Additional Notes

Comments

The common name frostweed comes from the plant's behavior when there is a hard frost. The stem splits near the base and the sap that seeps out freezes in conspicuous ribbons of ice. Helianthemum bicknellii is another Kansas plant that goes by the common name "frostweed".
