Rock Garden 
The Rock Garden, constructed in the spring of 1916, is, in point 
of time, perhaps, the first rock garden of any considerable size in 
a public garden or park in the United States. The rocks used in 
its construction are glacial boulders which were uncovered in the 
course of grading operations on other parts of the grounds; they 
are the only “native” rocks on Long Island, with the exception 
of one small outcrop on the northwest shore. The general idea in 
making the garden was that of representing a boulder-strewn slope, 
but this design, of necessity, was modified in places to provide 
proper cultural conditions as to drainage, depth of soil, and shade. 
The garden is planted with about eight hundred species and vari- 
eties of alpine, saxatile, and other plants suitable for rock garden 
culture. Persons interested in rock gardening will find Guide 
No. 5, The Rock Garden of the Brooklyn Botanic Garden, help- 
ful; also, Leaflets, Series XI, No. 6, The Rock Garden.
