Classified as one of France’s “remarkable gardens”, the Jardin des Plantes packs 10,000 species into its seven hectares.
The gardens are right in the middle of the city, just ten minutes on foot from the Château des Ducs de Bretagne.
It’s no ordinary park: The Palm House here is a fabulous late-19th-century metal and glass structure with plants from tropical America, while the three greenhouses to the sides have orchids from Africa and Asia.
As you tread the paths you’ll see mature trees like the 220-year-old magnolia and two huge sequoias that were planted 150 years ago.
