This building has been called "a capitol at Washington, for the government of roses and sweet violets -- a splendid flowery fane." The architect was W. L. B. Jenney, of Chicago, and he covered a site nine hundred and ninety-eight feet long by two hundred and fifty feet wide. In the center he built a large dome, one hundred and eighty feet high. The style of Horticultural Hall was called Venetian Renaissance, and the meaning of that description may best be noted in the facades and roofs of the terminal pavilions, where the hip-roof is observed. The building was decorated with a sculptural frieze and six single figures, all by Loredo Taft, of Chicago. The total cost was $300,000.
