The planting plan arranges trees according to their geographical origins, their botanical families and their horticultural origins.
The largest geographical area covering 120 hectares was set out in 1965. It groups trees by continent (Europe: 250 species – Asia: 960 species – America: 700 species) and by region on each continent. Africa, South America and Oceania are represented only by a few rare mountain or southernmost latitude species.
Trees were systematically assembled by botanical affinity in the 50- hectare area first planted between 1924 and 1935. The magnificent rows of plane trees, American black walnut trees and Atlas cedars date from this time.
A 30-hectare “horticultural” area at the centre of the site displays tree cultivars These are varieties selected by humans for their ornamental potential or their strangeness.
The Arboretum is vast. Its 200 hectares offer nearly 20 km of paths to explore. Depending on your speed, count an average of 30 minutes walking time (2 km) between the most distant sectors (Bois de l'ancienne Pépinière - old tree nursery and Conifères nains – dwarf conifers) and the entrance. When you plan your visit, take care to calculate the time available before closing time!
The Arboretum may be visited by bike: a network of tarred lanes and metalled paths allow you to comfortably reach all areas of the estate. Please respect other visitors and vegetation by staying off the meadows and grassed paths and remaining only on these paths and lanes. Bike parking is available (see map) so that if you wish, you may continue exploring on foot.
