It's definitely Iwan AB 'Golden Elf', and susie, the problem I have is that I never had temperatures close to even temperature (I live on a tropical island!), so I guess the heat really causes the flowers to not do as well as expected.
Wow, hotter than south Florida in summer! I don't envy you! We have about 10 months/ year in the 80's, 1 month in the 90's and 1 month (cool) 70's with rare 40's at night. The plants are used to the heat, but will drop buds when I bring them in the airconditioning!
