Hibiscus grandiflorus and hybrid

I'm already collecting first pods off of the Hibiscus 'Blue River II' x grandiflorus F1 hybrid. So, I took this picture of those pods, with a shoot of Hibiscus grandiflorus itself to show you how grandiflorus hasn't even decided to flower yet. There might be some microscopic buds forming in that shoot tip, but we'll be lucky to see them open before a hard frost. See why I was so glad that the hybrid didn't inherit that grandiflorus photoperiod sensitivity.
