How About A Snowball Fight?

Figuratively speaking, that is.  I'm referring to the beautiful Chinese Snowball Viburnum (Viburnum macrocephalum), which is a very interesting semi-evergreen shrub.  In my wanderings around this spring, I only saw a few.  What's fascinating about these beauties is how the blossoms start out chartreuse and then turn pure white. 

This one is in the yard of one of my friends. Unfortunately, I didn't have the opportunity to see if after the blossoms turned white.  The chartreuse color is very unusual, don't you think?  I really love it!
