Hi Susanne ...I have this orchid.
Rhychovanda Colmarie 'Fred'
Beautiful colour and always gets peoples attention when in flower.
I have a picture on my orchid page of my website.

I grow it in a greenhouse with the cattleys. I do however have an alsonite roof over the vanda section. (Clear waterproof solid plastic)
I also put ordinary clear plastic around the shade cloth in winter to make it warmer. I mist to help with humidity.
In summer when I know it is going to rain I hang this orchid on the washline and let it get a good drenching.
Fertilizer is weakly weekly.
About the end of autumn start with a bloosom booster fertilizer.
This is how I grow it... but I guess it all depends on the climate one has. I have sub-tropical.
