Chilean bellflower can live in your area. I have researched the toxic danger of the plant for dogs. As far as I can tell it is not on the toxic plant list for dogs. I not personally familiar with this plant. You might take a sample of the leaves, blooms, and berries to your local garden center. At our nursery/garden center here in Arkansas, we have people bring us samples to identify all the time. Having it physically in hand can really help in the identification process. There are so many little things that a photograph can properly show someone who is trying to make an identification. I don't know if Orange has a state extension office. I some times consult with our local extension office when I am making an identification. Hopefully someone reading the blog will have an answer. If you take it to a local garden center please let me know what they think it is.
