Gomphocarpus fruticosus (swan plant; narrow-leaved cotton bush) is a species of plant native to South Africa. ^[2] It is also common in Australia and New Zealand where it is a host of the monarch butterfly. ^[3] The plant's tissues contain sufficient cardenolides that consumption of significant quantities of the plant's leaves, stems, or fruit may lead to death in livestock and humans. ^{[4] [5] [6]}
