Vegetative characteristics

The sage germander is a perennial herbaceous plant and reaches a height of 30 to 60 centimeters. It has subterranean runners . The stem is mostly branchy at the top and generally short-haired shaggy.

The opposite arranged leaves are divided into a petiole and a leaf blade. The petiole is 1 to 2 inches long. With a length of 3 to 7 centimeters and a width of 1.5 to 4.5 centimeters, the simple leaf blade is heart-egg-shaped to elongated with a heart-shaped or truncated spreading base and a densely serrated leaf margin. The leaf blade is very nervous and somewhat wrinkled.

Generative characteristics

The flowering period extends from July to September. The flowers sit singly or in pairs in the axils of very small bracts and stand together in a more or less one-sided, loose, long, cluster-like inflorescence .

The flowers are at a length of 9 to 12 mm zygomorph double perianth . The chalice is tubular-bell-shaped, bent down and shaped like a helmet with two lips. The crown is pale greenish yellow, the tube reddish in color.

The Klausenfrucht ( broken fruit ) breaks down into Klausen. The Klausen (partial fruits, nuts) are spherical and almost smooth with a diameter of 1 to 1.5 millimeters.

The number of chromosomes is 2n = 32 or 34.

ecology

The sage germander is an herbaceous chamaephyte in a mild climate and otherwise also a hemicryptophyte and stem plant. Vegetative reproduction occurs through underground runners .

The diaspores are the Klausen together with the durable cup. The cup takes on the function of a biological capsule. The Klausen spread as animal and wind spreaders as well as rainworms, in addition, a processing spread by birds . The fruit ripens between July and September. The fruits are winter dwellers. The long-lived seeds are light germs .

Occurrence

The sage germander occurs from Madeira via Tunisia and western Europe to southern Scandinavia , in western central Europe and in the western Mediterranean region to the southern Balkans . It is a sub-Atlantic floral element .

In Austria it is found scattered to very rarely, in Switzerland it is widespread.

The sage germander is mostly widespread in the western and southern parts of Germany, in the north it is scattered or rarely occurring. To the east it can be found scattered as far as Thuringia, Saxony and the Bavarian Forest; it is very rare in the German part of the Alps. In the Allgäu Alps in Bavaria, it rises on the Jochstraße between Hindelang and Oberjoch to an altitude of 1100 meters.

The sage germander grows in sparse deciduous and coniferous forests, woodlands and heaths. It thrives best on soil that is not too dry and is a little more common on a lime-poor substrate than on a lime-rich substrate. It often thrives on moderately dry to fresh, nutrient-poor and base-poor, acidic, musty-humic, mostly sandy-stony loamy soils in a mild, humid winter climate. In Central Europe it is a character species of the Quercion roboris association, but also occurs in the Pruno-Rubion fruticosi association. In the north and east of Central Europe it occurs in companies of the Trifolion medii association.

Habit as a cultivated plant

Use as a medicinal plant

In some areas, the sage germander is used, for example, as a wound remedy, similar to the sage species.

The sage germander is used as an “ active ingredient ” in homeopathic medicines. It is said to help in particular against tuberculosis , which has not been scientifically confirmed.
