Aggggghhhhh, this plant is still a puzzlement.
The lowest branch came out below the graft and I left it just to see what kind of flowers it had. As I have mentioned above, all the buds consistently fall off the main plant but this last time the root stock branch had two buds that held on. They were huge at 3 1/2" and 4" long. I've been impatiently watching them and today this is what I found. We did have a good amount of rain last week but plenty of sunshine and hot weather in between and this mix drains very well.
