Rabbit ice forms when the air hits freezing temperatures and sap in the stems of plants expands as it freezes, causing cracks to form along a stem. Water is then drawn out through the cracks, freezing as it hits the air, and forms layer after thin layer as more water is drawn out, eventually creating petals or ribbons of ice.

Your best chances of spotting rabbit frost is in the early mornings in wooded, shaded areas when weather conditions are just right.
