Good to know on the 'Pluchea odorata' as it grows around here in brackish wetland areas.
"Sweet-scented camphorweed is a native plant found in saline and brackish marshes in New England. This species is one of few plants that exhibit "crystallofolia" (frost flowers or ribbons), unusual feathery or ribbon-like ice formations that sometimes appear on a plant during frost events, due to water being emitted along the stem or near the base of the dormant plant during freezing."
