These were planted at the same time, about 3 years ago.
Two have beautiful white flowers and one is just green, no buds at all. It looks healthy.
I have lawn and tree service and about 4 weeks ago they sprayed.Do you think it may have been the chemical they used?
It was a very windy day and the solution was all over the window above the flower.
I have since cancelled the tree service. I told them "had I just washed my windows I would have been very angry".
