Organised with great care, trees and bushes from the same botanical families are grouped together around the garden.
For example, the walnut family, the berberis family, etc. This creates a more coherent space. Perennials from mountain ranges across the world (e.g. flora from the Alps, the Caucasus, Japan, Chile, etc.) grow near the waterfalls.
* Flora of the Amorican Massif
1500 regional species of plants grow in this “outdoor library” and are grouped by family. You can even discover some rare plants here (for example the wild Sylverstre tulip) or plants that have completely disappeared in the wild (Marsilea quadrifolia).
* Medicinal plants and toxic plants.
Successor of the 17th century Apothecary Garden, this plot is dedicated to medicinal and toxic plants and is still used as a lecture support for pharmacy students.
Nantes' Camellia collection is unique in France: more than 1000 varieties in the city as a whole, of which more than 500 grow in the Botanic Garden. This collection is officially recognised as a national reference collection. The varieties on display include camellias created in Nantes, such as the Ville de Nantes.
* The mountain and the grotto
The rock gardens, grottos and belvedere “mountain” were designed to be entertaining features of this English style garden. Dominique Noisette, the landscape architect who co-designed the garden in the 19th century, created these in line with the style of the period.
Since 2013, a collection of ferns has grown close to the Clémenceau entrance.
* Carnivorous plants
Since 2012, carnivorous plants have grown in the outdoor peat bog and in a cool greenhouse. It’s a rare opportunity to see these plants up close and understand the different ways in which they trap their prey. They are especially popular with children.
The pollen sentinel in the Botanic Garden is unique in France. It’s composed of 20 species of local plants that trigger allergies. It provides information on pollen emissions to a specialist medical network.
* The "flower palette"
These square beds are replanted twice a year and display all the flowering plants chosen to decorate Nantes’ roundabouts and roadside flower beds.
