Thanks everyone
Not detected a scent. I thought I had the other day but I had put it down near the scented Miltoniopsis and turned out to be that.
I've been suprised how well this has done for me as I was a little unsure about it. I have it hanging over the outside of a large plant pot in the bathroom (a large 'jade' plant inside the pot). It gets the light from the window close by which is direct in the afternoon
but comes through frosted glass.
I dunk it daily in the sink. Since the flowers have been open I've been careful to not dunk the flowers.
It's grown roots (although they were good to begin with) a leaf has fully grown and another has started and it's grown and open these flowers.
I should admit that it had a tiny spike when I bought it, but the spike has grown, produced the buds and opened under my care... so I'm taking at least some of the credit
