It seeds itself sparingly, but these bushes are all from little plants that started their life as a seed in the decomposed granite in the parking area in front of our house. The three original plants are alongside the garage wall. If I caught them early enough, and the conditions were right, I moved them. This one out by the road.
I always meant to move these two in the granite but never got round to it and now they have to stay. No one can park here any more. If you look closely at the flowers you will recognize them as belonging to the Scrophulariaceae family.
Another one I moved to the berm at the back of the house and outside the fence. Give them rain and high humidity and they burst into flower.
What a treat.
