I am having foam flowers, they look just like the real thing, a lot less expensive plus your bridesmaid either get to keep them or you can sell them on again after the wedding.
I have just bought (this morning)
1x teardrop rose bouquet with diamantes, pearls and ribbon
3x bridesmaids posies with all the bits mentioned
1 x Double buttonhole for groom
2 x corsages for mums
38 buttonholes for guests (its an informal destination wedding no suits allowed so want them to look part of a wedding party)
3 x table centre pieces
3 x Cake topper flowers
total £183 which includes p+p
my budget was £150 but that didnt include table and cake flowers so happy with that price.
All my guests can keep their buttonholes, bridesmaids keep theirs and will eventually sell my flowers, the cake and table flowers so should get a little bit of that back at some point. xxx

This isn't helpful to you I know, but we didn't budget anything because my MIL is sorting them all!

I had no idea how much to budget so I went to see a florist and got a quote for £500. Thats for bouquet for me, 2 x poseys for BM's, 7 x button holes, 5 x corsages, 1 x long table runner (for top table) and 5 x table centres. Mum and I thought it wsa quite a good price :)

£60 , I am buying bouquets and doing them myself. No I am not a florist, just willing to do it myself than pay £200+ from florists. were not having buttonholes though lol x x

I really got lucky here as my package with the venue includes all the flowers i need there and my sister is a florist so she is going to get all the flowers for the bouquets, corsages & button holes and make them all up for without costing me a penny it will all be our wedding gift. have no idea how much what we are having would have cost otherwise x

I think I've spent about £700.
That's for my bouquet, 5 bridesmaid bouquets, 4 lapel corsages, 8 buttonholes, 4 childs buttonholes, a flower girl wand, top table display and 9 table centrepieces.
