What do you think Dave ? Should the common name be Coneflower Sundown. Or should Sundown be the synonym? And do synonyms show up on the first page when looking up plant? I would think most people would be looking for the name Sundown . It is usually sold by that name.
Lynn the picture was already there when I started working on the Echinacea. I think it is a Sundown , I remember reading that the Big Sky series had problems with petal development, If you feel it is something different please let me know. Also if you get a chance look at 2 pictures under Ozark Coneflower( Echinacea Paradoxa) they look white and do not look like any Paradoxa I have seen. What do you think?
