About the Arboretum Wespelaar

Arboretum Wespelaar vzw, a non-profit organisation, was set up in 2001 to manage the botanical collections of a part of the estate of Philippe de Spoelberch in Haacht-Wespelaar situated to the North of the garden of Herkenrode (Belgium).

In 2007, the arboretum and its collections were donated to the Foundation Arboretum Wespelaar which was set up to guarantee the future of the collections and arrange for their opening to the public in 2011. Some 2310 different taxa can be seen on the 20 hectare grounds.

The arboretum brings together trees and shrubs from around the world which can survive in the temperate Belgian climate. Arboretum Wespelaar houses many woody species large and small, including common and rare species, especially those that are threatened in the wild.

Some genera are particularly well represented: Acer, Magnolia, Rhododendron and Stewartia. In addition to these, you will find good collections of other genera such as: Betula, Carpinus, Euonymus, Hydrangea, Ilex, Tilia, Viburnum, Quercus, Styrax etc.

The visitor centre and arboretum opened to the public on 17 April 2011. The private garden Herkenrode is only open to guided groups on request or to members of asbl Jardins ouverts – Open tuinen vzw (

The Arboretum is open on Wednesday and Sunday from 10am to 5pm from the 1st of April to the 15th of November. Groups are also welcome on other days on request. For more information, please consult our website the dutch version of the site also offers a virtual tour through the collection
