Window frost (also called fern frost or ice flowers) forms when a glass pane is exposed to very cold air on the outside and warmer, moderately moist air on the inside. If the pane is a bad insulator (for example, if it is a single-pane window), water vapour condenses on the glass, forming frost patterns.
The leaves are up to 18 centimetres (7.1 in) long and 5.1 centimetres (2 in) wide and slightly toothed. Flower heads consist of multiple flowers arranged in a cluster, or corymb, at the terminal end of the stems. [4] Each flower head actually consists of 1 to 5 ray florets and 8 to 15 disk florets.
