Cassinia quinquefaria, commonly known as Cough Bush or Dusty Miller, is a deciduous shrub native to a variety of habitats including grasslands, open woodlands, and forest margins in eastern Australia and Victoria. It typically grows to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) and is characterized by its narrow, linear leaves that are covered with glandular hairs, giving them a sticky texture. The foliage often has a silvery appearance due to the dense covering of hairs. Creamy-white flowers are borne in dense panicles and bloom mainly in summer and autumn, providing a showy display that can attract pollinators.

Cassinia quinquefaria is valued for its drought tolerance and ability to thrive in a range of soil types, making it a versatile choice for low-maintenance gardens, native plantings, and restoration projects. It is also used as a filler in mixed borders and can be pruned to form a dense hedge. This shrub prefers full sun to part shade and requires minimal water once established, making it suitable for xeriscaping. It is adaptable to soils with medium drainage but can tolerate periods of dryness.CC BY-SA 4.0
