Synonyms: Helipterum
Family: Asteraceae
Common Name: Everlasting or Paper Daisy

This group of annual or perennial plants was formerly classified with Heliptennn. Those species transferred to the genus Rhodanthe are Australian. These plants are grown massed for garden display and for the papery flower heads which can be dried and kept for long periods.

Species

R. anthemoides is a perennial, occur-ring in most Australian states, often in alpine areas. It grows around 50 cm (20 in) high and bears white, paper daisies in summer.

R. floribunda, a white summer-flowering annual, occurs naturally in New South Wales, South Australia, Western Australia and the Northern Territory.

R. manglesii, from Western Australia, has white or pink, paper daisy flowers in summer. This free-flowering annual is frequently grown as a bedding plant, producing a spectacular and long-lasting display. It grows about 30 cm (12 in) high.

R. chlorocephala subsp. rosea, also known as Acroclineum roseunr and Helipterum roseunr, is another popular, summer-flowering annual with papery flowers in pink, white or almost red. Both R. chlorocephala subsp. rosea and R. manglesii are grown for the cut flower trade.

Cultivation

Grow as annuals, raising plants from seed. In frost-prone climates, sow under glass in early spring. Germinate at 15°C (59°F). Plant out when frosts are over. Where frosts are not a problem, sow in flowering positions in mid-spring. Plants prefer a very well drained, poorish soil and a position in full sun. If you want to cut the flowers for drying, do so before they have opened completely. Bunches can be hung upside down in a dry, airy place to continue drying.

Climate

Zone 9. Best in areas with low humidity and hot, dry summer weather.
