Located in the south of the town, this garden is an ideal place for family walks. Very popular, it also responds to a scientific vocation for the conservation of plant species from the five continents. In the spring of 2013, the Jardin des Plantes was enriched by a honey garden with a pedagogical vocation, which houses plants whose juice is used by bees to produce honey. The City of Rouen undertook the renovation of historic greenhouses, work on which was completed in 2019. The objective is to enhance the treasures of this extraordinary greenery (Ref. 1). "The collections reach more than 6000 species and the garden contributes to the development of sciences, to the preparation of medical students and to the dissemination of species, thanks to the exchange of seeds" (Ref. 10).

Project objectives

-Objective of the renovation of the greenhouses: "to bring to light all the treasures of this extraordinary greenery." (Ref. 1) -"Objective: to bring the premises up to standard, which will give access to the treasures hidden in this place, which is now partly closed to the public. These are 8,000 species that the curious will be able to discover after the work. Classic plants but also others much rarer" (Ref. 2). -To make this renovation a solidarity project (Ref. 2) -"Witnesses of a magnificent architectural past, the greenhouses of the botanical garden are among the rarest in France. Some of them are included in the inventory of Historic Monuments. Therefore, their restoration has become indispensable today for three reasons: -improve the working conditions of municipal agents -achieving significant energy savings -to strengthen the pedagogical and scientific vocation of the garden." (Ref. 2) -"The rehabilitation of aging structures, requalification of conservation areas, and greater accessibility to the public will make it possible especially to reinforce the landscape and historical character of the site but also to develop environmental education activities." (Ref. 6, page 1)

Implementation activities

-A public subscription is launched to individuals and companies for the renovation of the greenhouses of the garden plants. (Ref. 2) -Renovation of the greenhouses (15 in total) (Ref. 1) -Educational workshops and guided tour organized for adults and children (Ref. 1) -Hives and honeyflowers garden created in the garden in 2013 (Ref. 1) -"The central greenhouse, which dominates the perspective from its elevation, lightly bears its almost 170 years. Listed in the Supplementary Inventory of Historical Monuments, it shelters plants from an arid environment, Mediterranean utility plants and even carnivorous plants. In the aviaries, parakeets, parrots, Chinese quail, golden pheasants and other amazing birds compete in color with the surrounding flowers, while in freedom, peacocks, ducks and water turtles roam the edge of the small canal" (Ref. 1). -"Conservation and enhancement will partly take place in tropical greenhouses. They will host the most important collection of ornamental plants in the garden" (Ref. 8).
