Hi Matteo,
Thank you for your feedback and for this crossing. I do have the Riptide by myself and love it. I think it was a good idea to cross it with roal Wallenberg, so it got their powerful colors and the glowing from Riptide.
I already marked the #6 for staying. It don't have to increase the flower diameter as long as it keeps their strong colors.
Number #3 is still living as well. Just not at my balcony. It's now one floor below, at the terrace, in other hands.
#2 has still a question mark, but good chances with that colors. This one maybe should increase little bit the flower diameter without losing it's brightness. We will see.
Today I sorted out #5. But I will give it in other hands, maybe the same as its sister. It's really beautiful, but I already have very similar ones (Krakatoa or another crossing with Raoul Wallenberg) with bigger flowers. Just crossing it with one off its sister could be a reason to keep it, to go for F2 hybrods.
And there should be #1 and #4 somewhere. It seems they did not flower yet or got lost in between. Have to check...
