Who are we ?


SEM PLUS has been a part of the Drôme Valley for many years.
Originally, our family business revolved around farming and cereal cultivation. However, starting in the 1980s, we specialized in seed production and trade. Seed garlic is now at the heart of our productive activities.
Our structures are deeply connected to the region where they originated and thrived, and we hold a strong attachment to it.
Adapting to market demands, we expanded our offerings to include seed onions and shallots. Since acquiring SEM PLUS in 2001, we’ve been growing our commercial activities.
