| Abstract:
Australia’s major production seasons for cut flowers derived from the native flora are winter and spring, which coincide with summer and autumn in the important flower markets of the northern hemisphere. Relatively little product is available for the northern winter despite strong demand. This paper explores the potential of a species from northern Australia, Haemodorum coccineum (‘scarlet bloodroot’), as a summer flowering cut flower crop. Despite being very easy to propagate, growth of H. coccineum appears to require soil temperatures in excess of 22ºC at rhizome depth. This unique dormancy mechanism may limit production to tropical environments. | |
