Who gets a boutonniere/corsages at a wedding?

We weren't planning on giving any at all.but now i'm wondering if we should.Background- we are not having a wedding party. No bridesmaids, groomsmens, maid of honor..none of that. The only people to walk down the isle is the flowergirl and the bride. Casual wedding ceremony at a rose garden and then we're taking everyone to lunch at a nice restaurant. Trying to keep this day as simple as possible..our budget for the entire day is $1500. The only flowers I planned on buying was my bouquet and the grooms boutonniere, that's it. The Garden is full with roses and we aren't decorating the restaurant--it's nice enough.Should we get boutonniere and or corsages for people? Our parents? What's the point really?What a nice easy wedding that will be..congratulations I hope you and your fiance enjoy a long and happy marriage.To answer your question, there is nothing that says that you must have flowers at your wedding, but it might be nice if the mothers have a corsage and fathers have a bouttonnier. If you cannot afford it, you can always hit your dad up for a few extra bucks so they can have them..but again, there isn't anything that says they have to have it.
