They are produced when the water in the soil is not frozen but the air temperature is. As water in the soil is drawn up through a plant’s stem, the water freezes and expands, breaking the stem walls and creating a flow of ice. As crack after crack yields another layer of ice, the total effect resembles the many layers of a flower petal. Each layer of ice is so thin, the frost flower is almost weightless and will shatter if touched.
THANK YOU so much for solving this mystery for me and my daughter. We were hiking in the Pacific coast rainforest of British Columbia one morning, and came upon a bunch of these. We didn't know what they were!
