Newest varieties

On this page you can find an overview of our novelty varieties. At De Bolster we are working towards a healthier planet and agriculture with perspective. In order to take the availability of organic agricultural crops to a higher level, we work hard on expanding our range of high quality seeds. For each crop we want to offer open-pollinated varieties, as well as hybrid varieties, giving commercial gardeners, arable farmers and individuals a wide choice of varieties for a successful cultivation.
