Some years ago, while living in Belgium, I was a regular vistor to the first Amadeus, which was the exquisite flower shop of Tom's father Jan. Also in the center of Leuven, Jan's was one of the first shops in Belgium to create a unique Belgian floral style by combining historical and modern elements. In fact, Amadeus was so beloved, that when it closed, a rose was named in its honor. Nackaerts, the younger, most certainly learned much at his father's knee. Evidently, the apple doesn't fall far from the tree!
