Thank you for your reply. The birds planted the morning glory. Always been cautious about those myself. They go to my neighbors who limes to ant unusual plants and they deposit them in my yard. So I never know what will pop up.
We have rescued a Sonoran Desert Tortoise a few years ago. he was very small at that time and insisted on continually crossing the road. He is now much larger and I have questions about the type of plants I can feed him.
I have ruellia growing like a weed all over my yard, Mexican primrose...
