This one is a keki I took from a plant that my mother has.
It bloomed right in the first year (this is the third year I have it) but it gives me only one flower each year.
I don't know it's name so I call it "Van Gogh".
This one was an offer two year ago. It blooms profusely, this year it is blooming from a new spike and also from spikes 2 and 3 years old.
Last year I've contacted the vendor in the Netherlands... he asked me for photos and everything but never replied with a name for it.
