I planted three sorbus vilmorinii at the front of my bungalow three years ago. Two of the trees are developing strongly but the third is not so vigorous. Nevertheless all three produced a wonderful crop of pink berries last year. This year the weakest tree is flowering well, whilst the two stronger trees have yet to show any sign of flowering. Have you any explanation for the difference in behaviour? Is there any chance that the larger trees may yet produce flowers?
