Answer: This should work as long as they are planted nearby. You would want to stick with the same female as is in the combination you already have -- China Girl. If you want to use Blue Girl as the extra female plants then you would want to plant a Blue Boy or a Berri-Magic Kids as the pollen source. The reason for this is the male holly must bloom at the same time as the female in order for fruit set to occur, that is why they are named in pairs. Enjoy your hollies!
