Yes, if you live in its native range (southeastern and central US) and have partial shade and moist soil. It is grown for its unique winter interest.
The ice is made from water exuded from the plant's own stem tissues when they freeze and split. It's a physiological process, not just frost settling on it.
They are different genera. Frostweed typically refers to Verbesina virginica, while frostwort usually refers to species in the genus Helianthemum, though both share the ice-exuding trait.
