Le Jardin des Plantes, Nantes
Its a botanical garden, located in city centre. Locals are really proud of their Magnolias in there and they have one what is more than 200 years old.
Very nice place to visit.
Has ponds, grotto, palm house etc.
I think what they've done with the plants in this garden is amazing. They're so beautiful, and it's so different to see plants laid out in designs that way.
This is a really beautiful garden. If you're in Nantes in the spring or summer you must go check it out.
