What is Ptilotus exaltatus?

Growing Ptilotus exaltatus in Australia

Ptilotus exaltatus is more commonly known as Mulla Mulla or Pink Mulla Mulla. They are famous for their beautiful conical spikes of feathery flowers, which look spectacular as cuttings in flower arrangements. 

A native Australian plant that grows well in warm temperate, semi-arid and arid climates. They are a perennial herb, with a short life cycle so are often grown as annuals. 

It is a small shrub, growing to less than a metre high, with thick blue-green leaves. The Ptilotus exaltatus flowers are typically pink or purple in colour. The striking flower spikes are about 10 cm in size, with dense pointed petals.

If you plan on growing mulla mulla from seed the best time to sow the seeds is in November. They then grow rapidly and flower from mid-autumn. Ptilotus exaltatus can be grown all year round but sowing seeds in warmer months is less ideal. 

Where to Position Mulla Mulla?

Ptilotus exaltatus should be positioned in a warm, sunny part of the garden. A sunny location is an essential ingredient of success when growing Ptilotus exaltatus. They should be getting at least around 8 hours of sunlight a day. 

Mulla mulla is best potted or planted in hot, dry areas of the garden, with excellent water drainage. Rockeries or container pots getting full sun are ideal and they can look spectacular as a complement to other natives or annuals.

Given the drought resistant nature of these Australian natives, they are ideal plants for putting in pots on a north facing patio or balcony, where other plants might suffer. Position in the middle or back of a garden display or pot, as the upright flower will contrast beautifully with those plants at the front.

  1. When Mulla Mulla is growing wild, the seeds are blown away to land where they will.

    They grow with very little rainfall If I simulate this in my frontage will they grow

    Thanks

  2. Hi Lorraine,

    It depends on where you live and what the ground is like there. In theory, yes, broadcast sowing mulla mulla will work, but you’ll have to do it at the right time of year, and prepare the ground I advance. They don’t germinate well with competition, so clear the area you’re planting first if possible.

    They need free-draining, sandy, soil if you’ve got it. If you’ve got moisture retentive loamy soil in the garden, either dig a load of sand through, or use the same method in pots. Or, just grow them on first in containers and plant into the ground by improvising just that section of soil first.

    Good luck with it and let us know how you get on!
