The conservatory site was formerly a quarry and rubbish dump, purchased in 1971 by the municipality to create open space. The conservatory itself was founded in 1977 with a primary mission of preserving endangered species from the Armorican Massif (including parts of Brittany, Basse-Normandie and Pays de la Loire), France, Europe, and islands around the world, but also including plants from China, Japan, the Americas, Australia, and New Zealand. Since 1990 it has been designated a National Botanical Conservation Center to protect endangered and protected plants of the Armorican Massif.
