Jardin botanique de Bayeux, Botanical garden and historical monument in Bayeux, France

Jardin botanique de Bayeux is a 2.6 hectare garden displaying hundreds of tree species arranged throughout landscaped sections. The space features wide pathways that connect different plant collection areas set in varied terrain.

In 1851 Charlemagne Jean-Delamare (1772–1858), a naturalist and member of the Société linnéenne de Normandie, bequeathed a meadow to Bayeux for a horticultural teaching garden, adding 28,000 francs. The botanical garden never materialised; Eugène Bühler (1822–1907) instead landscaped a 2.6-hectare public park, opened in 1864. The park, its south approach avenue and two entrance pavilions were listed as monuments historiques in 2007.

The garden is named after Charlemagne Jean-Delamare, the naturalist and municipal councillor who gave the land to Bayeux for a horticultural teaching garden. A bronze bust of him by sculptor Pierre Hottin was erected in 1880; it was melted down under the Vichy regime and replaced by a stone bust.

The garden lies at 53, route de Port-en-Bessin, northwest of Bayeux's centre, and is open daily without charge. The south access avenue and the two entrance pavilions are listed, so enter from that side to see them. The lawn and paths are level, with the weeping beech standing on bare earth.

The weeping beech was named a natural monument in 1932. Its 1938 metal frame was replaced after 2001 by a net held by four masts, from which the branches hang in straps, free to move. The tree may be a graft between a common beech and a false de Verzy.
