“ One of the best known is the Australian species H. bracteatum, with several varieties, including double forms, of different colours; H. vestitum (Cape of Good Hope) has white satiny heads. Others are species of Helipterum (West Australia and South Africa) , Ammobium and Waitzia (Australia) and Xeranthemum (south Europe) . Several members of the natural order Amarantaceae have also “everlasting” flowers; such are Gomphrena globosa, with rounded or oval heads of white, orange, rose or violet, scarious bracts, and Celosia pyramidalis, with its elegant, loose, pyramidal inflorescences. ”
