Bpcyclist, I am so sorry to read about the loss of your friend and his sad loss of life.

I am not sure of the etiquette on this either, given the time that has passed. Not knowing his family makes that harder for me to share an opinion. However, if someone sent me flowers in memory of my mother's too young passing, I would be greatly touched, even though my mom passed away 15 years ago. It's hard to know where others are at only one year. I was still very much disturbed after only one year, but at the same time I remember wishing that people acknowledged my grief more than many did. It is a hard call.
