[3][4] Plants are presented in rockeries (4500 m²) corresponding to four major themes: geographical origin, habitat, properties, and taxonomy.
The garden was abandoned during World War II, subsequently restored by Robert Ruffier-Lanche, declined again after his death in 1973, and revived in the early 1980s.
In 1998 it was recognized by the Conservatoire des Collections Végétales Spécialisées (CCVS), and in 2005 it became a part of the Joseph Fourier Alpine Station.
Joseph Fourier Alpine Station is a research and teaching institution of the university.
[6] The garden is also open to general public in the warmer months; an admission fee is charged.
