Hi Shawn,
The "Cresto Series" is a new variety of zinnias that is supposed to address the problem that we have been seeing with the Zinderellas. In order to see more info on the Cresto zinnias, scroll down all the way to the bottom of this "New Varieties" page at the GeoSeed website.

Unfortunately, White is not a color that is offered, but I suppose I will just order the "Mix" and see what I get. Notice that the Cresto zinnias do not claim 100% on-type results. Incidentally, GeoSeeds do not have an online store. You have to mail-order with them, or possibly order over the phone.
