Years ago, we used to sell it as a temporary houseplant, so you may want to try tropicals suppliers.

Have you looked at the RHS plant-finder to see if it is listed.

Thanks Tugbrethil. I've searched but nowhere seems to have it. It used to be quite common.

Thanks Eileen, but it does not name any suppliers.

Thank you.

Hywel, may I have permission to use your photos of Rhipsalis pilocarpa that you posted in 2016 for a plant society newsletter that I edit?

I don't mind you using my photos.
Here's a link to another photo of the same cactus with a red berry which come after the flowers fade :-
