny pink flowers.  The flowers are very three-dimensional, making this orchid extra challenging to photograph.  It's also the last oncidium that I'll be writing about for a while--although I'll have plenty more oncostele, oncidopsis, oncostelopsis, brascidostele, and all sorts of other intergenic craziness.

Sidenote: Jorge has some stunning orchid photography on his Flickr gallery that is really worth checking out.

Oncidium Rosy Sunset was registered in 1997. It is a cross between Oncidium Pupukea Sunset  and Oncidium sotoanum. The resulting hybrids have varying degrees pink and orange hues.  The clone 'F' which I photographed is on the pink end of the spectrum.  Meanwhile 'Pacific Sunset' has a truly lovely mix of pink and yellow shades that very much resemble a summer sunset. Another clone 'Rosebud' looks like a deeper pink version of 'F'.

Lineage of Oncidium Rosy Sunset

The full lineage of Oncidium Rosy Sunset is remarkably simple.  As shown above, it is a cross of 3 different oncidium species.  Once again, the ever promiscuous Oncidium fuscatum shows up in the lineage (I've also found this species in the background of Oncidium Ron's Rippling Delight, Oncidium Volcano Midnight, Oncidium Irish Mist, and Oncostele Wildcat. I fully expect to come across this species a few more times in the future as I do the lineages of various Oncidium intergenics.
