A small spring flower native to Continental Europe and the British Isles, H. non-scripta only occurs naturalised in the Nordic countries. In Norway most observations are in coastal regions. It occurs in mass proliferation in deciduous forests before the onset of leafing in spring. The flowers are fragrant and attract a lot of pollinators. The corolla is pale blue to pinkish blue.

 

Plants collected and photographed at Bømlo, Western Norway 13 May 2007. These specimens were fully naturalised in open coastal grasslands.

Ultraviolet light: Nikon D200, UV-Nikkor 105 mm f/4.5 lens, Baader U2" (Venus) filter, SB-140 flash

 

Apparently the UV rendition is a near 'reversal' of visible-light appearance. This is not commonly seen with UV signatures.

Ultraviolet induced fluorescence (UVIFL): Nikon D200, UV-Nikkor 105 mm f/4.5 lens, Baader UV/IR Cut filter + Kodak 2E filter, Nichia UV-LED (peak 365 nm)

 

Interestingly, for H. non-scripta it is the anthers that fluoresce not the pollen itself.
