Looks like [FONT=arial,sans-serif][SIZE=-1]Red Osier Dogwood or could be Baneberry, or you might [/SIZE][/FONT]find it here... Search white berries
Open the bouquet out so you can separate out the shoots with the white berries, then take another photo which shows the branching structure and leaves (if any)
unfortunately it's not my bouquet, only managed to get a photo of it. thanks for pointing me in that direction Tipularia... I think I found it, Snowberries? Can anyone confirm this?
