The Roseraies Tschanz SA was founded in 1948 by Mr Ernest Tschanz in Lausanne. Since then, the company has grown steadily while remaining a family business. We specialize in the cultivation of roses. At St-Prex, we cultivate 100,000 roses, including 350 varieties on an area of 13,000 square meters. The Roseraies Tschanz create new varieties each year, such as "Expo 64", "Bicolette" and "Charlie Chaplin". As a responsible family business, we pay attention to the efficient use of resources. That is why, for many years now, we have set up a unique water collection and watering system on our site in St-Prex for the cultivation of potted roses.
