The high cowslip ( Primula elatior ) is a species of plant that belongs to the genus of primroses ( Primula ). Another common name is forest cowslip (Switzerland). Its inflorescences appear as early as March as one of the first signs of spring on damp meadows, on the edge of the stream and in the alluvial forest .

description

The high cowslip is a perennial herbaceous plant that reaches heights of about 10 to 30 centimeters. The leaves, which are hairy on both sides, stand together in a basal rosette, reach a length of about 20 cm and gradually merge into the winged petiole, becoming ever narrower. The edge of the sheet shows an irregular and fine perforation.

The pale yellow flowers appear from March to May. The flowers are larger and lighter in color compared to the real cowslip ( Primula veris ). In contrast to the real cowslip, the throat of the cowslips is golden yellow and the calyx is close to the petals. In addition, the flowers are only slightly scented. However, it is primarily the different location requirements that contribute to the distinction between the two types; the real cowslip can only be found in dry meadows, bushes and light forests.

The cylindrically shaped capsule fruits of the high cowslip stand on stiff upright fruit stalks and are usually longer than the calyx.

The number of chromosomes is 2n = 22.

ecology

The cowslip nectar is located deep down in the flower tube. Therefore, only long-nosed species such as bumblebees and butterflies are considered pollinating insects . In bees , however, you can sometimes observe that they bite open the corolla tube from the outside in order to get the nectar in this way.

The cowslip is one of the so-called desiccation spreaders . The fruit capsules that contain the seeds roll back in dry weather, allowing the seeds to be scattered. In damp weather, the capsule teeth curve inward again and thus close the capsule.

The plant is used among other things, the caterpillars of the endangered butterfly species Perlbinde and Hamearis Lucina as a forage crop.

The high cowslip is attacked by the rust fungus Puccinia primulae .

Occurrence

The high cowslip is widespread in Europe and inhabits eastern Turkey , northern Iran and Armenia , Azerbaijan and Georgia in the Caucasus region and southern Siberia in the Russian Altai Republic .

The cowslip is often found in herbaceous oak and hornbeam forests , in floodplain and ravine forests and in mountain meadows. It prefers moist, nutrient-rich and base-rich, loose soil, even in shady locations. It indicates clay soil .

In the Allgäu Alps, the species in Bavaria on the Rauheck rises up to 2300 m above sea level.

After Ellenberg it is sub-oceanic spreading, a weak acid - weak base to pointer, lives on nitrogen-rich sites and is a Ordnungscharakterart of broadleaf - mixed forests and related companies (mesophytic, buchenwald like deciduous forests of Europe ( Fagetalia sylvaticae )).

Subspecies

One can distinguish the following subspecies:

  • Primula elatior (L.) L. subsp. elatior
  • Primula elatior subsp. amoena (M. Bieb.) Greuter & Burdet : It occurs in Turkey, Armenia and Georgia.
  • Primula elatior subsp. intricata (Gren. & Godr.) Widmer : It occurs in Central and Southern Europe.
  • Primula elatior subsp. leucophylla (Pax) WW Sm. & HR Fletcher : It occurs in Poland and Romania.
  • Primula elatior subsp. lofthousei (Hesl.-Harr. f.) WW Sm. & HR Fletcher : It occurs only in Spain.
  • Primula elatior subsp. pallasii (clay.) WW Sm. & Forrest : It occurs in the Middle East.
  • Primula elatior subsp. pseudoelatior (Kusn.) WW Sm. & Forrest : It occurs in Turkey.

use

Tea is made from the flowers and roots of the high and the real cowslip , which has an expectorant and expectorant effect.

High cowslip varieties are also used as ornamental plants. The so-called Elatior hybrids Primula × polyantha are, however, despite their name, do not descendants of the High cowslip, but come from the intersection Primula veris x vulgaris , the genuine and the stems lots cowslip (see below).
