De Bolster,  specialist in organic seeds


We are a family company that started in Epe (The Netherlands) in 2005. De Bolster was originally situated in the northern part of The Netherlands and was founded by Harry and Chris Douwes in 1978. Bart and Elly Vosselman (center of the picture), together with their son Frank (left side of the picture) and business partner Patrick Hoogendoorn (right side of the picture) shared the passion for organic seeds and breeding, and continued De Bolster as it is today. What started as a small company, with all its activities located in the old farm, further developed and professionalized to a specialised company with around 20 employees today.


In 2015 we sell over 390 varieties to professional growers, seed companies, retailers and hobby gardeners. We also offer seed multiplication and cleaning for other professionals. We are a respected brand in organic seeds. The seeds we produce are organic vegetables, herbs, flowers, green manure and sprouts. Next to that we have our own breeding programs in both winter and summer squash and tomatoes. Currently we are market leader in orange winter squash for the fresh market in The Netherlands.

Today we are a specialist in organic winter squash, tomato, beans and pepper. All varieties that fit to the philosophy and vision of (professional) organic agriculture. We sell our seeds in small packages and bulk with our own De Bolster label, but we also offer our seeds in private label. 

Our motives

Fortunately more and more people realise that seeds are a part of our cultural heritage. A part of our history we have to be careful with. That is why we, at De Bolster, respect biodiversity and offer a wide range of crops and varieties.

We also want to help the organic sector to move forward. That is why we put a lot of effort in developing new varieties. We are proud to tell you that we already developed several varieties especially for organic agriculture. 

Beside our own developed varieties, we exclusively offer organic seeds from professional varieties developed by external breeders. These professional varieties are a real benefit for organic growers! That's why we are glad to sell these varieties too.

Our keywords 

We have a passion for seeds and sustainability. We prioritise high quality and we want to be an involved and innovative partner, who helps to develop and optimise the organic sector worldwide. We therefore actively participate in multiple projects and debates that are related to the development of organic agriculture. But above all:

We are an authentic, personal and reliable organisation.
