Q: Am I right in thinking that its customary to present the bride's mother with a bouquet of flowers during the course of the grooms speech? Does the grooms mother get one too? Are there any other traditions / formalities / presents I should know about at this stage of the day?
A: There are no hard and fast rules about this, so if you would like to present flowers to the Mother of the Bride after your speech this is absolutely fine. It's definitely polite to thank her in your speech, so you are publically acknowledging her position as hostess, along with the Father of the Bride, who is host. If your mother has helped with the planning or contributed to the day, then it's nice to mention her too.
As far as gift-giving goes, we would suggest doing this privately either before or after the wedding day. There will be plenty of flowers remaining after the wedding, which they will be able to take home and enjoy, so makes sense to think of something other than more flowers.
Practically speaking, there isn't much they can do with a bouquet on the night (other than to leave it on their table) so it is worth thinking of an alternative.
The groom is also responsible for covering the cost of the presents for the bridesmaids, pages, ushers and best man - according to tradition. These can be distributed after your speech, or at another occasion. We would advise getting the gift-giving out of the way ahead of the day, or after - that way it will be less likely for presents to be opened in front of your whole wedding party, forgotten or lost on the night.
