The Perennial Collection contains over 788 taxa, i.e. species and varieties of both botanical and ornamental plants. A meandering lawn in its centre highlights the compositions of perennials growing in irregular beds against a background of interesting species and varieties of ornamental trees and shrubs. The perennial species planted here flower from early summer to late autumn. These include groups of asters (Aster) and sneezeweeds (Helenium). Rock garden plants are presented on a stony hill. These include spring-flowering perennials such as Bergenia cordifolia, Adonis vernalis, Alyssum saxatile, and Aubrieta deltoidea. Stone walls and a wooden palisade form terraces on the slope intended for semi-shaded plants. Species and varieties of Ficus (Hosta) constitute the most numerous group here.
Water flows down the stony hill with mountain plants into two small ponds. One of them is home to the four-leaved marsilea (Marsilea quadrifolia) and a full-flowered variety of marsh marigold (Caltha palustris ‘Multiplex’) with an increased number of petals. Walking along the stone path in the middle of the large reservoir, across the bridge of the second smaller one, or going around the lower reservoir, we can admire plants with floating leaves (e.g. the white water lily – Nymphaea alba, the yellow water lily – Nuphar lutea, water lily – Nymphoides peltata), underwater plants (e.g. Canadian waterweed – Elodea canadensis, stiff hornwort – Ceratophyllum demersum), or rushes (e.g. broad-leaved cudweed – Typha latifolia, calamus – Acorus calamus).
