Chris,
I don't know about Burnt Saffron yet. I have a few 8 inch pots of it growing for evaluation but they are among many others at the moment. When they start blooming I will spot them again and take a good look. Yes, Blue Denim is 08-0136. A similar one is 08-0131 but it does not set seed so is not given much attention yet.

It would be interesting to see if Bunt Saffron is a better grower than Black dragon. I was thinking about another interesting cross to do between Black dragon and Dragon's heart. They are both offspring of Dragons Breath, which have a very dark color. It would be interesting to see if their offspring are dark as well because most likely their dark gene is from the same source, Dragons breath.
It is a good thing that Blue Denium sets seed because I am sure we will be seeing some of its offspring in the next few years. It might be interesting to see if it is crossed with gator pride the offspring would look something like when GP was crossed with blue ballerina. Perhaps you could get a totally solid blue flower from that cross! At anyrate I am pretty excited for the possibilities of that cv.
