Leucojum vernum L. (Amaryllidaceae) is a bulbous geophyte from Central Europe known as medicinal and ornamental plant. Native population of this species can be found in the Peres Forest (parcels number 23-24) from Velyka Dobron Wildlife Reserve (Western Ukraine), monitored continuously since 2014. The aim of this study was the morphometric evaluation of the species and the chemistry analysis of the soil in which the species grow. According to our results the length of leaf sheath was the most variable parameter from the evaluated morphometric indicators (number of leaves, maximum leaf length and width, bract length, leaf sheath length, scape length, and bulb diameter). Correlations were found between maximum leaf length and scape length, but also between maximum leaf length and bract length. Soil chemistry analysis showed that the chemical properties of the soil are favorable for the studied plants. The soil pH was slightly acidic, the humus content and the supply of alkaline hydrolyzed nitrogen were high, and the amount of soluble P2O5 was moderate. Differences between the territories were found with respect to the soil agrochemical parameters.
