Title: Is Cissus trifoliata a food source for wildlife?
Answered by: Barbara Medford
Cissus trifoliata (sorrelvine) has somewhat fleshy leaves which may cause skin irritation for some people. The small berries are inedible, and the leaves have a bad odor when crushed. We could not find evidence that it is a significant food source for any wildlife, including the desert tortoise. Since there is the possibility of skin irritation, there might be some chemical component in the plant that is not good for consumption by wildlife, although we don't know this for sure. However, in view of the possibility of irritation and the bad odor, it does not seem worth it to keep it on your porch, if you would prefer to replace it with grapevines, thus providing leaves for your tortoise's dinner.
