This is Cape Leadwort Plumbago, it is white instead of the blue one that you see often. It is doing great in this location and is full of blooms. We have planted some blue ones in the past that were not happy where they were planted.
This is the first year for it to do so well I contribute that to all the rain we have had.
We have a lot of blooming bushes and shrubs in our yard one day I need to do a post about everything that is blooming.
