Producing and processing seeds

400 Tonnes of production in 20 countries

At Hem Zaden we produce 400 tonnes of flower seed per year across more than twenty countries. In producing our seed we place great emphasis on sustainability, the welfare of our growers and a fair price for them and the consumer. During the production period, our varieties are constantly monitored to ensure consistent quality. The technologies we use to optimise seed performance differ depending on the species and variety, but one thing is a given: we only use natural products.
 
Seed cleaning and testing
As soon as the seeds are harvested in their respective countries, they are shipped to our facilities in the Netherlands for cleaning and processing. All seed lots are tested for germination in our in-house laboratory. We also have a large trial field where we test our seeds for varietal purity. By doing so, we ensure our products meet the highest international standards.

Reliable varieties
In tandem with our sister company, Hem Technologies, we work constantly on improving our varieties to make them even more reliable.

Trial field

10,000 square metres of trials

Every summer we test all the seed lots from the past season in our 10,000 square metre trial field to ensure the varieties are true to type, perform well and produce a good, balanced mix of colours, and to check that they are correctly labelled. By doing so, we ensure our products meet the highest international standards.
