I hadn't any flowers for our wedding. Though all the vendors did recieve a Thank You card only as their services were paid for as the gratuity charge was applied by the venue. No tipping from our end at all.
I wouldn’t tip the florist. Only people I’m tipping are my makeup and hairstylist, and my DJ. And all the staff at the venue (charged a gratuity).
I figure if I’m buying a product from you, I’m paying for that product. To me a tip is when you receive service and I only tip when good service is received. So if my DJ sucks. Well then they won’t get a tip.
If someone is delivering/setting up flowers, you could give a small tip/bonus, but I would say it's not expected. Perhaps even wait to send a thank you card, you could include any guests comments or compliments on the flowers.
I'm thinking about 15%. and a nicely written card. The florist I am using owns the business herself. but she will be delivering the flowers (and its about a 30 minute drive). And I have known her for a number of years (he husband and I used to work together). so I just want to give her a lil something. i'm also debating about a small nice present too.
