Golden Dawn, the bush, sported many times, but most appear to be similar. The question arises whether these subsequent roses were distinct sports or re-namings, of existing sports in other countries. These sports were:
1934 Queensland Beauty, Australia.
1935 …a pure pink sport was seen at the nursery of D. Prior, but is is not so large a flower. Ref. ARA 1936 p53.
1937 Mrs. Violet Ewen, New Zealand.
1938 Apricot Dawn, America
1938 Pink Golden Dawn, America
1938 Exquisite, Sydney, Australia.
1939 Dorothy James, America.
1939 East Anglia, England.
1947 Mrs. Breedlove, America.
1957 Pink Flamingo, America.

The NRS classified 'Golden Dawn' as a Tea during its trials.
