Some moron put in a bridal magazine (I don't know which one) a bouquet of white anemones and some other flowers calling it a fall wedding bouquet. I had the same problem with another bride. I gave her the very same options which she didn't like. I let the situation go and let her figure out what she wants to do. After visiting at least 3 other shops, she came back to me and decided on white calla lilies.
Sometimes you just can't make it happen on the budget they have. Anemones might be available in New Zealand but I doubt your bride will want to pay $1000 for her bouquet. Well...you never know! LOL
