This photo of me and one of our gopher plants shows how tall gopher plants can be. I like the look of these plants, but they don't seem to completely repel gophers. We have gophers living three feet from our plant, and the gophers are munching away on our vegetables in a most alarming manner.
Before posting this photo I researched these plants, Euphorbia lathyris, AKA Gopher spurge, Cape spurge, Mole plant or Mole spurge and read that the white sap is very toxic, so be very cautious when handling the plant or cutting it. People have gone to the ER room because it caused an allergic reaction with severe itching and swelling on hands and face.
I read that the gopher plant can spread so much by its seeds that it is considered a noxious weed in some areas like the Pacific Northwest. Here at our home in California it hasn't spread and we have two large plants.
Have you grown gopher plants? Did they repel gophers?
