Around the sidewalk café in the Water Garden (7, 1991) is a large pond with crystal-clear water, alive with underwater-plants during summer. Eye-catching is the Water Soldier (Stratiotes aloides). Countless green frogs, salamanders, aquatic snails, dragonfly larvae and leeches abound in the pond. The edge of the pond is lined with Japanese Horsetail (Equisetum japonicum). Late in summer white Balsam (Impatiens gladulifera 'White Queen') is prominent. All visitors are allowed to collect seed from it..

Later in summer Telekia speciosa, Marjoram (Origanum vulgare), Cup Plant (Silphium perfoliatum) and Aster x frikartii 'Mönch' make sure that there is still something worthwhile for the butterflies, though they like other parts of the garden better by that time.
Beyond the Butterfly Garden you'll see to the left the Pot square and Pergola (6, 1987), where a collection of pot plants is exhibited. Wisteria grows over the pergola, so too the rambling rose "Bobbie James', climbing Bleeding Hearts (Dicentra scandens) and Broad-leaved Everlasting Pea (Lathyrus latifolius). Under the pergola you find the entrance to the tearoom (B) and conveniences.

You then proceed along a fence covered with Akebia quinata, a vine and Apios americanum, the latter hardly visible until it flowers in September with pink, fragrant clusters of flowers, towards Behind the hedge (8, 1986). A cottage garden where everything is permitted, including a greenhouse,  weird volcano topiary, old-fashioned garden flowers and wild flowers, all combined together. This garden is being maintained by Pien van de Stadt. A striking plant in this garden is a prewar-cultivar of Marsh Mallow, Althaea 'Parkallee' with half-double, creamcoloured flowers. It reappeared in Eastern Germany after the fall of the Berlin Wall. Over the fence grows Clematis viticella, the gate is always open.
On the other side of the hedge is the Long Border (9, 1988). A border with imposing perennials 35 metres long and 5,5 metres wide demanding little maintenance. Outstanding are the two giant specimens of Persicaria polymorpha, which  continue to flower from the end of May until the end of September. Other prominent plants include Veronicastrum virginicum 'Fascination', Eupatorium maculatum 'Album', Helianthus 'Lemon Queen', Campanula lactiflora, Cephalaria gigantea and in front large groups of the unfamiliar Succisella inflexa, a member of the Scabious-family bearing pale blue roundish flower-heads at the end of summer
