sagedusteni

Sagedusteni is a species of flowering plant in the mint family, Lamiaceae. It is described as the sole species in the genus Sagedustena. The name sagedusteni reflects its sage-like aroma and its dusty leaf texture.

It is a perennial herb with square stems, opposite leaves, and dense inflorescences of small tubular flowers that are pale purple to lilac. Leaves are elliptical to lanceolate, 2–7 cm long, with a soft, hairy coating that gives a dusty appearance when dry.

Endemic to arid scrub and Mediterranean habitats in southern Europe and northern Africa, typically on calcareous, well-drained soils at 300–1200 m altitude. It prefers full sun and dry periods, with a deep root system.

Pollination is primarily by native bees and small butterflies; seeds are dispersed over short distances by gravity and light winds. The species shows drought tolerance and seasonal flowering during dry months.

Essence oils from sage-dusteni have a sage-like aroma and have been studied for antimicrobial properties. While not widely cultivated, it is used as a garden ornamental and in experimental phytochemistry.
