Randonnée - Incontournable (Segment)
A forested ridge with the "Staatswald Hohnbachtal" borders on the Lontzenerbach and the Hohnbach, which is littered with wild daffodils in spring. The wild daffodil or yellow daffodil (Narcissus pseudonarcissus) is endangered in its stocks and strictly protected. According to its heyday, it is also called daffodil.
Also not to be overlooked are the many beautiful calamine violets in the Hohnbach valley!
The unique calamine flora is particularly evident in the months of May to August. Galmeiflora or calamine vegetation is the botanical name of two plant communities of metallophytes on soil containing heavy metals. The unique calamine flora is particularly evident in the months of May to August, when the calamine particles bloom in the calamine corridors.
Galmeiflora or calamine vegetation is the botanical name of two plant communities of metallophytes on soil containing heavy metals, their respective species and namesake in Latin (violetum) form the two endemic calamine violets. Specific occurrences are called calamine lawn or calamine meadow. The galmeiflora is one of the galmei plants and forms a pedobiome on a heavy metal lawn.
In the border triangle near Aachen, it owes its Latin name violetum calaminariae and its uniqueness to its type, the yellow calamine violet (Viola calaminaria), which is only widespread here. As the first botanist, she has Prof. Dr. Mathias Schwickerath (1892-1974) under the name "zinc plant society". In addition, the plant community, which forms the violet palm tree pansy with Haller's foam cress (Arabidopsis halleri) (Violetum guestphalicae), is regarded as a separate subform of the palm tree flora. However, the absence of the calamine cabbage and the presence of Haller's cress, which is missing in the border triangle of Aachen, moves her to another heavy metal corridor, the carnation corridor.

The yellow calamine violet (Viola calaminaria), yellow calamine pansy or short calamine violet is an extremely rare species from the genus of violets (viola) in the violet family (Violaceae), which can only be found on soils containing heavy metals in the area of Aachen occurs. In its scientific name, viola means "violet" and calaminaria "belonging to calamine". It is a close relative of the yellow pansy of the Vosges and the Sudetes pansy and part of an alpine ice age relic flora. However, it is not directly related to the violet calamine pansy (Viola guestphalica).
Because of its binding to soils containing heavy metals, the yellow calamine is endemic to the border triangle around Aachen, its distribution is restricted to this area.
Palm tree violets are protected. They may not be picked or dug up. Numerous alpine meadows in the Aachen area are nature reserves.
