A sizable collection of peonies is yet another attraction in the garden. The ten beds are of slightly different sizes and make up a total area of about 150 m2. The beds are edged with discarded paving-edge stones, that are rather variable in shape.

Tree-peonies (Paeonia suffruticosa), Chinese-peonies (P. lactiflora), and common-peonies (P. officinalis) are planted here as well as some of the relatively new Itoh- hybrids. Itoh-hybrids were created by the Japanese gardener Toichi Itoh in 1948, and are the result of crossing varieties of tree-peony with herbaceous peonies. This hybridization process has resulted in some excellent hybrids, with large flowers held high above the foliage; they are hardy and have a long flowering-season. The large variation in peony species and cultivars ensures a long flowering-season for the enjoyment of visitors to the garden.

Clipped yews have been planted between the peonies, to provide structure and greenery in the winter months. There are also ten frames for autumn-flowering clematis to climb.
