Halberd-leaf rosemallow (Hibiscus laevis)

The halberd-leaf rosemallow (Hibiscus laevis) produces striking, delicate flowers. These blossoms only open in bright sunlight and typically last for just one day. This deciduous perennial shares a connection with the marshmallow plant, which was historically used in making early marshmallow treats. The plant's name comes from the resemblance of its leaves to the halberd, a medieval weapon.
