Wild buckwheat (Eriogonum) when exposed to ...

The image presents a comparative view of wild buckwheat (Eriogonum) flowers under two different lighting conditions: regular daylight and ultraviolet (UV-A) illumination from a blacklight.

**Daylight View**

* The top half of the image showcases the flowers in their natural state, bathed in sunlight.
* The flowers appear as small, delicate white blooms with five petals each, arranged on slender stems.
* The background is dark, providing contrast to the light-colored flowers and stems.

**UV-A Illumination View**

* The bottom half of the image reveals the same flowers when exposed to UV-A radiation from a blacklight.
* Under this specialized lighting, the flowers exhibit a distinct fluorescence effect, with their petals glowing in shades of blue and green.
* This phenomenon is likely due to the presence of fluorescent pigments or chemicals within the plant's cells that absorb UV light and emit longer wavelengths.

**Comparison**

* The juxtaposition of these two images highlights the unique properties of wild buckwheat flowers when exposed to different types of illumination.
* While they appear relatively unchanged in daylight, their response to UV-A radiation is striking, revealing a hidden aspect of their biology. – AI vision
