Tilia americana IDed by buds. Could be little leaf linden, but most lindens buds have started to open already and these ones have not. (Post date is accurate)
Japanese Cherry (?)
Prunus serrulata IDed by flowers. The tree was behind a fence so I couldn’t really get a good view of the bark or buds to confirm my ID.
Row of Cleveland Pears
Cultivar of Pyrus calleryana IDed by small flowers with purple anthers and scaly bark.
Corkscrew Willow
[Revisited] Salix mataudana IDed this time by emerging catkins
Cleveland Pear
[Revisited] Cultivar of Pyrus calleryana IDed by small white flowers in clusters and tall height (over 20ft). Also, I IDed this tree as a callery pear in the winter using the buds, which made things much easier.
