%X The study was conducted in the years 2009-2010 in the UMCS Botanical Garden in Lublin. The observations involved the flowering time and the seasonal and diurnal dynamics of flowering and pollen production in flowers of the liverleaf (Hepatica nobilis Schreb.) from the family Ranunculaceae. The liverleaf begins blooming in early March and the full bloom occurs at the end of March and beginning of April. All-day observations demonstrated that the flowers opened between 8 am and 3 pm, and pollen was released from the anthers between 10 am and 4 pm. The mean weight of pollen produced by 10 liverleaf flowers was estimated at 7.4 mg (1.85 mg/100 stamens). An impact of the weather on the flowering period as well as the seasonal and diurnal dynamics of flowering was observed. Among insect pollinators, the honeybee dominated with a density of 4 individuals per 1m2 of a flowerbed that contained 74 open flowers on average.
