Why is my florist afraid to work with these flowers?

At the end of July, my wedding arrives. I'm not a 'Bridezilla" although I ve been through three planners, 2 photographers, and now possibly, at the last moment a new Floral decorator...Why?...Because, after quite a bit of research, I settled on a designer who i thought would easily meet my expectations...I decicided on varied height centerpieces, using a array of summer blooms such as dahlias, Cockscomb, Peonies, Hydrangea, viburnum, asiatic Lilies, Garden Roses, and anything else that may be available the week of my party. The colrs are a mix of all shades of pink, orange, peach, butter yellow and chartreuse...But now my 'Hero" informs me that due to poor crops around the world recently he will have a difficult time procurring these types of blooms, in these colors...(However, he CAN get the flowers I prefer in shades of Lavender, Cinammon, Chocolate,Celedon and Hot pink) Interesting, these are the exact colors (minus the pink) that both he and my Fiancee suggested. What to do?

Well umm you sound a little like a bridezilla it is your fiancee's wedding too he should get some say, besides it is just flowers trust me nobody is going to care what everything looks like i guarantee they will not even remember what color flowers you had, they are there simply to get fed their dollars worth of whatever gift they bought you and leave.
Reply:Perhaps you are asking the wrong question. From what you've said it seems there is a lack of the colors you want or is it the florist prefers the colors your future husband likes? For me, your question isn't clear. You imply that you are extremely particular, why would you "hero" lie to you? I suggest that you call the local floral warehouse and ask exactly what flowers might be available during your wedding week. If a warehouse is not available to you, call several local florists and ask the same question.
Reply:Call around and see if other florist tell you the same thing...if they do, then he is being truthful, if not...dump him and go with someone else....hopefully this is the only wedding you will have...it should be perfect.
Reply:As you guessed , he's probably lying . Why? - ???? The Viburnum %26amp; Peonies area stretch at the end of July , %26amp; they %26amp; Hydrangea don't hold up well in the usual July heat .Also become more expensive out of season .(What your fiancee is worried about?) Might be what he's worried about . If you are OK with that ( should hold up for the wedding itself - more than that - ???) let him know. Dahlias, lilies, %26amp; cockscomb , are most readily available in a mix , so the rest of it sounds like bs. Good Luck
Reply:How about Mums. They could fill in the colors the other plants would be missing? Also, consider flowers that could be 'dipped' in edged dye.
