According to the biogeographical zoning of Bulgaria, Eminska Mountain belongs to the Black Sea biogeographical region. Vegetation consists of mixed broadleaf forests of oak, elm, ash, and hornbeam. The mountainous part of the zone is occupied by deciduous forest with a predominance of Hungarian Oak, Turkey Oak and Beech association. The limestone areas are covered with herbaceous vegetation, such as Mugwort (Artemisia vulgaris) and Cornflower (Centaurea sp). Sand dunes are grown to plants such as Eryngium sp., Carex sp. and Tamarix sp. Wetlands are occupied by such species as the White Water Lily (Nymphaea alba) and the Summer Snowflake (Leucojum aestivum).
Numerous rare and protected higher plant species of national, European and global conservation significance occur in the region, including endemic species.
The territory is rich in herbs, wild berries and mushrooms. A great number of Bulgarian medicinal plants can be found here, such as St. John’s Wort (Hypericum sp), White Milfoil (Achillea millefolium), Marjoram (Origanum vulgare), Peppermint (Menta piperita), Medicinal Camomile (Matricaria chamomilla), and Common Balm (Mellisa officinalis), etc. Of the wild berries, the most widespread are Wild Strawberry, Blackberry and Raspberry.
