Since 1952

Since 1952 begonias, tulips and trade have been the core business of A.F. Kolken & Zn. Arie’s pioneering attitude and ideas about cultivation and trade still form the firm basis of our company today.

1952
Start

Arie (Adrianus Franciscus) Kolken started in 1952, together with his wife Riet Kolken-Sijm, a flower bulb business on his father's parental farm with 1.2 acres of anemones and 40 acres of tulips. A cultivation that was familiar to Arie and which he was able to continue.

1957
Begonia cultivation in Holland

In 1957 Arie saw a field of begonias plants in Spanboek, grown on contract for a company from Belgium. These were tubers left over from the previous year. That year Arie visited the field with the begonias many times and fell in love with the product. However, this was not grown in the Netherlands. So Arie drove to Belgium in the spring of 1958, in search of knowledge and seed to grow tuberous begonias himself. There he collected his first 100,000 rooted begonia plants: the start of begonia cultivation in the Netherlands. 

1960
Commerce

Besides the nursery, Arie worked on a modest scale as an agent in flower bulbs. So it came about that the spirit of commerce was also an integral part of the business at an early stage.

1976
Company relocation to Dirkshorn

Arie's sons had been working in the business since childhood. When the location in Zwaagdijk became too small and expansion there became difficult, the company moved to Dirkshorn. From 1976, the company was continued here by the four brothers Frans, Theo, Aad and John. Here, based on technological developments, the cultivation was further developed and major steps were taken in automation of the cultivation processes.

1986-1998
Begonia, tulips and more

Over the years, various crops have been grown both in the greenhouses and in the fields. From anemone and shallots to cucumber and lilies. The main crops are tuberous begonia and tulip. With additional gloxinia as a perennial crop, a strong foundation is laid to make the best use of the greenhouses and fields all year round. During this period, several greenhouses were added to meet growing demand.

2000
Newly build warehouse

In 2000, part of the greenhouse complex gave way to a large warehouse hall, for production and processing of all crops.

2000
Introduction transplanting robot

In 2000, the first transplanting robot was purchased. A technological development that enabled the transplanting of begonias, which until then was all done by hand, to be taken over by robot.

2002
Founding of StoKolex

With the entry of the third generation, into the company in 2002, the export of the bulbs for forcing also got a boost with the establishment of StoKolex as a subsidiary company. From this base, the forcing export was started and expanded.

2014
Bloemenkwekerij 2000

Bloemenkwekerij 2000 becomes part of our company and with this the Liatris becomes part of our assortment. 

2017
Growing on sand base

The purchase of a farm site with land in Sint Maartensbrug expands the cultivation of begonias from clay soil only, to both clay and sand.

2016-2020
Innovation and efficiency

The techonological and sustainable developments continue, including the construction of a growing label greenhouse, a new transplanting robot and a rolling container system in the greenhouses. 

2022
Expand in export activities

With the takeover of P.A. de Groot Export, we expanded our forcing export activities to Scandinavia. All bulbs are processed, prepared and made ready for delivery from our new warehouse location in ‘t Veld.
