Phenology and Morphological Changes of Origanum vulgare L. during Introduction in the Precarpathian Region

Abstract

This study evaluates the introduction of Origanum vulgare L. at the Druzhba Dendrological Park (Precarpathian region). Field observations conducted from April to September 2025 on seed-grown plants assessed their adaptation, phenology, and morphology. Middle-aged generative individuals demonstrated peak viability, reaching heights of 42 cm with abundant flowering. Notably, the vegetation period was significantly extended, with flowering continuing until mid-September and senescence delayed until November, attributed to regional climate warming. The findings confirm the high adaptability and successful introduction of O. vulgare L., supporting its potential for large-scale commercial cultivation and recreational landscaping in the region.
