The study presents vascular flora, both spontaneous and that coming from former and contemporary plantings found in five palace parks in the Wielkopolska region. Analyses were conducted in the years 2010–2013. A total of 612 vascular plant species were reported. In terms of the floristic composition the park in Wąsowo was the richest (335 species), while the park in Konarzewo was the poorest (133 species). Interesting plants occurring spontaneously in the analysed area include Alisma ×rhicnocarpum, Asperugo procumbens, Cardamine flexuosa, Cardamine hirsuta, Cerastium macrocarpum, Geranium molle, Monotropa hypophagea, Oxalis corniculata, Stellaria neglecta and Vicia dasycarpa. The most interesting species grown or probably purposefully introduced to the parks include Acanthus longifolius, Aegopodium podagraria ‘Variegatum’, Chaerophyllum aromaticum, Corydalis cava, Corydalis intermedia, Cymbalaria muralis, Euphorbia amygdaloides, Gagea minima, Geranium pyrenaicum, Geranium sanguineum, Gypsophilla paniculata, Helianthemum apenninum, Isopyrum thalictroides, Lithospermum purpurocaeruleum, Luzula luzuloides, Narcissus pseudonarcissus, Origanum vulgare, Ornithogalum nutans, Poa chaixii, Rudbeckia fulgida, Telekia speciosa and Viola cyanea.
