    This paper presents the results of the investigation of the segetal flora accompanying the Virginia fanpetals crops in Łobez Commune. The purpose of this research was the identification and ecological analysis of weeds recorded in two plantations of the species cultivated for biomass energy production. The origin of the weeds was also determined, based on their geographical-historical classification. As a result, a total of 106 vascular plant species were recorded. The number of species was different in both plantations depending on the fertilising manner. The first plantation which was fertilised with industrial effluents from the starch factory “Przedsiębiorstwo Przemysłu Ziemniaczanego Nowamyl” in Łobez, was characterized by lesser diversity of the segetal weeds (42 taxa) than the second plantation, which was not fertilised (95 taxa). Both plantations were dominated by perennial species (78 taxa), which were twice as numerous as annual plants (28 taxa). In both plantations weeds were mostly represented by ruderal species of the Artemisietea vulgaris class and segetal species of the Stellariete mediae class. Apophytes were the most numerous historicalgeographical group in the flora (78 taxa – 73.6% of the flora), whereas non-synantrophic spontaneophytes were rare. Archaeophytes were the most numerous species (16 taxa) amongst the anthropophytes – most of them were the weeds of cereal crops and root crops. Inboth plantations also the American neophytes were recorded: Solidgo canadensis, Conyza canadensis, and Erigeron annuus, which are classified as invasive species in Poland.
