Gardening-Holly Sex

In this Dec. 11, 2013 photo, holly, would be fruit-less without the help of a nearby male plant, in New Paltz, New York. Unlike many plants, holly’s pollen is borne on flowers that are strictly male, while its eggs are contained in flowers that are strictly female. So you need trees of both sexes if you want to see any berries. (AP Photo/Lee Reich)
