ecology

Herbarium evidence of the stem leaves. Because of its endangerment and rarity, this species should never be collected!

The common cone is a hemicryptophyte .

There is no second flowering after mowing. The vegetative propagation takes place via runners or root shoots ( to be observed especially in autumn after mowing .)

Occurrence and endangerment

The common umbel occurs in Eastern Europe and Western Asia (Western Siberia). The western border runs on the east coast from southern Sweden into Germany and Austria. It is a continental floral element, that is, the core area of ​​distribution is continental Europe; she avoids the Atlantic climate. It is rare in Central Europe . It occurs in Europe in France, Germany, Denmark, Sweden, the Czech Republic, Austria, Hungary, Poland, Lithuania, Latvia, Estonia, Slovakia, Moldova, Russia, Belarus, Romania and the Ukraine.

In Germany, Selinum dubium is rarely found in north and north-east Germany, Thuringia, Saxony, Hesse, northern Bavaria and the middle or northern Upper Rhine Plain. It was classified in 1996 in Germany in category 2- = highly endangered.

Selinum dubium grows in moist to wet, sometimes flooded, lime-poor, acidic, but base-rich to (weakly) calcareous, basic areas. It prefers non-fertilized, nutrient-poor litter meadows on humus and silty soils. Selinum dubium is a characteristic of its own society (Cnidio-Violetum), which belongs to the association of the Cnidion, to the moor meadows.

Taxonomy and common names

Earlier the species as a different genus which was Cnidium ( Cnidium ) considered to belong. The scientific name is then Cnidium dubium (Schkuhr) Thell.
