The contradictory data on the distribution of Hyssopus taxa in Bulgaria are reviewed. H. officinalis subsp. pilifer is the wild plant growing in stony places with a temperate-continental climate. lts occurrence in two regions (Znepole and Mt Vitosa) is confirmed, and its alleged presence in the Predbalkan, W. Stara planina, and Mt Rila is discussed. The wild plants contain camphor, but not as much pinocamphone as the cultivated ones (H. officinalis subsp. officinalis), which is why the native populations cannot be used for perfumery purposes.
