We take care of the preservation and propagation of vegetables


DSP Ltd is maintaining and propagating varieties of vegetables species bred by the Swiss research stations for agronomy, amongst them the famous "Zefa" varieties, as well as ameliorated local varieties. For this purpose, DSP Ltd works together in a network with growers who produce either organically or conventionally.

Numerous varieties commercialized by DSP are especially demanded by amateur gardeners searching specialties and authentic flavor. Such niche products contribute to the conservation of varietal diversity.

DSP provides the wholesale with seeds and offers service features to the commerce of vegetables grains.
