Sorry for the OT post, but I need some feedback (off-list is fine) from people familiar with Genus Silphium. My Silphium brachiatum and S. perfoliatum seem to have hybridized in my garden. I'd like a second opinion! Please click the link. http://www.badbear.com/Silphium/silphium.html If this is the first such hybrid do I get to name it S. x krambii or anything like that? :-D Thanks, Dennis in Cincinnati
