Discussion Also known as: oldwoman, beach wormwood, beach sagewort. This plant is now well established along the Atlantic Coast, where it is a common, solitary plant on secondary dunes. This plant survives the heat and effects of salt spray partly through its woolly leaves: the dense coating of white hairs not only reflects sunlight, but also provides good insulation.
