Bear garlic (Allium ursinum L.) has been well-known to popular medicine for ages and its pharmacological action is similar to that of common garlic. It is a typical geophyte; occupies wet habitats in ravines and near springs, mainly among beeches and riparian forests. Generative reproduction is the main way for population spreading. The present study aimed at evaluating the influence of mulching using pine bark and varied nitrogen nutrition rates (0; 75 and 150 kg N^.ha^-1) on flowering traits of bear garlic under conditions of the field cultivation. Mulching using pine bark had positive effects on the length of inflorescence shoot, peduncle, inflorescence diameter, as well as number of flowers in the inflorescence and the plant. During a month, i.e. since April till May, significant increase of inflorescence shoot length at bear garlic has been recorded. In April, they length ranged from 9.0 up to 59.8 mm, while in May from 190.5 to 320.8 mm. Bear garlic inflorescences consisted of 13.4 to 24.0 flowers, with their diameters reaching 19.0 to 53.8 mm. The longest inflorescence shoots and inflorescences with the largest diameter and flower number were produced by bear garlic in the third year of vegetation. No remarkable influence of nitrogen nutrition on inflorescence shoot length and number of flowers per in an inflorescence was recorded.
