So I am having an October wedding, the 11th to be exact. it will be very much DIY and I plan to get the flowers for the centerpieces at a wholesale place (i did the same for my parent's 25th anniversary). I know that the colors of the centerpieces are going to be mainly white and ivory. I was thinking Roses with some Picasso calla lillies to add an accent color. I was wondering, however, if there were any other kinds of flowers (white and ivory) that could be included, since i know sometimes Roses can be a little pricy .. are there other pretty flowers that might put a little less dent on my wallet?
