You wait till they are already opening, about a quarter to halfway open. Yours haven't started opening yet, so they likely won't continue opening after cutting.

Oh boy i purchased these from flower shop wish i asked before, but now thinking probably should not have sold them like this either Thanks

uhhmmm.. those are seed pods .... they bloomed a week ago or so..

i would be kinda pissed at a florist who sold them as budded cut flowers...

yikes.. ken

Actually, the pods are pretty cool. Do they sell them like that on purpose?
