Rime frost built up on a twig and a milkweed seed pod.
Unlike Hoar frost, which forms from water vapor in the air, Rime frost forms when a light breeze moves the small water droplets in a fog or mist over a cold surface.
Even though it looks like the breeze was coming from the left side, in these pictures, rime frost grows on the windward side - the right side of this twig and seed pod!
