Frost Flowers — and a Few Wild Ones

Crystalline flowers flow across the storm windows in our north-facing bathroom.  In this subzero weather, the moisture from our steamy morning showers seeps through the old, loose-fitting decorative windows and condenses as frost on the cold glass panes that cover the screens.  The patterns that take shape depend on the amount of dirt, scratches and residue on the glass, and the humidity level and temperature of the air.  These patterns are often called frost flowers, roses or ferns.

According to Halldor Svavarsson at the Icelandic Web of Science the most commonly formed pattern of crystallization is hexagonal because it requires the least amount of energy.  If the moisture settles and freezes quickly, the roses will be small and close together.  If not, the roses may be fewer in number, larger in size and may spread out on the glass.

Frost roses and ferns are delicate and lovely, but I prefer nature’s wildflowers.  Here are a few from last summer:

Monarda fistulosa also known as bergamot and beebalm.

Fragrant, spicy wild bergamot or bee balm (Monarda fistulosa).

Vernonia fasciculata also know as smooth ironweed and prairie ironweed.

Prairie or smooth ironweed (Vernonia fasciculata).

New England aster also known as Michaelmas Daisy (Symphyotrichum novae-angliae).

New England aster or Michaelmas Daisy (Symphyotrichum novae-angliae).

Fringed loosestrife (Lysimachia ciliata) a native perennial that is unrelated to the non-native, invasive purple loosestrife.

  1. Isn’t it cool that the frost flowers allow their delicate beauty to speak to the longing in all of us for winter to end soon!!! I love to see your incredible photography and catch a glimpse of the many things I would otherwise miss. Thank you for lending me your eyes! You are bringing beauty back into my days when I need it most. Getting to work in the dark and leaving in the dark is no fun.
    THANK YOU!

  2. Just beautiful, Beth. Last weekend I introduced 3.5 year old Lukas to the delicate tracery that Jack Frost left on our windows. Thank You!

  3. Beautiful Beth. I love your explanations too. “It depends on how much dirt and scratches.” The poetry of the picture. The pragmatism of the explanation. So how much dirt is there? 🙂
