The Flower District is a compact commercial enclave in the West 20s between Sixth and Seventh Avenues in the Flatiron area, where wholesale and retail florists have clustered since the early 20th century, filling the sidewalks each morning with buckets of cut flowers, potted plants, and tropical foliage. While the district has contracted with rising rents and competition from online retailers, it remains one of the city's most sensory-rich blocks — and one of the last surviving vestiges of the specialized trade districts that once defined Manhattan's street-by-street commercial geography.
