I saw several honey bees on white ferny flowers along a path near a little park in St. John’s today. I doubt they’re my bees, though you never know. I took this photo with my cell phone:

Honey bee spotted on white flower approximately 1.2km from our city hive. (August 02, 2012.)
The flowers are called False Spiraea. Or if you want get fancy: Sorbaria sorbifolia.

Identified: False spirea.
July 30th, 2015: I noticed the flowers of the dogberry tree is similar to False Spiraea, but on closer examination of the leaves in the photos, it’s clear they’re not the same. At least I don’t think so.
