On autumn or early winter mornings, it is possible – though extremely rare – to see beautiful ribbons of ice crystals on the lower stems of some plants. These ice sculptures are called “Frost Flowers”. They disappear quickly on the day they occur, melting like frost when the air warms or rays of sunlight fall on the delicate structures. Even some of the most experienced nature explorers have never seen frost flowers. You just have to be in the right place at the right time.

How do they form?

When first hard freeze occurs, plants’ stems are ruptured. A frost flower is created when warm plant sap in extremely thin layers is pushed out from the stems of plants or occasionally wood, and freezes on contact with the cold air.

Frost flowers have a lot of other names. They can be called frost castles, ice castles, ice blossoms, or even crystallofolia, the scientific name.
