I'll pile in with a regular pink one. No UV photos, I'm afraid.

Thanks MikeDom.
A useful comparison photo.
When I took the label out to replace it, there was "v. senilis" hidden below compost level.
Did the original owner miscopy the name onto the label or did I miscopy the name when I replaced the broken label?

Terry,

A properly blue cactus flower at last! If only it was that colour when illuminated by daylight :grin:

What does Echinocereus viridiflorus look like under UV?

If I had the plant, which I don't, I would be able to tell you.
What colour is the flower, and any variants of it?

It’s a light green or some times green/brown or lemon/green colour. I guess I could put some batteries in my old stamp inspection UV lamp and see what it looks like when it flowers. It’s often lighty scented as well.

Similar to a lot of Echinocereus, it has spines in an array of reds, whites, blacks, greys and browns..... how do spines behave under UV?

Sounds promising. Mid spectrum (green) to high end (blue violet) are able to fluoresce and produce a visible output. Yellows are not usually productive, similarly reds, and yellow Lithops seem not to fluoresce with the frequency light which I have. Brown and grey give surprising results, because they seem to be mixtures of pigments. One grey strip in a Gymnocalycium flower gave an amazing brilliant red fluorescence.
Spines seem to fluoresce brilliantly, as do the "spots" on some Haworthia.
All new territory for me .... but exciting nonetheless
