Helipterum

Rhodanthe chlorocephala

Unique black-and-white color combination. Pierrot White provides a distinctive, moody look for both cut and dried florals, though the plant stature is a bit short for cutting. Productive plants produce relatively small, 1–2" upward-facing, daisy-like flowers with papery petals. The flowers have a long vase life and also make excellent dried flowers. Plants are branching basally, which makes the thin, wiry stems easy to cut and strip. Helipterum is also known as Acroclinium, immortelle, paper daisy, Australian everlasting, and everlasting daisy.
