Legendary florist Katsuya Nishimori first made a name for himself as the chief floral designer at the floral shop inside the Japanese department store Takashimaya. When Takashimaya shuttered in 2010, Nishimori and his team opened up their own place in Flatiron. They’re known for daring, architectural arrangements with a distinctly Japanese aesthetic. Most of the flowers come from their organic farm in upstate New York, about eighty miles north of the city.
