Title: Thorny plants for a security perimeter in Austin TX
Answered by: Nan Hampton

QUESTION:

Hello, I am trying to establish a security perimeter around my property that incorporates thorny or otherwise deterrent shrubs and vines. Can you recommend some attractive native plants that would suit this purpose? Flowering would be a plus, but not a priority. I am in West Oak Hill in Austin, TX. Thank you!

ANSWER:

Here are some thorny plants that grow in Travis County that would make an unpleasant barrier to cross:

Mahonia trifoliolata (Agarita) is an evergreen shrub with very prickly leaves.   It has small fragrant yellow flowers in the spring that produce edible red berries.

Acacia farnesiana (Huisache) has yellow flowers and lots of small thorns.  Its common name, huisache, is derived from Nahuatl and means many thorns.

Mimosa aculeaticarpa var. biuncifera (Catclaw mimosa) has recurved prickles along its branches and showy pink flowers.

Zanthoxylum hirsutum (Texas hercules' club) has prickles on its branches very much like a rose bush.

Zanthoxylum clava-herculis (Hercules' club) also has very spiny branches.

Sideroxylon lanuginosum (Gum bumelia) has sharp thorns along it branches.  Here are photos from the Image Archive of Central Texas Plants that show the thorns.

Smilax bona-nox (Saw greenbrier) is a vine that forms thick tangles and has sharp, stout prickles that discourage movement through them.

You might mix these shrubs and vines to make an attractive, but formidable, barrier.  Most of these do have attractive flowers and many are fragrant.
