Mauka crossing 2021?

It is hard to sync up mauka blanco and mauka rojo. They like to flower at different times, but I managed to get them going together for the first time in several years. I have come to believe that rojo (pink flowers) is self-sterile. It rarely sets seed. On the other hand, blanco sets abundant seed without a pollinator. I hope to be able to get a few crosses in both directions this year.
