Acacia Australia n early advocate for Wattle as the Australian national flower was Archibald James Campbell. On 8 September 1908 Campbell delivered a lecture to the Melbourne Photographers’ Club titled ‘Wattle Time; or Yellow-haired September’ in which he stated that ‘by numbers, the Wattle is almost exclusively Australian, and should undoubtedly be our National Flower’ (see Boden 1985). A published version of this lecture appeared in Campbell’s 1921 book ‘Golden Wattle: our national floral emblem’ where on page 16 he shows a photograph of A. pycnantha labelled ‘Australia’s National Flower’. However, the call for A. pycnantha as the national flower was not unanimous because there had been debate about whether Wattle or Waratah (Telopea speciosissima) should assume this honour. It was R.T. Baker who advocated the choice of the Warratah (which is now the floral emblem of New South Wales) (see Sowden 1913, Boden 1985 and Hitchcock 1991 for further details).
