Jardin botanique de la Roche Fauconnière, Botanical garden in Cherbourg-en-Cotentin, France

The Jardin botanique de la Roche Fauconnière, also called the Favier garden, is a private landscaped park on a rocky height above the Divette valley, west of the former village of Octeville in Cherbourg-en-Cotentin, Manche. It holds 3,400 taxa, many from the Southern Hemisphere, among them eucalyptus, magnolia, Ilex nothofagifolia and Pseudopanax laetevirens. It was inscribed as a monument historique on 29 December 1978.

The garden was created in 1870 or 1873 by Alfred Favier and then kept up by his descendants Léon Favier and Dr. Charles Favier. It was inscribed as a monument historique by decree of 29 December 1978. It lies on a rocky height above the Divette valley, west of the former village of Octeville, which was merged into Cherbourg-Octeville in 2000 and became part of Cherbourg-en-Cotentin in 2016.

The garden is also called jardin Favier, after the family that created and kept it: Alfred Favier from 1870 or 1873, then Léon Favier and Dr Charles Favier. It occupies a rocky height above the Divette valley, west of the former village of Octeville, and has been inscribed as a monument historique since 29 December 1978.

Access is by prior appointment and guided tours are available to explore the plant collection. Visitors should expect uneven paths and terrain around the old manor house and wear comfortable shoes.

Among the 3,400 taxa grown here are Ilex nothofagifolia, a holly from New Zealand, and Pseudopanax laetevirens, both of which are rarely cultivated elsewhere in France. The collection was assembled by three generations of the Favier family: Alfred, then Léon, then Dr. Charles Favier.
