Rhodanthe floribunda is a potential Australian native flower species. Studying the influences of chilling duration and seedling ages at chilling on flowering is important to develop a novel species for commercialization. The study was conducted in southern Queensland, Australia during 28 September 2009 to 1 March 2010. Seedlings of four age groups (1, 7, 14, 28 days old) were exposed to different cooling periods (0, 3, 7, 14 and 21 days) at 20/100C under short day (11h). It was found that R. floribunda has a facultative requirement for flowering in response to low temperature. The species could perceive vernalization at a very early stage, suggesting a short juvenile phase of this species. The longest chilling duration and the oldest seedlings prior to chilling had faster development rate and were more floriferous.
