While I am not a flower person, I have bought many floral arrangements over the years for people, and Flowers of the Field has some of the most imaginative and freshest arrangements I've ever seen.
They offer the classic arrangements, but also have several exotic flowers as an option. From a gorgeous single flower to an overwhelming arrangement, they do a good job with all of it. When I was there last, I even saw one arrangement that comes with an old Jim Beam sculpted bottle (shaped like a slot machine) as the vase.
Basically, they are my "go to" flower shop. A little on the expensive side, but you get your money's worth and the person who receives the flowers is guaranteed to love them.
