Ptilotus

Family: Amaranthaceae
Common Name: Mulla Mulla

There are around 100 species in this genus of perennials which are found in semi-arid regions of all states of Australia, except Tasmania. Pretty, greenish or pinkish brushes, sometimes lightly fragrant, dot the sandy deserts of inland Australia after rain. The soft, hairy foliage is grayish white in colour. Very attractive when mass planted, they are suitable for growing in rockeries and pebble gardens.

Cultivation

In frost-prone climates grow in an airy cool greenhouse or conservatory, in pots of soil-based potting compost. Ensure maximum light. Water very sparingly in winter, normally at other times. In the garden, grow in very well-drained soil with full sun. Propagate in spring from seed germinated at 16°C (61°F).
