Answer: As a matter of fact, insects transfer the pollen from the male flowers to the female flowers so if you plant your hollies within 100 feet of one another, the insects will be most accommodating. I've found in my own garden that hollies can be planted farther apart and as long as they're within sight of one another, the female produces berries. Bees just seem to know how and when to visit the flowers and will go directly from one shrub to the other on a single outing, transferring pollen as they go. Enjoy your hollies!
