Mike, I know DF has more petals and holds form longer. That's just from seeing it on exhibition tables. I know nothing at all about DF's growth habit. If it is as robust as Conundrum's, it would be an excellent choice.

I would take DF anytime. She is a healthy hardy bloom machine here and laughs at our winters. I got her and Arcanum at the same time from Rosemania. I really like both of them but have fallen hopelessly in love with Arcanum....

I would have to say DF too. Conundrum opens too fast. Ohh, I love arcanum! Mine has not been happy lately. I need to check the pH.

This info is nice to know, I just got Dancing Flame for other reasons.

Interesting. Before I starting thinking about Dancing Flame, I was considering Arcanum, but several people posted complaining that it didn't grow well for them. I grow everything in pots. I wonder if that would make a difference.
I wish Rosemania would sell Dancing Flame. That seems to be Tucker's place. I wonder why they don't offer that one.

Mike in New Orleans,
After 2 or 3 growing seasons, I finally shovel pruned my Arcanum because it wasn't growing well.

I planted Conundrum in April. The sencond saturday in June
I won Queen with Conundrum. It does only have about 20 petals. It must be cot 1/2 open to show it.
I am going to get Dancing Flame this year.

Dancing Flame is better overall.
