I have not seen many Deserts or crosses in person but from what I have seen and what I see here I say you nailed it and you got the female to produce... Now if only we could know the secrets. Congrats they are all beautiful and you are extremely lucky to have them. If I was you I would hold each and every one back to try to get some more females that produce. Maybe you got one that will and by making a line from her you could possibly get more that do.
