Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Identification of thorny shrub with blue berries
Answered by: Nan Hampton

QUESTION:

Thorny shrub with blue berries. In our acid sandy loam we have many thorn bushes. This one has small leaves like a wild pomegranate, long thorns. berries of the size and color of blueberries and is very invasive and hard to get rid of. What is this rascal?

ANSWER:

Mr. Smarty Plants' best guess is that you have Sideroxylon lanuginosum (Gum bumelia) shrubs.  The gum bumelia has long sharp thorns and produces blue berries.  Its leaves do somewhat resemble those of Punica granatum (pomegranate). It can grow to be more than 40 feet high but doesn't reach that height very quickly.  It can form loose thickets of shrubs that are hard to remove because of the long thorns.  Here are photos that show the long thorns and more photos showing the blue berry.

Here are a few photos from our Image Gallery:
