Selected as Vancouver's centennial tree in 1986, Cornus 'Eddie's White Wonder' was chosen for good reason. If you live in or have ever had occasion to visit Vancouver in early May, you cannot help but notice these trees covered in a mass of white showy bracts. The bracts (modified leaves - not petals!) on this particular plant are still a bit green, so the plant will be at its peak in a few days.
For a brief blurb on this hybrid and the local nurseryman who developed it (Henry M. Eddie), read this short article: 'Eddie's White Wonder'.
The Chilliwack Museum provides more information on Henry M. Eddie.
