(not sure where and how i lost my cookie...)
can someone explain the significance of wearing daffodills?
and of wearing roses?

i recall a tradition in US where on mother's day flowers are
worn and one color signifies a living mother, the other one
who has died...

on further investigation here is the info (CARNATIONS)
Carnations are the most popular flowers for Mother's Day. ...
You wear a red carnation if your mother is still living or
you wear a white one if she is not...
