It is also famous for a nature reserve of about 90.33 ha with a very rare flora such as Trochetia parviflora which was rediscovered on a mountain slope in 2001, Pilea trilobata which was rediscovered in 2005 and the Mandrinette.
The Mandrinette (Hibiscus fragilis) is an extremely rare endemic shrub only known from steep slopes of the mountains Corps de Garde and Le Morne Brabant on Mauritius and from two further plants on Rodrigues.

In 1970 Andy Warhol made prints titled "Flowers" of the Mandrinette with petals in different colours based on a photograph by the nature photographer Patricia Caulfield, published in the June 1964 issue of the magazine Modern Photography.
