Common name: Tall Mulla Mulla
Origin of Scientific Name
Ptilotus – (Greek) ptilotos – winged, particularly soft-winged, whether membranous or feathered.
exaltatus – (Latin) raised up, tall, referring to the flower spikes.
Ptilotus exaltatus, an erect annual herb, is one of the largest of the Mulla Mullas. It is widespread throughout the arid and semi-arid regions of Australia including Western Australia, where it occurs in all areas except the Nullarbor Plain above a line drawn from Perth to Esperance.
The Tall Mulla Mulla grows to 1.2 metres with leathery green foliage. Highly attractive purple flowers in dense, conical heads up to ten cm in size appear from April to November in its natural habitat.
A cultivar of this species is produced commercially as Ptilotus exaltatus ‘Joey’ and looks amazing as a container plant or complements other natives in a larger garden bed.
- Propagate from seed, without any pre-treatment.
- Seed best sown in November and grown as a summer annual.
- Established plants require an open position in full sun with excellent drainage.
