Lysimachia ephemerum in Ultra-Violet fluorescence

This plant, with common names of ‘willow-leaved loosestrife’ or ‘milky loosestrife’ is one of the plants my wife grows in our garden. I decided to try photographing it using ultra-violet (UV) fluorescence. Here are some of the results using the ‘before/after’ sliders (drag the slider or dividing line from side to side)

First I show the daylight and UV fluorescence pair:

Lysimachia ephemerum in daylight flash
Lysimachia ephemerum in UV Fluorescence

Having the sliders is OK on a website but how do you show both in the one image. Here I have tried a diagonal divider line splitting the image into 2 halves. I show 2 versions here:

Split one way with a diagonal line
Split another way with a diagonal line

I then tried different blending modes (methods to overlay images) to see what happens:

Luminosity blending
Vivid blending

An interesting exercise but I am not sure where this takes me at the moment!
