The systematic sections reflect phylogenetic relationships between plant taxa. In accordance with the current state of research the Flowering Plants or Angiosperms are split up into three major groups: Basal Angiosperms (under construction), Monocotyledons and Eudicotyledons. 

Mountain species and alpine plants are arranged in the rock garden. This section is currently being redesigned. 

The Mediterranean section hosts a number of half-hardy species from different parts of the world with a Mediterranean climate. Many of these specimens survive the Belgian winters owing to the Botanical Garden’s favourable location and to the Mediterranean section’s microclimate in particular. 

 
The arboretum is broken down into three ‘regions’: Europe, Asia and America. Labels mention the species’ name and family as well as its natural distribution area. The arboretum’s inventory is available on-line through the PLANTCOL project.
