Q. Who is Mr. Smarty Plants?

Title: No Berries on Possumhaw from Victoria, TX
Answered by: Mike Tomme

QUESTION:

I bought a Possumhaw about 4 years ago because I love red berry plants. So you can realize my disappointment in this very healthy looking green tree that refuses to give me any red berries. What is wrong with this baby of mine? I'll do anything to get some of those lovely red berries I see in pictures and other people's yards. Thanks.

ANSWER:

Congratulations, it's a boy!

Ilex decidua (Possumhaw) is a dioecious plant, meaning the flowers on an individual tree are either male or female. Since your "baby" is four years old and otherwise healthy, the most likely explanation for the lack of berries is that it is a male. A much less likely explanation is that it is a female, but there are no male trees in the vicinity. Here is a previous Mr. Smarty Plants anwer that discusses how near a male tree needs to be. The short answer is the pollination is done by bees and the male tree can be miles away.

The only way you can be sure you are purchasing a female possumhaw is to purchase it during the fall or winter and make sure it has berries.

I'm sure this isn't the answer you wanted to hear, but a male possumhaw is still a nice looking small tree that should do well in your landscape. Maybe you can hang christmas ornaments on it?
