A drought-tolerant aromatic subshrub that flowers long into late summer; honey bees visit it heavily, making it a valuable garden plant for the summer dearth.
A subshrub from the dry, stony and limy slopes of southern Europe, the Caucasus and Central Asia, grown in gardens and small fields. Eastern European and Russian beekeeping sources list it as a good honey plant; honey bees and wild bees visit its flowers from morning to evening. Its nectar is good and its pollen contribution moderate.
Its blue-purple, rarely pink or white flowers open from July to September. Its main advantages are its long flowering and the fact that it keeps secreting even in drought; it stays in flower even in dry, unirrigated gardens.
Plantings are small, so no monofloral honey is known; it gives mixed late-summer honeys a pleasant aroma.
It is very well suited to apiary surroundings, dry banks and borders; it grows easily from seed and stays productive for several years. A hard prune in spring keeps the plant dense. The pure essential oil distilled from the plant can be harmful to humans in high doses; there is no known problem with the honey.
