Title: Male and female possumhaws for berries from Georgetown TX
Answered by: Barbara Medford

QUESTION:

Do I need to plant two ilex decidua (possumhaws), a male and female to have red berries on the tree in the winter?

ANSWER:

Yes, the problem is going to be determining which is which. If you go to a nursery and the Ilex decidua (Possumhaw) all have berries, they are all females. Very often, nursery plants are propagated by cloning, which means every offspring will be the same sex. If you go to the nursery in Spring, the possumhaw will all have flowers, but that still doesn't tell you anything, they could be either sex. We are told that very skilled botanists with magnifying glasses can identify sex from examination of the flowers, but we aren't of that category.

If you ask for one male and one female at the nursery, they may have them but they may not know what you are talking about. When you see the possumhaws with berries, they may have been pollinated by male shrubs before the females ever left the greenhouse where they were propagated.

Here is a previous Mr. Smarty Plants article on this subject. The rule is that there must be a male of the same species and blooming at the same time somewhere close enough for the bees to pollinate.
