The reproduction ability of Primula veris L. plants was described on the basis of six-year observations on permanent plots in populations from natural localities. Cowslip individuals in different life stages were mapped according to topographical distribution. The vegetative multiplication symptoms of the plants were also recorded. The mean survival rate of seedlings to the juvenile stage was similar in both populations, amounting to about 16.5%. The highest survival rate was found for juveniles (44.3-57.6%) and immature (31.4-48.6%) individuals, while the lowest number of individuals turned from the virginile into the generative stage (2.2-5.7%). The efficiency of the generative reproduction measured by the ratio of the number of generatively recruited flowering plants to the observed number of seedlings was 0.22-0.42%, depending on the population.
