mystery flower with ants!

I can't remember the name of this unusual yellow flower with beautiful green foliage, but maybe my friend Ann Hall, who is a florida friendly garden expert will know. (Ann: it is one that Grant brought me when he came to do some landscaping). Whatever it is, I think it;'s magnificent, so I am tagging it for FlowerFriday. More power to flowers and many thanks to BikerBear for hosting even while traveling! 

Make sure to view large to see the teeny tiny ants.... oh I guess you can see them anyway!! 
p.s. One more blip has been added, if you work backwards ; o)
