Queensland Native Seeds

Cassinia laevis

Scientific NameCassinia laevis
Common Name(s)Cough Bush, Curry Bush, Rosemary Bush, Wild Rosemary


"Shrub to 3 m high; stems white-woolly usually with prominent scars from leaf bases." (PlantNet)


Cassinia laevis will attempt to flower almost every season however efficient seed collection requires better moisture through to ripening time when entire inflorescences may be cut. As fruit matures, structures containing the seed will begin to release and move away on air currents. The seed can be seen as part of a minute structure called an achene which is connected by a beak to a parachute like structure known as the pappas. These entire structures we call the, "seed units". They are extremely small, light and are best viewed with magnification. Fruiting material must be carefully cut as it ripens and dried in a reasonably draught proof enclosure. The dried material containing broken parts of inflorescences and high numbers of viable seeds per gram must be carefully processed down to a flowable state. The production of purified seed here is inefficient and unnecessary. This material will have high seed analysis and will freely blend with other commonly used native seeds when carrying out rehabilitation works.

Historical Notes


Some occurences in northern Queensland however more common in central to southern Queensland extending inland to Blackall. Also New South Wales and south-east South Australia. Some small occurences in the north-east of South Australia and around Alice Springs.
