Asking club judges to help can be very useful. Do you have a specific project in mind.? With my SDBs I have been trying to get a true red amoena. You will note the photo of my Reddy Set, which is on all my posts, that the red does not entirely cover the falls. A friend from Neb. (now deceased) was trying the same thing & we exchanged seedlings. No luck.
Not everyone agreed with us. When Paul Black first saw RS as a seedling he complimented the nice white edge. When I told him that I was trying to remove the white edge, he looked at me like I had 2 heads.
