It won't be a bleached E. paradoxa Bob, Echinacea paradoxa is a species, thus commands a lower case in the species epithet. Species don't vary a great deal, nor have strange shaped petals happening as you might find in a hybrid.
E. paradoxa has a very specific shape with narrow drooping petals and a large prominent cone, yellow is an unusual colour for Echinacea and isn't found in another straight Echinacea species that I know of.

Hybrids with drooping petals and/or yellow colouring are likely to be a cross between E. paradoxa and E. purpurea, as is the case with Echinacea 'Adam Saul'. Echinacea pallida is another with narrow drooping petals but is a bright pink.
