The plant below is (Philo. "Chumley curly" x (P. speciosum x P. bipinnatifidum)), F2 generation. I was trying to get the Chumley curly to drop back out by going for the F2 - the results are certainly unique and interesting but not yet the Chumley curly. I've since done a successful F3 (selfing the F2) and should have a better chance of getting the Chumley curly to drop back out. The seedlings are still too small to see if I got it yet.
By "drop back out", I mean that a plant or plants with the characteristics of one of the original parents appears in the seedlings. This is done typically by selfing the F1 to get the F2, or selfing the F2 to get the F3. In some cases, it may require going to the F4 to get the segregation. In this way I can recover a parent, which in this case is the P. "Chumley curly".
