More than half of the plants distributed at the East Black Sea region are present in the Rize province. 70 % of the plants are of medicinal and aromatic value. 4 Mentha species, 3 Origanum species, 3 Thymus species, 2 Salvia species, 2 Stachys species and 1 Calamintha species were collected from 19 different localities in Rize during 2015.

Traits like plant height, number of branches, stem diameter, leaf area, dry drog weight, fresh drog weight, dry drog yield, fresh drog yield, seed weight and essential oil yield were determined. Principal Component Analysis was performed to assess the diversity regarding with the investigation of characters. Based on obtained data large diversity could be determined. Collected materials can be used as genetic resources for further investigations. Keywords: Lamiaceae, medicinal and aromatic plants, characterization.
