Identifying Vines


Grape Family 

Vine I

FINALLY! The identification for this vine has been very difficult. It is not aggressive in my garden but it is persistent.

At first I thought it might be western poison-oak or fragrant sumac Rhus aromatica based on the leaf shape. The leaf is waxy and has a strong peppery scent reminiscent of roasted sesame oil. Thanks to a persistent “image search,”  I believe it to be Cissus trifoliata. I found it at, Sheryl Smith Rogers’  Window on a Texas Wildscape blog. She says,"Sorrelvine, cow-itch vine (Cissus trifoliate), is a member of the grape family. According to Wildflowers, Trees, and Shrubs of Texas, it can cause contact dermatitis in some individuals."
My botanical reference book does not include this vine under the scientific or common name.

This vine is first spread by birds depositing seeds and then the very aggressive vine spreads through an highly efficient underground roots system.
