About us

Our story

After their education in horticulture and plant breeding, Christine and Robert Zollinger started with their own small seed company in Eastern Switzerland. Focusing on just a few traditional varieties, they soon started to expand their offer, until more land was needed. In 1991, they acquired a farm in Les Evouettes in the Swiss canton of Valais, where we are currently based. The family-owned company now offers more than 450 varieties that are especially well adapted for home gardens.

Our philosophy

Since the early 1980s, we are focusing on specialities and traditional varieties. They often have long familiy histories, having been selected over generations. They are perfectly adapted to local climates, and reflect their breeders' tastes and preferences.

We are proud to control the whole seed production process, and mainly sell our products through our website, allowing full control over our offer.

About our varieties

Most of our varieties have evolved over centuries, each generation of breeders selecting the best individuals, saving their seeds and sowing them in the following year. This led to perfectly adapted cultivars, disease-resistant and rich in taste.

Horticultural heritage

Especially valuable varieties are marked with our "Horticultural heritage" logo. They distinguish themselves from other cultivars in that they have a traceable history, are regionally relevant, open-pollinated and GM-free, and are perfectly adapted for home gardens.
