A thank you again to Margaret Morgan of Sydney, Australia for sharing her photographs. If you didn't visit her web site when she previously submitted a photograph, here it is again: Margaret Morgan. Thanks, Margaret!
I'm away on a short vacation, so only the photograph and a couple links today. Margaret suggested this link about the species Telopea speciosissima: the Floral Emblem of New South Wales. Information about the cultivar can be found on the site of the Australian Cultivar Registration Authority: Telopea speciosissima 'Wirrimbirra White'.
