The Plant Geography Section in Numbers

The concept of a garden arrangement after plant geographical principles goes back to Anton Kerner, botanist in Innsbruck, Tyrol (1831-1898). The plant geography section in our garden was developed in 1897-1904 by Adolf Engler (1844-1930). It comprises about 13 acres, on which ca. 6,400 plant species are cultivated.

In 12 rock beds plants are shown from:

  • Scandinavia
  • Iberian Peninsula
  • Central European hills
  • Alps
  • Carpathians
  • Balkan Peninsula
  • Middle East
  • Himalayas
  • Central Asiatic mountains
  • Japan
  • Atlantic North America
  • Pacific North America

Forest types are available from 8 different regions of the World:

  • Forests of Central Europe (7 types: Hornbeam forest, Beach forest, Oak forest, Mixed forest, Pine-Birch forest, Riparian forest, Mountain forest)
  • Pontian forest
  • Hyrcanian forest
  • Mountain forest of the Himalayas (West- and East-Himalayas)
  • Siberian forest
  • Japanese forest
  • Forests of Atlantic North America (deciduous forest)
  • Forests of Pacific North America (coniferous forest)

In addition poor and rich fen, heath, steppe, altogether 7 types:

  • Tomillares (grazed limestone heath of the Iberian peninsula)
  • Atlantic heath (grazed SW-European broom-heath)
  • NW German heath (Calluna- and Empetrum-heath)
  • SE-European steppe (Pannonicum)
  • Central Asiatic steppe (Turkestan)
  • Californian Artemisia-steppe
  • North American longgrass- and shortgrass-prairie

Particularly extensive are the

  • Meadows with about 405 plant species, of which 70 are on the German Red List;

The maintenance is in the hands of head-gardener M. Beyer and 14 gardeners.
It is organised in 3 departments:

  • PG-01, theme: lowland- and montane vegetation of Germany, Scandinavia, Iberian peninsula, Alps, Apennines, Carpathians: 30,220 square m, kept by 5 gardeners.
  • PG-02, theme: Balkan peninsula, Middle East, Central Asia till Siberia, Himalayas, China, Korea: 23,910 square m, kept by 6 gardeners.
  • PG-03, theme: NE-Asia, Japan, Pacific and Atlantic North America: 27,930 square m, kept by 3 gardeners.

Altogether about 4000 taxa are shown here.

In connection with this area, but not freely accessible, is a nursery of 2,450 square m, with 600 square m glasshouses and 360 square m cold frames. Here about 2,400 plant species are cultivated by 4 gardeners.
