These photos were taken last week on Vancouver Island. I am very curious about what the trees are. a type of willow? This tree was about 30 feet tall and just loaded with blossoms.
The first is an ash, I think Fraxinus angustifolia, maybe some cultivar of that. The second is black locust, Robinia pseudoacacia.
Ditto; the ash is likely Fraxinus angustifolia 'Raywood', by far the commonest cultivar of this species.
