[UV] Mirabilis jalapa UV ultraviolet fluorescence - from "Kingdom of Plants"

Today about some earlier work I have done on Mirabilis jalapa flowers, that have some very special abilities - their pollens and flower petals are fluorescent when seen under ultraviolet light. This may also bee seen in the forthcoming new series about Kew Gardens by Sir David Attenborough called "Kingdom of Plant s 3D".

UV induced visible fluorescence:


Mirabilis' pollen emits a strong blue greenish fluorescent light and some scientists believe that the special night active moths that pollinate them, might be able to see this.

Stay tuned, more will follow on that fascinating subject...

[UV] Spring Anemone Flowers in Reflected Ultraviolet UV Light

Today about yellow and pink Anemones in reflected ultraviolet light. Also these were shot using my Steinheil Quarzobjektiv f1.8 / 5cm (50mm) originating from the Steinheil Museum, which I have published earlier about.

I was able to record "UV yellow" Anemone flowers, reflecting UV around 360nm, which funny enough are also deep yellow in visible light.



Here more shots about those special pink Anemones, which have in UV a reverse pattern than in visible light!






Stay tuned, more will follow on that fascinating subject...
