I've saved 5 of theses (2019) as reselects and breeders. Seedlings 1 & 5 are white, while 2, 3 & 4 are all bitone blue. Of course, the best branching has the most taylored flowers. Murphy's iris law!
2019-04 is my favorite at this point, but it seems I failed to get a photo.
Here are 2019-01, 2019-03, & 2019-05
