Comment

Leucochrysum albicans is endemic to Queensland, New South Wales, Victoria and Tasmania. The flower heads retain their colour when dried. The yellow bracts suggest that this specimen was subspecies albicans variety albicans. The plant was grown by a Central Victorian plant nursery from seed collected near Chewton, Victoria.
