can i still throw flowers on stage? if yes, what kind of...
Not in UK, I'm afraid.
In May Liverpool a security guard was trying to take away my friend's flower,
although my freind wasn't intend to do so.
In the end she had to ask other friends, whose seats were not very close to the stage, to keep it.
According to the security, if you throw flowers to the stage Morrissey may trip and hurt himself.
