Rhipsalis campos-portoana

Epiphytic forest cactus from south-east Brazil ...
Rhipsalis campos-portoana :-

 

I don't give it any special treatment, it is potted in ordinary compost. In the summer I put it in a Perspex shelter and in the winter I bring it into a heated conservatory. It gets water when I remember to give it some, and I hardly ever feed it. I am always surprised when it flowers ​

 

Wow, that is impressive! I remember in the 80s all my friends used to grow it as it is so unusual looking plant, and very easy to propagate... but I have never seen a flowering plant. Well done @Michael Hewett

The flowers look a bit like snowdrops don't they?

 

Thank you @Selleri , I have several different types of these and many of them flower.
Yes they do resemble snowdrops
