Zinnia cultivar?

I'd appreciate help identifying this Zinnia, as I'm using it and several variants to create a series of flower mandalas (works in progress are at http://www.facebook.com/flowermandalas). Thanks!

 

Yup, it's a Zinnia elegans, but it's impossible to find out the exact cv. name... :(

 

Thanks for the response. It was, anyway, worth a try asking here. This board has been so helpful, over the years.
