Karen, that thread answered all my questions about summersowing and MORE! I read the whole thing. Thank you so much. And the dates of the 2009 thread you cited above start in July, just like now. And Trudi's list of appropriate seeds from her Wintersown.org (cited in the last entry of the thread) expanded on more seeds to SS, too. I'm excited to start some zinnias and see what happens. Not to mention some other summer blooming annuals to fill in for my pansies that are just about over.
(Excuse me while I go rummage in my leftover seed boxes. . . Oh my goodness; I need JUGS!)
