Mini Plums....is what we have named these lovely berries. They bring color and beauty to our living room window every year from it's 5-petaled white flowers in February to it's dark purple fruits in July. This year's long and hot summer has brought out much more of the berries than usual. Some swallow-like birds have made nests within it's thorny branches and waxen leaves and would be residents until their little speckled eggs hatch. I have no idea if these fruits are edible at all since none of our feathered bipeds seem to show much interest in them. Does anyone know, because if it is edible, I can make a lot of Mini Plum pies
