Photo #4 in my series on frost flowers.
Frost flowers are formed when water inside a plant escapes through a split in the plant's skin, and meets very cold air. The water freezes quickly, but more water continues flowing, thus pushing the ice further out from the plant.

Hi William,

Most interesting post.
I spotted frost flowers only one time in my life. I guess France is not cold enough so that we can spot this easily over here. I posted this in that time:

I had no idea this phenomenon has a name. I know it now thanks to your posting. Now that I know the name, I found some more beautiful ones on the net. I'm so greatful to you.
Hard to say which of your 4 posts is the best.
I see a slight motion blur in your pics. 1/60 might be slow depending on the focal length you use. In the photo info view I do not understand this:
Focal Length 9500/1000 mm
if 1000mm or more were used, 1/60 is definately inappropriate.
I see you have Photoshop. I recommend you increase the contrast. In case like this (where details in whites are important) "curve" should give even beter result than "contrast".
Small nits in great pics anyway.
