Flower ID appreciated, and a question

My previous post on this topic didn't seem to make it. Here is the flower again, and also a question.

Has anyone here used an iPhone app to identify flowers? For my purposes, this would be a terrific asset.

Thanks again for your help,
David

 

Zinnia, one of the single-blooming cultivars.

 

Looks like Helenium. There are several named cultivars that it might be.

My first thought was zinnia, too, but it didn't look quite like any zinnia I'd seen before. Helenium seems a better match. Thanks!

 

Definitely looks like Helenium. Helenium Rotkäppchen?
Try to contact http://www.helenium.net/ , may be they will narrow it down for you to the species or cultivar.
By the way, it never hurts to post a picture of the whole plant and/or leaves, along with flowers.
