The paper presents data on the occurrence of host plants of Cuscuta lupuliformis, indicating the preferred species and assessing the parasite’s development. Field research was conducted in 2017–2018 along the Vistula river valley within the city of Sandomierz (S Poland). Thirty-one host plants belonging to 14 families were identified. Dodder infected mainly Chaerophyllum bulbosum, Salix alba, S. fragilis, S. purpurea, S. viminalis, Rubus caesius and Urtica dioica. The families most attacked were Salicaceae, Asteraceae and Rosaceae (Fig. 1). Dodder intensively attacks species such as Acer platanoides, Artemisia vulgaris, Fraxinus excelsior, Lonicera tatarica, Salix alba, S. fragilis, S. viminalis, Rosa canina, Rubus caesius and Sambucus nigra. The diversity of hosts was highest near the city center. One dodder plant can parasitize several unrelated host species at the same time.
