Hi Carebear,
I have many responses to your messages above, but at the moment I am planting some of my Razzle Dazzle seeds in-ground, and a rain front is approaching (slowly) from the West, so I will defer a detailed response until the rain arrives. I want to get as many seeds in the ground as I can before the rain arrives. Incidentally, Eden Brother's Swirls are approximately equivalent to Whirligig.
The Whirligigs themselves vary significantly, depending on which seed grower they come from. A field of zinnias becomes somewhat unique, and different fields of zinnias can produce somewhat different results, even though their seed packets have the same variety name. More on that later. Those Razzle Dazzles are calling to me.
