This establishment dedicated to garden innovation lies to the southeast of the centre of Angers. An avenue of oaks leads to the house of its founder, botanist Gaston Allard (1838-1918). The 7 500m2 of grounds around the building are given over to annual and perennial plants, bulbs and shrubs. There are also contemporary sculptures and potted plants. Beyond, a little sensory garden is laid out around a rectangular pond with water lilies.
