I don't know if they are difficult or not, but I recently attended a wedding that this florist provided flowers for and all they did was place some calla lilies in a vase for the ceremony and cross some calla lilies on the reception tables. I had another friend that did the flowers for her own wedding with flowers from Costco that looked better than this.
Gift shop yes..wedding florals no.
I hired this florist for my weddiing and was very unsatified with what we received. I would recommend using another florist with a more creative artistic style which is what I thought we were getting instead of the old school florals that arrived.
