Have you ever wanted a plant really bad and then were left feeling let down once you bought said plant for your garden? Echinacea purpurea 'Double Decker' also sold under 'Doppleganger' is a garden 'mutant' first discovered by German plant breeder Eugen Schleipfer. It is said that he found an unusal Purple Coneflower and spent many years selecting for the unusual flower we have now.
I purchased mine two years ago at a local Home Depot garden center and that should have been a big enough red flag. The Home Depot is good for a lot of things but specialty plants for the garden, IMO, is not one of them. After having seen many beautiful photos of the 'Double Decker' flower on the internet and plant catalogs I was eager to add this weird plant to my garden and when I found them for $5.00 I couldn't pass them up.
