I just purchased 2 Jolly Red Winterberry bushes. I need a male polinator bush (Ilex x 'Apollo' is a possibility). What other male bushes would be good to fertilize the Jolly Red bushes? I need suggestions of Nurseries in NE PA and Upstate NY that would have them in stock. I am frustrated since the supplier that my source used to get the Jolly Red bushes does not even list male bushes in their catalogue. Is there such a thing as a self polinator? By my research, I would say no, but would like other's knowledge on this.
