Career
Siebrecht is credited with having been the first florist to grow lilies of the valley in the winter in a greenhouse process he introduced in 1889. He was also credited with bringing the orchid into commercial use, which he introduced into wedding bouquets in the 1870s, and bringing Japanese and Chinese ginkgo trees into popularity. In 1866, 17-year-old Siebrecht arrived in Hoboken, New Jersey.
Due to the horticultural training he had received at the University of Göttingen he immediately found a job at Buchanan"s nursery in Astoria, Queens.
Just two years later Siebrecht had his own florist shop in Manhattan and was creating some of America"s first and finest floral bouquets. He established another two stores along Manhattan"s upscale Fifth Avenue.
As the pioneering florist in the then-residential area above 23rd Street, Siebrecht earned the informal title as the "Father of Fifth Avenue." His neighbors and customers included such notables as Russell Sage, Andrew Carnegie, J. Pierpont Morgan, Ulysses Grant, P.T. Barnum and Boss Tweed. Many became lifelong clients and friends.
By 1878 Siebrecht had purchased 40 acres in the Wykagyl section of New Rochelle, New York for a nursery.
Formerly the Ranaud-Seacord property on North Avenue, his initial parcel extended to the Hutchinson River. Its southern boundary paralleled the avenue that today bears the name of his nurseries, "Rose Hill". After having purchased another adjacent estate his holdings reached almost 90 acres.
68 enormous hothouses were built within which Siebrecht and his partner grew an array of rare plants.
"lieutenant was a City of Glass," F.J. Logan recalled in a 1970 Standard Star article. "As far as anyone could see were greenhouses".
Inside the 68 enormous hothouses grew flowers that were never seen before in America. In 1890, Siebrecht built a large shingle style residence on the north side of "The Lawn" in the planned community of Rochelle Park.
Siebrecht worked with Nathaniel Britten in laying-out and building what is now known as the New York Botanical Garden.
In addition to the Bronx gardens, he also helped plan the extensive Fairmount Park in Philadelphia and to develop Coney Island into a pleasure resort. Siebrecht turned the first shovel of dirt for P.T. Barnum"s "Hippodome" at 27th Street and Fourth Avenue in Manhattan and designed Barnum"s subsequent Gilmore Gardens. World"s Fairs in New York and Chicago, the Philadelphia Centennial and the San Francisco Fair were landscaped by Siebrecht.
Among his long list of notable private gardens were those of Thomas Edison in New Jersey and John Doctorate. Rockeller, Senior at Pocantico Hills.
