Serre de la Madone (6 hectares) is a garden in France notable for its design and rare plantings.
Over the years he created a series of terraces among old olive trees, planted and tended by twelve gardeners.
In 1999 the property was purchased by the non-profit Conservatoire du littoral, who began restoring it to Johnson's design.
Today the garden contains a collection of unusual subtropical plants centered on a double pool, and rising in terraces.
Notable plant specimens include a superb Mahonia siamensis and Arbutus unedo, umbrella pines, Buddleja officinalis, Rosa chinensis, and bamboo, as well as good collections of cycads and succulents from around the world.
