I have the following flowering:
Y. fila x rostrata (2)
Y. flaccida x 'reverchonii-thompsoniana' (2)
Y. flaccida 'Tenn'
Y. flaccida 'Tenn big bloom'
Y. fila x constricta (4)
Y. flaccida 'Poconos Mts, PA' x filata
Y. filamentosa 'Tenn'
Y. gloriosa 'Tenn'
Y. flaccida x gloriosa #2105 'Benny Jensen hybrid'
Y. flaccida variegata
I've been doing well pollenating different Yuccas but it's always a battle against the beetles which kill off the flowers. I spray the blooms with insecticide every other day which really helps but kills the Yucca moths too. I'll know more in another week, especially after tonight when the hurricane is suppose to clip us with wind.
