Hosta coerulea, known also as Funkia or "plantain lily".

The light color gives me a comforting and relaxing atmosphere. Nice shot.

I have something similar:

Yeah, these flowers are quite similar. Very nice photo of Amaryllis. Smile

The "blue to pinkish purple" color transition in starflower is fascinating. Nice photos.

Species like the Polygonia c-album butterfly can also be seen here in HK.

Yeah, with white dots on the very end which give an impression of small flashlights. Wink

Calendula officinalis, commonly called in English "pot marigold".

Image


Tagetes patula, known by the English name "French marigold", variety "Tiger Eyes".

Image


Both photos were taken shortly after the morning rain. The flower petals of the French marigold specimen are evenly covered with water whereas petals of the pot marigold specimen show almost ideally half-spherical drops separated each from the other. The difference may suggest that structure and / or chemical composition of the flower petals in the case of French marigold ("Tiger Eyes") lowers surface tension whereas pot marigold petals seem to hydrophobic.

I believe its two antennas support wireless ac dual band standard! Nice close-up photos.

It looks like the petals of the Tiger Eyes flower are waxed. Amazing photo.

You can make a simple experiment to show how different water drops behave on the hydrophilic and hydrophobic surfaces. The main
cause of these differences is change in surface tension when water contacts with various materials.

Take a sheet of fine-grained sandpaper and cut out two pieces. One of them cover with paraffin wax or stearin (just take a piece of candle and rub it in that piece of sandpaper). After that take a dropper or a syringe filled with pure water and place a few drops of water on the piece of "raw" sandpaper and the piece of "waxed" sandpaper. Observe the noticeable difference and dynamics of changes. On the piece of "waxed" sandpaper drops resemble a kind of ellipsoids flattened on the underside with easily noticeable contact surface between two materials whereas drops on the piece of "raw" sandpaper behave differently, spilling freely over its surface due to lowered surface tension.
