Conservatoire du Bégonia, Botanical garden and begonia collection in Rochefort, France.

The Conservatoire du Bégonia is a botanical collection in Rochefort focused entirely on begonias, housing several hundred varieties and species under glass. The plants come from tropical forests and mountain regions, where they grow naturally in different climates.

This collection was founded in 1988 and honors botanist Charles Plumier, who discovered the plant during travels to the New World. The founding reflected a French commitment to botanical science and the study of newly discovered plant species.

The genus was named for Michel Bégon, intendant of the Rochefort naval port in the 17th century and a plant collector. In 1688 he sent the botanist Charles Plumier to the Antilles, where Plumier found the plant and named it begonia in honour of his patron's wife. The conservatory keeps that link to Rochefort's maritime past.

The conservatory is at 1 rue Charles Plumier, on the edge of Rochefort's historic centre beside the Charente, in a large horticultural zone. Guided tours run several days a week in early spring and late fall, and an admission fee is charged. The 2010 extension of 100 m2 was built with step-free access for visitors with reduced mobility.

The collection grows through international expeditions and exchange programs with other botanical gardens, particularly in South America and Cameroon. This global network allows the garden to continuously acquire new varieties and maintain the genetic diversity of the plants.
