Ellerhoop-Thiensen Arboretum

In 1956 its last owner, Erich Frahm, established an arboretum (3.5 hectares) in cooperation with dendrologist Dr. Gerd Krüssman.

In 1980 the site was acquired by the state, along with 10 hectares for expansion, and a group including the Botanical Garden of the University of Hamburg helped plan its future.

Today the arboretum serves to help teach practical and theoretical biology, including both training in horticulture and academic botanical research.

Tree specimens include Acer rubrum, Aronia arbutifolia, Cephalanthus occidentalis, Chamaecyparis thyoides, Ilex glabra, Magnolia virginiana, and Taxodium distichum.

In recent years, the arboretum has amassed the largest tree peony collection in Germany, with a total of 245 taxa.
