Did u ever find out what your bush is , exactly? because it looks like the Korean Viburnum ... it has the most wonderful smell in the
spring (in Cincinnati, it has a very short bloom time in the
spring- I found out about Viburnum s at
spring Grove Cemetery, which is a famous 1800's architecturally landscape designed cemetery ... and they have an Arborist (?not sure on spelling) who might be able to tell you for sure...
