NY210 - In search of the Australian petunia

A list of Australian native species with potential for use as bedding plants was developed in 1992-93 after an industry evaluation and germination experiments. Annual species with the greatest immediate potential were Actinotus leusccoephalus, Brunoia australis, Calandrinia polyandra, Gomphrena canescans, Velleia rosea, V.trinervis and the Lobelia species. The effect of incubation temperature and the plant growth hormones, gibberellic acid and benzylaminopurine, used either alone or in combination, was also assessed.
