Smallhead doll's daisy (Boltonia diffusa) when exposed to ...

The image presents a comparative view of Smallhead doll's daisy flowers under two different lighting conditions: regular daylight and ultraviolet (UV-A) blacklight illumination.

**Image Layout**

The image is divided into two halves by a horizontal line. The top half displays the flowers in normal daylight, while the bottom half shows them illuminated by a 365 nm UV-A blacklight.

**Flower Details**

Each flower consists of:

* A yellow center
* White petals

The petals are slightly curved and have an irregular shape with pointed tips.

**Lighting Conditions**

In the top half of the image, the flowers appear as they would in natural daylight. The colors are muted, and the details of the petals are not particularly prominent.

In contrast, when illuminated by a 365 nm UV-A blacklight (bottom half), the flowers exhibit an intense blue glow. This is likely due to the presence of fluorescent pigments in the petals that absorb light at this specific wavelength and emit it back as visible blue light.

**Background**

The background of both images appears to be a dark surface, possibly a table or countertop. The exact color of the background is not clear, but it seems to be a neutral shade that does not significantly affect the appearance of the flowers.

**Overall**

The image effectively demonstrates the effect of different lighting conditions on the appearance of Smallhead doll's daisy flowers. The use of UV-A blacklight highlights the unique properties of these plants and provides a fascinating glimpse into their biology. – AI vision
