Frost Flowers


Frost flowers is the name commonly given to a condition in which thin layers of ice are extruded from long-stemmed plants in autumn or early winter. The thin layers of ice are often formed into exquisite patterns that curl into "petals" that resemble flowers.


The formation of frost flowers, also known as "ice flowers," is apparently dependent on a freezing weather condition occurring when the ground is not already frozen. The sap in the stem of the plants will expand (water expands when frozen), causing long, thin cracks to form along the length of the stem. Water is then drawn through these cracks via capillary action and freezes upon contact with the air. As more water is drawn through the cracks it pushes the thin ice layers further from the stem, causing a thin "petal" to form. In the case of woody plants and tree branches the freezing water is squeezed through the pores of the plant forming long thin strings of ice that look uncannily like hair ie: "frost beard".


The petals of frost flowers are very delicate and will break when touched. They usually melt or sublimate when exposed to sunlight and are usually visible in the early morning or in shaded areas. **You can click the images for a closer view.**

Frost flowers are beautiful. After living 10 years in NJ and 7 years in MI, I have never seen these. Wow. I've missed out.

I know these don't exist in So. Cal or Seattle.........

Harlekwin said...

My goodness, those almost don't look real! I've never heard of this before (yeah, I know, that's what everyone else has said). Is this something that only happens in certain areas or certain types of plants?

Cool, here's my something learned today!

Thanks for your visit today!

Lizza said...

Oh my, those are certainly pretty. One of nature's lovely gifts. Thanks for sharing the info and the pics.

Travis said...

I've never heard of that. It kind of looks like feathers. Neat!

Happy MM!

Marilyn said...

That is so cool... and you did a great job of explaining how it happens. I wonder how I got through two botony classes without every hearing about those. Maybe if I got outside before the sun came up once in a while, I'd have seen one.

Imma (Alice) at I Was Born2Cree8 said...

Like many others, I have never seen or heard about this before. It's a very interesting post and perfect for the theme. Thanks for sharing this, I know many of us learned something new here today.
