A field experiment was carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz, Poland. The aim of the study was to characterize morphological achenes and determine the fertility potential and real of cup plant (Silphium perfoliatum L.) plants derived from micropropagation grown under irrigation. Low fertility real of cap plant resulted from the participation of infertile fruit-achenes it means devoid of the seeds. Due to the fact that this plant is entered on the list of invasive species, this property may be desirable during plantation establishment. As a result, the plant will not be so easy to penetrate into the ecosystem and will not pose a threat to native biodiversity.
