You have before you the Van den Berk Rhododendron GmbH brochure and we are delighted to be able to introduce our rhododendron nursery to you. Van den Berk Rhododendron GmbH is located in the northern German town of Rastede. Here the 50 hectare site is dedicated to the cultivation of numerous species and sizes of rhodo- dendrons and azaleas. Since 2006 the nursery has been a subsidiary of Van den Berk Nurseries whose 500 hectares make it one of the largest nurseries in Europe.
Today, the rhododendrons have become a highly valued part of our extensive range and in terms of size, these plants are a perfect addition. There are more than 160 species large-flowered hybrids, yakushimanum hybrids and azaleas, and they are grown from around 70 cm up to 4 metres in height and width. Whether you need large numbers for planting in large beds or striking solitary plants, both are abundantly available and always of exceptional quality.
In this brochure we would like to introduce our rhododendrons to you. Our sales team staff will be able to inform you about prices, sizes and species. If required they will also be able to advise you or arrange a visit to the nursery. You will be warmly welcomed!

For several growth seasons after planting, the flower buds are nipped out of the plants. This stimulates the plants to concentrate all their energy on the development of branches and leaves instead of flowering and forming seeds. This labour-intensive treatment and regular pruning of rhododendrons results in compact, full plants. These plants are wider than usual, don‘t fall apart as quickly and also look good outside the flowering season.
